Fossils Found That Day, Part I
Lots of trilobites were found that Saturday. But the best
find, perhaps, was this beautiful specimen of the crinoid Plicodendocrinus
casei. Note the anal sac at the top of the calyx. It's broken, but helps
identify this specimen easily. It also looks very much like the specimen Jack
Kallmeyer showed us in his slide show, the night before the field trip, of
fossils we might find.
If that crinoid wasn't the best find, perhaps this coveted Conularia
specimen was! It was a real eye-popper.
Another great find was this excellent coiled nautiloid
cephalopod. A member traced along the layer suspected to have these large,
unusual cephalopod and was persistent enough to find a nice one! Note the
Calcite crystals in the second photo.
Other fossils found include the Brachiopod Glyptorthis
There are layers on this site that are almost entirely
brachipods. The rock shown below is a good example of shingled Rafinesquina.
Lots and lots of the Horn Coral known as Grewingkia were
