archimedes

For the February field trip, six stalwart fossil hunters ignored the gloomy forecast and journeyed through a storm front to a lovely Franklin County lake site.  As it turned out, the weather was perfectly suited to fossil hunting with partly sunny skies, comfortable temperatures and a fresh breeze - no rain the entire day!  Accompanied by the sound of waves lapping the shoreline, the amiable group had no trouble finding many different Mississippian fossils:  Crinoid stems and several whole crinoids with calyx and arms, bryzoans (Archimedes), blastoids, horn corals, bivalves, unresistable (sizable!) hash slabs and even coral heads at a second site.  For a day with a marginal forecast, a good time was had by all.   

Okay, how many of you let a 90% chance of rain stop you from coming on the field trip?Six of us showed up to hunt fossils in spite of the predictions of 90% rain over the entire south.  The weather report was correct this time!  It didn't rain on the way there, lulling us into believing it would hold off most of the day.  With such a small group we decided to go to a location where we have not been in several years.  This location has a very poor road with large potholes, not much room to park, and a short hike to get to the lake. On the way to the first site, we got quite a scare.  The sky lit up like a fireball, and there was an extremely loud explosion, like dynamite.  Later as we headed to another site, we saw a huge oak tree that must have been 3-4 ft in diameter, literally blown to pieces, and they had recently removed the large limbs from the road.  It looked like someone had blown it up.  It was about a mile from where we had heard the explosion.After minor sprinkles and even periods of no rain at all, the minute we got to site one, the rain started.  We tried to wait it out to no avail.  The rain was as determined as we were.  However, everyone was in a good mood and ready to collect fossils, so we donned our rain suits, ponchos, and rubber boots, grabbed our umbrellas, and walked down to the lake in the rain. This location has a lot more mud than what we are accustomed to.  The intent was to avoid one of the more muddy roadside cuts, but we managed to get just as muddy here as we would have at the other location.  We found a number of rocks with weathered out fossils showing extremely clear detail, and the first rock Ann picked up contained a trilobite.

At site two we found numerous horned corals, the bryozoan Archimedes and its filter feeding structures (fenestrae), crinoid stems, a trilobite, blastoids, and tiny shells, and of course the ever present rocks covered with fossils. After that we decided to proceed to another site along the lake where large corals have been found in the past. We also found a complete crinoid head and legs, which was the find of the day. Around five o'clock as the rain had still not let up and a chill wind started blowing, we decided it was time to head home. Most of us decided to stop at a local steak house for dinner where we dried out, warmed up, and filled our bellies.

A large crew of BPS members and guests headed to northwest Alabama this month, in hopes of finding crinoid heads and trilobites. Well, we found both! We left Birmingham expecting a high of 50, however, that must have been in the wee hours of the morning, as the temperature hovered in the mid-30's all day. Brrr!! But that didn't keep the fossils inside, nor did it deter detemined fossil seekers.

Our first stop was a roadcut where numerous specimens of coral were found, many too large to carry home.

The second stop was another roadcut, where numerous pieces of archimedes were found, a few horned corals, and even a whole crinoid head!

At stop #3, our primarly collecting location, a lake in NW Alabama, fossils were litterally laying all over the ground. Almost every rock was covered with weathered out fossils which stood in nice relief, and many had weathered out totally, so that individual specimens could be found by carefully examining the ground. At this site, numerous blastoids were found, archimedes, two types of coral, crinoid stems, trilobite parts, and Jan N. found a tiny, complete, rolled up trilobite! On a side note - the trip photographer had a difficult time organizing a group picture, and did not manage this feat until stop #3
- imagine trying to control a herd of cats who see FOOD, and you have a good idea! But it was finally managed with only 2-3 missing (already in action, hunting those fossils!).

Our last stop of the day was a different location on the lake, where similar items were found as at stop #3, and also some larger corals and crinoid "legs".

As it got colder and colder, people were calling for warmth and food, so we made our way to an out-of-the way steak house where we continued to talk about fossils and visit until our bellies were full, and finally after a wonderful day spent with like-minded friends, we left for home.
