August 25, 2007 - Pennsylvanian Fossils, Tuscaloosa Co, AL
A trip to a non-working mine site to explore spoil piles for invertebrate fossils was on the menu for BPS's August field trip. The mining company, headquartered in Tuscaloosa county generously offered us the opportunity to explore at this site. A long, hot day on a moonscape was nevertheless a great trip, yielding some beautiful specimens.
We met with the mining engineer who gave us a quick overview of the mining operations, then let us go onto the piles to do our hunting. We hunted until the heat got to us and it was time to seek air-conditioning.
After cooling off at a Mexican restaurant, we ended the day at the Museum of Natural History at Tuscaloosa with a visit to their superb collections.

February 17, 2007 - Mississippian Fossils, Franklin Co, AL
Once again, the word, "intrepid" comes to mind when BPS makes a midwinter trip! With the temps in the upper 30's and low 40's and 15-20 mph winds, it was a toss up as to which trip to this site was the coldest! In spite of the weather, around 23 fossil seekers came for the fun. Our first stop was under sunny skys and slight winds which brought the temperature up to a bearable level. This is a great site, featuring a prehistoric coral reef that always has excellent specimens washed out during the previous year. It's always a temptation go after the big boulders, but they're much larger than they look (like iceburgs) so we can only stand and drool and capture them on camera. At the first stop on the lake numerous specimens of blastoids, archimedes, and crinoid stems were found, and a very nice piece of petrified/ permineralized wood. Next we went to the other side of the lake where it was downright windy and bitter cold. More crinoid stems, straight cephalapods, and some unknown specimens were collected as well as great slabs of fossil hash. These make great teaching tools as well as attractive showpieces. We were also treated to the sight of Bill "walking on water!" Next we stopped at a roadcut which yielded a few more nice specimens, and a lot more icy wind. After one last site check, hunger was the issue, so most of the group organized to follow Greg, who always seems to know the best places to chow down, to a long enjoyable evening meal at a "secret" local steak house, After a great time of good food, rehashing the day and catching up, tired BPS members headed home.

On to the next stop, where we were given an overview of the collecting area.
Shoreline of the lake, water is way down in winter.
Horned coral.
A sponge?
Horned coral.
Nice brachiopod.
Most rocks in the area consist of numerous small fragments of fossils. Most visible on this specimen are crinoid stems and bryozoan (or the netting material from archimedes.)
Parts of very large, but broken, blastiods.
Tiny gastropod.
Unknown round fossil.
Another unknown fossil.
Very nice specimen of petrified/permineralized wood.
How'd he do that?? Bill has found several nice specimens. Click, then click again for larger image.
Nice cephalopod.
Brachiopods.
After the lake, we collected at a nearby roadcut.
Numerous specimens of burrow casts were found, and also a few straight cephalopod's (in middle).
At the last stop of the day, geologic layering is very prominent.
Tall people have a distinct advantage!
