Brachiopods found that day included the very fragile inarticulate brachiopod,
Pseudolingula. There are 4 specimens on the rock shown below.
This site is in the Arnheim formation. And so it's the lowest formation in the
Cincinnatian series where the Brachiopod Leptaena is found (below).
Here's a nice cluster of the tiny Brachiopod, Zygospira. This rock
is made entirely of this brachiopod!
Among the clams found included this beautifully preserved Caritodens!
Another type of fossils found were annelid worm tubes called Cornulites.
The specimens below are much larger than usual. Nice!
There were many straight shelled Nautiloid Cephalopods found. The one below was found by new member Richard Adams. It was recovered, from the slab it was
found, in both by Richard, a Student of Indiana University East and current member Peggy Branstrator, Lecturer of Biology at Indiana University East as
The Cephalopod below was encrusted by something, but it's all calcite
And finally, quite a few gastropods of the genera Cyclonema
That's all! Our next field trip is June 11. Hope to see you there!
