2020 Field Trip Reports

November 27, 2020 - Pennsylvanian - Jefferson County, Alabama

On Friday, November 27, 2020, seven BPS members and guests went to a working strip mine in Jefferson County to collect fossils from the Pottsville formation of the Pennsylvanian period.  The fossils collected today originated in a warm, steamy, oxygen-rich environment and grew to towering heights.  Some of the fossils found are pith casts, formed when sediments filled the hollow center of a stem and later hardened/mineralized into rock.  Other fossils are imprints and show beautiful details of fern-like foliage.
 
Some of the identified fossils found today include calamites, Lepidodendron, Stigmaria, Neuropteris, seed and cone fossils, brachiopods, gastropods and other inorganic remains (rain drops, fossilized waves and ripples). In one area, several cordaites with characteristic, strap-like leaves were spotted and photographed.  Several huge stumps were identified but were either too high in the debris wall or way too heavy to get into a car today.
 
The weather was ideal for quarry collecting today.  Early sun knocked the chill out of the air but clouds soon thickened which kept the temperature very pleasant.  Participants observed social distancing but still managed to keep up with the fossils that were being found.  All things considered, it seemed a very successful day.

March 21, 2020 - Pennsylvanian - Jefferson County, AL

On Saturday, March 21, 2020, a baker’s dozen members and guests of BPS went to a site that we’d never visited.  A tip from a member’s neighbor and a scouting outing was awarded by permission to collect in a strip mine in Jefferson County.  The spoil piles that held fossils were from the Pennsylvanian period – Coal Age fossils that were formed as warm moist coastal swamps gave way to periodic flooding and sedimentation during continental drift changes.  Interestingly, similarities between Pennsylvanian coal deposits in the Black Warrior Basin and those in South America indicate that they were once the same seam.  
 
During this time, as changes occurred, fossils of both plants and animals were very well preserved.  In the overburden piles where we collected, the majority of the fossils were lycopods, Calamites components, Cordaites impressions and fern-like plants.  Many lovely lycopod leaf scar pieces were found, along with Calamites pith casts.  There were numerous, large stigmaria casts, some with roots (hope some photos will demonstrate) and lots of lovely, very detailed fern leaf sections – most too fragile to collect except by photo.  In addition, a few bivalve and limpet fossils were found – some collected and some photographed.
  
The day was overcast and chilly and the recent rain covered all the cars with sticky grey mud but the group was too busy collecting to worry about minor complaints.  The area that was collected was huge – probably many more fossils to find there AND there’s a whole different area to explore.  Sounds like another field trip!

February 1, 2020 - Mississippian, Franklin County, Alabama

Trip number 2, for the win! On Saturday, February 1, 2020, eight BPS members and guests met in a parking lot in Russellville to gather permits, supplies and biscuits before returning to the lake where we had collected just a short time ago. The weather was nearly a repeat with gloomy skies and chilly temps and winds but no one was thwarted in the least. We intended to have a leisurely look along the shore that was so forthcoming last time but had a lucky change of direction instead. A long-time friend/member of BPS happened to spot, collecting on the shore, a local fellow he knew who HAD A BOAT and offered to ferry us across the lake to spots that are not as heavily collected. Yes, PLEASE!!! Several whole crinoids, a couple of trilobite pygidium, a possible large trilobite (on its side) and some nice hash slabs were claimed. When our boat captain had to go, he ferried us to the spot we had originally wanted to visit. We found a few blastoids, horn and other coral pieces, Archimedes, brachiopods, a badly broken shark tooth in matrix, and other fun bits of Mississippian fossil treasure. As the day extended and the wind continued, it was decided to make way back to the cars. At one point, it seemed like maybe more collecting would happen but the appeal of warmth and food overcame the need to collect more. That nice Mexican restaurant in Cullman was beckoning – food and conversation were enjoyed by those who stopped. Even though it was the second trip in short succession, it was a very good day!

January 25, 2020 - Mississippian, Franklin County, Alabama

On Saturday, January 25, 2020, several BPS members and guests decided, despite the dismal forecast, to travel to a lake in Franklin county to collect fossils.  The selected field trip site is a favorite and did not fail to please.  Despite the raw and biting winds and persistent clouds, our group visited 3 sites throughout the day.  Though two of the sites were less than forthcoming with fossil finds, one site was a treasure trove of Mississippian fossils.  There were lots of crinoid stems, many blastoids (one HUGE one), nice corals (also a HUGE horn coral), a couple of trilobites, some hash plates that were not to be left behind, a stunning arm of a feathered star crinoid and many other nice collectibles.  No one really wanted to leave the site but there was one more that we all wanted to visit so that’s what we did – staying until the daylight was all but gone.  It was probably the cold and the wind but we all decided to head home instead of having the usual Mexican dinner.  Even without the dinner and discussion, it was a good field trip.
