July 21, 2007 - Cretaceous Fossils, Greene Co, AL
A very large group of 31 people showed up for the July BPS trip to Greene county. Thanks to James Lamb, our trip leader this time, we visited some Cretaceous sites that we have not visited for at least 10 years, so we were all pretty excited. The first site was a chalk gully which has produced nice mosasaur bones in years past. James Lamb gave a short training session on how to collect in chalk gullies, how to walk around in them (slowly and gently), how to collect (when you find something, look up-hill to see if there are more), and other collecting tips. There are numerous pieces of what looks like rubble scattered throughout a gully - each piece of "rubble" is actually part of a fossil, though most of them are unrecognizable without close examination, sometimes under a microscope. James Lamb checked some areas where fossils had been found in the past, and discovered another bone, which was flagged so that it could be retrieved on the way out. Bob found a bone which turned out to be part of a turtle. Also, we found a wide variety of other fossils, including another mosasaur vertebra, a couple of mosasaur teeth, Tylosaurus flipper bone, several shark teeth, including a large one found by Sylvie. Ammonite pieces, worm tubes, burrows, a tiny fish tooth, a fish vertebra, and oyster shells were also found. One member asked James to go check some bones she had flagged; he discovered they were bones of a recent rabbit, and as he was approaching her to return the flag, he asked "Are you keeping that mosasaur vertebra there by your foot?" Well . . . She would've had she seen it first! Many fossils are light colored and blend in well with the environment. It takes time to adjust ones eyes to be able to spot them. We also discovered some fresher fish bones, leading to the conclusion that the birds who regularly raid the catfish farms have been using the gulley as their dining hall. Though we were hot and dripping wet, we were willing to stay longer, wondering what was in the next gully, and the next, and . . .
After rounding up the gang (which is a minor miracle in itself!), we hiked back to our vehicles for lunches, then headed for the creek. Finally, time to get wet and cool off! Out with the sieves, from collander baskets to "real" geology sorters, to home made wood-sided screens. At least a dozen ptychodus teeth turned up - Claire may be the "winner" on these, she had found 6 at last count. Every screen we searched had several shark teeth, and other fossils were also found, including a large fish vertebra, gastropod steinkerns (internal molds), worm tubes, and one very nice arrowhead. We left relatively early (hey, some of us would have stayed til dark if we could have!), and many of us stopped by a famous BBQ joint to continue the fun and fossil discussion.

Wesley found a very nice point.
Headed home after a wonderfully pleasant day of collecting!
May 19, 2007 - Cretaceous Fossils, Montgomery Co, AL
Another hot day found the troops begging for a "water field trip" so we could cool off. We had mixed feelings about what we saw when we got there and found that drought conditions had virtually dried up the creek-bed. On the other hand, a good deal more fossils were exposed. This is our favorite spot for collecting echinoids and viewing too-fragile-to-collect ammonites. A few ammonites were retrieved, echinoids, cretaceous wood, worm tubes and a few shark teeth and numerous shells were found, and Becky found a turtle bone. With the exposure of the creek-bed, we could see near-perfect circular holes in the rock where the last bits of the ammonite fossils had washed away over time. In spite of the heat, we all found some nice fossils (or drooled over other people's fossils!), and had a chance to get a good look at the underlying rock formations. Our finds made all participants feel the day was truly worth it, including the largest shark tooth that this group has seen at this site, two very large shark vertebra, an unusual looking pycnodont fish tooth, and what might be a plesiosaur bone. Then off for some dinner at a wonderful BBQ restaurant where all expressed delight with the trip and made our plans for future visits.

April 21, 2007 - Cretaceous and Tertiary Fossils, Butler Co, AL
The April field trip took us to Butler County where a creek has cut through early Tertiary and late Cretaceous sediments. Once again as with last months field trip to Green County we had some of the best spring weather Alabama can offer, with the temperature reaching a pleasant 76 degrees.
Everyone met at a central location, and a brief introduction to the geology of the area was given before driving about 12 more miles to the entrance to the site. While past trips to this location have found the entrance roads to be very slick from rain, this years access was dry and easy. The entire caravan was able to drive to the limestone hilltop parking area.
The fossil hunting started the moment you exited your car with small gastropods and segments of large ammonites being found on the cleared hill top. The trail down to the creek provided more ammonites.
The creek was beautiful with white quartz sand beaches at many of the bends. Shark teeth, ray teeth, fossil bone, ammonite pieces and nautiloids were found in the gravel bars, along with numerous non-fossilized bones and teeth from various mammals. Some of the more interesting finds were various human artifacts rather than fossils. Indian potshards, some with incised decorations, a couple of projectile points and an Indian pipe, probably of European origin, were found.
The end of the day found the diehard fossil hunters resting at the beach where the trail intersected the creek. The Novaks organized a fire on the beach to roast small sausages, while others brought snacks to contribute, and the Stewarts returned to the parking area to set up camp for the night and fix their dinner.
By dark, everyone headed home, leaving Pam and Bob to enjoy a pleasant night at the site with owls hooting and Whip-poor-wills calling. At daybreak turkeys could be heard at the tree line adjacent to the camp area. After a couple of hours of walking the creek on Sunday morning the Stewarts packed up and reluctantly left the site, letting it return to nature.

Vice President Greg gives an overview of the geology of the site and collecting rules.
A lot of excited people showed up for the field trip - fossils can even be found on the limestone earth in the foreground.
If you look carefully, you can spot tiny round gastropods, each approximately 3/8 inch across.
Hiking down to the creek from the parking area (and of course, looking for fossils along the way!)
The creek was higher this year than normal, but there were still numerous gravel bars.
A recent storm had washed up a huge pile of brush and trees, and left behind rocky rubble and mud rather than the white sand we normally find.
Nice nautiloid found by David.
Ray tooth and shark tooth.
Unknown item, can anyone identify? Looks kind of like a tooth. . . .but . . . .
Nice turritella in coquina.
Lea's mom was visiting from the Czech Republic, and decided to join us for the fun!
Shells in matrix.
Probably a pottery handle.
Worm tracks in the sand. Fossil worm tracks much like these are found in shale in north Alabama.
Numerous clayballs were found in the creek. This one shows bits and pieces of plant debris. The finder did not examine it closely to determine whether these were fossil leaves or recent, however, based on the geology of the area, they could easily be cretaceous fossil remains.
While Bob & Pam set their tent up . . .
The others built a fire and enjoyed the evening.
The campfire has about died out as some of the diehard fossil hounds hang out wringing that last little bit of enjoyment from the day!
August 19-20, 2006 - Cretaceous Fossils, Lowndes Co, AL
Once again BPS was out in the boonies with the ATV’s! Greg even brought his own ride this trip. Go, Greg! Gorgeous weather, good turn-out. Sandy Ebersole, a new BPS member from the Geological Survey of Alabama, was interested in examining the formation to determine if it is part of the same Ripley Formation she is studying at Coon Creek in Tennessee. Sandy and Jun Ebersole both gave us a short overview of the formations and geology of the area before we started collecting, which left us with an excellent perspective on where we were going.
We explored several small creeks in the area for the first time, where we found a number of crabs and other items, including clams, in nodules. Sandy found an outcrop in the first creek where she gathered numerous samples for her research.
The main creek yielded great samples for all: more crabs and clams, and unknown items in concretions. Sandy located another interesting outcropping and took more samples of microfossils. Michelle found some nice ammonite pieces, including one piece showing beautiful suture marks.
Since the Ebersole's needed to leave that night, our hosts set up an impromptu trip to a gully for the evening. Sandy and Jun wanted to see if this was part of the Ripley Formation (current thought is - probably not). Jun got a quick lesson on ATV driving and we hit the gully where we found teeth and bits of shells.
The next morning before the mist had burned off, we went to a different gully that had not been explored for several years, but did not yield many finds. After returning to camp, and meeting new arrivals, two groups were formed. One group went back to the creek where the crabs had been found, and another group consisting of Vicki, Michelle and Becky took off on a scouting adventure to explore yet another “new” creek. This turned out to be a great spot with some decent finds of brachiopods, clams, gastropods, exogyra, shark vertebrae, and possible pieces of bone.
Later in the day, diehards Becky and Vicki explored the main creek again, using a different access point and went a little ways up the stream until the creek got too difficult to navigate.
After two days of excellent collecting, all went their way home and look forward to the next field trip.

On the way again! Riding to the site is almost as much fun as the collecting itself!
Sandy and Jun provide handouts and short lectures on the geology of the area.

Taking a rest after a long, hot day on the creek.
Jun and Sandy probably had more fun than the rest of us getting to the next collecting location - this was Jun's first opportunity to drive an ATV!
After a bit of a rest, we decided to explore a gully late in the afternoon.
This is how the gully looks when you get closer to the ground - a lot of shell bits and pieces. Can you find the shark tooth in this picture? It takes a while to get one's eye attuned to the coloring and patterns.
Early Sunday morning, we headed to a gully that had not been surveyed in several years. No items of interest were found here, mostly bits of shells and broken nodules, and a lot of caliche.
Closer view of the ground and a nodule.
After the gully trip, one group headed back to the main creek for crabs, and the Three Musketeers, Becky, Vicki, and Michelle, headed off for an adventure to find and scout a new creek.

Finally, we made it to the creek, which was littered with shells, primarily exogyra.
Exogyra.
More exogyra pieces. The slightly circular pieces with the dimple in the middle are the other half of the exogyra, though we did not find any articulated specimens.
Exogyra and a couple of gastropods found by Vicki.
Nice bivalve found by Becky.

Small vertebra found by Vicki.
Bone, but unfortunately, it appears to be recent.
Last creek to be explored.
This rock filled with shells was found at this creek, but not much else, so all headed home.
June 24, 2006 - Cretaceous Fossils, Montgomery and Elmore Co, AL
A relatively small group of BPS members went to a creek in Montgomery County for today's trip - could it be some people were scared off by the thoughts of 95 degree weather in the sweltering sun? To get an idea of our weather, go to your bathroom, turn the shower on the hottest it will go, close the door so steam can build up, turn off the A/C, then take your laptop in there and view our trip photos - you will have a good idea of our day! Leisa brought her canoe, and she and Claire floated/pushed/dragged it upstream and then back down. This late Cretaceous site once again yielded numerous echinoids and ammonites, though most of the ammonites could only be "collected" via photos, due to their fragile composition. We also found huge quantities of shells, a few shark teeth, a couple of mosasaur vertebra, two large vertebra, possibly shark, and pyritized coprolites.
Several people decided to call it a day after getting too hot for comfort. After a refreshing afternoon lunch in an air conditioned restaurant, the die-hards brains began coming up with another potential collecting site in Elmore county. Since we have a canoe, lets go look for petrified wood. Now understand, we had one canoe, one paddle, 3 life jackets and 4 people to go on this escapade. After a quick stop at the local discount store for an additional paddle and PDF, we scouted access points. The put-in we decided on was steep. Really steep. Really really steep. But we finally got it down the several hundred feet to the water, only to find a boat wasn't necessary, the water was low, the shore was easily walkable, and petrified wood was everywhere. So we collected it (ask Jan how much his pack weighed!), took some pictures of a tree that was about 4 feet in diameter, and noticed it was getting darker. And windy. And there was thunder. And lightning. And lots of cold rain (boy, did it feel good!) And we had the canoe at the bottom of a huge hill. But Leisa, resourceful as ever, had a plan; just hook the boat to her van, and pull it out.

May 6-7, 2006 - Cretaceous Fossils, Lowndes Co, AL
This May found the troops encamped in Lowndes County for a whole weekend of fossils and good company. Tents, camping vans, pop-up trailers all turned out for the great weekend of food, hunting and sleeping out thanks to the generosity of the hunting camp. Our hosts supplied rides out to gullies and a creek on their property via ATV’s and trailers. Even Sylvie made the bumpy ride out to the creek, although some of us did do a quick, quiet poll as to who knew how to deliver a baby or how long it would take to make it to the nearest medical facility, JUST IN CASE she hit one bump too many! We had a great crowd, and some excellent specimens of fossil crabs, shells, ammonites and various teeth were found. After a long day of collecting, we gathered around a roaring fire for a low country shrimp boil and good conversation. Everyone seemed to be demonstrating that everything does taste better outside! Michael and Sylvie had left early, Sylvie declaring that she was now ready to go home and have a baby!
Even the rainstorm that burst on us Sunday morning didn’t dampen spirits. Sleeping with the rain pounding down while you are warm, dry and cozy is one of life’s lovelier experiences! The early risers gathered under one of the many “porch” shelters in the camp and revved up the little propane stoves to make breakfasts of pancakes, cereal, coffee, tea...all the comforts of home, but more fun. Finally, all but the most dedicated decided to call it a day and head home. Nancy left a few of her belongings behind, so Vicki and Martha decided to return them via Selma, wait out the storm and do a little more looking around before heading back.
It was great to see so many of us, old and new members AND guests, turning out for all or most of the weekend. THANK you to our hosts for making us feel so welcome and providing all the facilities. Also thanks to our hosts, and to Shannon and Jim for providing vehicles and trailers, and to Vicki and everybody who helped organize the weekend and the shrimp boil!
This month we were collecting in the Ripley Formation, Cretaceous Period, Maastrichtian Age. According to information published by George Martin, Soil Data Quality Specialist with the USDA, most (if not all) of the crabs found on the trip are Avitelmessus grapsoideus Rathbun, or “Muffin Crabs.” These crabs have been documented from the Ripley Formation in Alabama, Mississippi, and Tennessee. Along with crabs, members also found numerous teeth, including mosasaur, sawfish, swordfish, and various types of shark teeth. Also found were numerous shells and pieces of ammonite.

A long drive by ATV, then a short hike to the gully.
The gully where we began the day.
Greg has just given instructions on "how to collect in a gully", so everyone is being very cautious and searching carefully.
This is a rather small gully, with very little chance of getting lost here. Gullies in the Ripley are very unusual.
Sometimes it was easier and more productive to just sit in one spot and let one's eyes get accustomed to the patterns.
The gully is littered with numerous pieces of broken shell, nodules and sometimes fish and shark teeth.
Loni's grand-daughter has found a sawfish tooth.
Lea has found the bottom part of a bivalve, possibly exogyra.
Shannon has found a new use for our logo patch - his son John's backpack.
Melanie has found . . . something . . . .
Tooth from a late Cretaceous swordfish, probably Protosphyraena.
Sylvie has found part of a crab leg.
Small fragment of ammonite showing the tell-tale intricately patterned suture marks, which distinguish it from a nautiloid.
Mosasaur tooth.
A variety of shark teeth, and the long upper left one is a swordfish tooth.
After a really hot morning, we returned to camp for lunch and a group picture. Uhh.... where's Claire, did we leave her??
Members spread out to search the creek bottom and banks. Some go upstream, some go downstream.
Nice crab. Note the dark gray clay. It is quite slippery in the creek and along the shore.
Some nice crabs.
An odd round item found by Vicki.
A closer look at the "round thing".
Rychard has found a nice deer skull, recent, not a fossil.
Back in camp, the food fun starts! Members and guests enjoyed a fine low country shrimp boil, with head chef Greg Mestler. Numerous members contributed to its preparation and its disappearing act!
THIS JUST IN ! ! SYLVIE AND MICHAL ARE THE PROUD PARENTS OF ELI MRUG ! Born May 23, 2006.
August 20, 2005 - Eocene Fossils, Covington and Cretaceous Fossils, Montgomery Co, AL
What a hot, humid day this was! According to weather reports, the temperature hit 97 where we were collecting, and there was virtually no shade. The first site we visited in Covington county was a real dud, for multiple reasons. We knew there would be a "constant steady discharge" due to some future plans at the dam. However, we didn't anticipate this discharge would raise the water level 3-4 feet above normal! This meant our normal collecting areas were underwater, way underwater, and we weren't prepared to scuba dive. We spent a short period of time collecting the few shells, teeth, and horned coral found in the banks, and getting hot and sweaty, then left early for our second site in Montgomery county. Much better collecting at this site! Members found a good number of shark teeth, ptychoda teeth, ammonites, and two unique finds, part of a turtle, and another item that we haven't seen from this site before, which is still being identified. According to Vice President Greg Mestler, in the late 1980's on another BPS field trip to this site, he found mosasaur skull bones in the same area where we found the turtle. Hmmmm.......
Once again, the group ended the day with a fine opportunity to hang out together at The Swamp, a kinda - sorta local eatery (only 20 minutes away, huh, Greg?) where we stayed way too long, but enjoyed the time spent with fellow fossil hounds.

Searching for shells, teeth and horned coral in the clay banks. Note how high the water is behind us.
The water was very high, severely impacting our collecting. Sylvie is walking in a spot that is normally dry. Even the island is flooded.
In spite of the high water, some nice shark and ray teeth were found.
Shells in matrix. They are very fragile and crumble easily, so are difficult to collect whole.
Ok, this isn't very productive, on to the next site!
At our second site, the water was high so a safety rope was necessary.
The site is cretaceous. Each layer has a unique set of fossils.
Searching for echinoids and shark teeth.
Greg explaining proper excavation techniques.
Ron found an unusual heart-shaped item which turned out to be a disk from a dear vertebra. It is very light-weight and recent, not a fossil.
Fragments found here are still being identified. Look just above the yellow handle to see the first "rocks", then straight to the left. There are some more fragments in the upper right quadrant. Some are probably turtle.
Closer view.
Greg has exposed more fragments, probably turtle.
James had an opportunity to practice making a protective plaster jacket.
Nice ammonite found by James.
Rychard carefully excavates an ammonite.
A close-up view of a ammonite found by Rychard.
Tracks of a recent visitor, a large alligator . . .
Paige, get out of the water, you look just like gator bait!
Ron's other interest is gold panning, and he gave some of us a demo, using gold bearing material he found in Georgia.
Greg, turn around! They told me to quit taking pictures of people's rear ends!
What a group of tired, sweaty people. So where do we go to cool off and relax a while?
The Swamp, of course! Our favorite restaurant on the Alabama River.
May 21, 2005 - Cretaceous Fossils, Montgomery Co, AL
This month, BPS members headed to Montgomery county to collect in the late Cretaceous. Another beautiful day for being in the woods, and playing in a creek. This year, the creek was down, way down, so moving from shore to shore was much easier than our last trip. A number of nice echinoids and ammonites were found, a variety of shells including gastropods, and a few shark teeth. Most of the ammonites at this site are not collectible due to their fragile nature. Later in the day, members headed south to another creek for more collecting.
A few of the diehards ended up at "The Swamp", a really cool "hamburger joint" on the Alabama river in Selma. The owner is an engineer and designed the building to "float" when the river rises. Normal water level is about 80 feet, and in their 1st year of business it rose to about 120 feet - the restaurant floated!
