Fossils Found That Day
Without a doubt, the best find of the day was this pyritized Edrioasteriod,
shown in the next two pictures. This was a variety of Cystaster.
It's interesting that this Edrio was found so low in the strata. It probably
came from the basal Fairview. The specimen was not well preserved, however. Some
mineralization (pyrite) has damaged the specimen. But I think removing some of
the shale will still reveal an impressive specimen.
The Pyrite which damaged the above specimen was everywhere on
this site. It shined brightly in the sunlight that day. Here's one nice patch of
Pyrite, found by a member that day.
Other nice find that day was this example of an interesting
"tar spot" remains of an animal that until recently was thought to
belong to Sphenothallus. I'm not sure if it has a name yet. But it
is one of the things we were hoping to find.
Crinoids
I saw only one crinoid calyx, found by a member. I think it was a Cincinnaticrinus varibrachialus. I wish I had washed it before taking this picture, so I would know.
Crinoid stems were everywhere. Greg Courney took a box of the
stem material home to clean and assembler them.
After cleaning them, Greg found a bunch of calyxes of the
crinoid
Cincinnaticrinus varibrachialus! Nice going Greg! Here are
some of them (next 5 pics).
Loose pieces of shale revealed the impressions of Crinoid
stems, as the picture below shows.
Another interesting variety of crinoid found, were
numerous examples of
Anamolocrinus incurvus
performing the "Crinoids Revenge" by encrusting Bryozoans
with their holdfasts.
See Cindy Striley's Site for more pictures of Anomalocrinus holdfasts she found
that day.
