Trace Fossils Found
The trace fossils in the next two photos we call "dumb bells" for
their shape, but they are actually Diplocraterian. They are
worm burrows, where the worm comes up to the surface of the ocean floor in two
places, making a pair of holes.
Another interesting trace fossil we found is this one, below, where the holes
are in a row as if the worm hopped from hole to hole!
Thanks to Jack
Kallmeyer for identifying this one. It's Rhabdoglyphus sp..
I have no idea what animal made the trace fossil below. But it is
interesting.
Brachiopods Found
Several examples of tight clusters of the tiny Brachiopod, Zygospira,
were found. The one below is amazing, but fairly common.
More often, the Zygospira were found in smaller quantities. The
ones below were exceptionally large in size, though.
Annelid Worm Tubes
Also found was an exceptionally large cluster of annelid worm tubes. called Cornulitids
(Cornulites and similar genera). It's a really nice specimen!
(next two pictures, before cleaning) It's pictured here upside-down.
Snails Found
Of course, there was a wide variety of abundant gastropods found. The ones beow are Cyclonema and Paupospira.
Spiders Found
And our field trip chairperson would not let us go without spying the living arthropods. This one appears to be a variety of Argiope. We were all amazed at the size of this species, which we found in great numbers on this site. Don't be afraid of them! Happy Halloween!
That's all folks!
Check out our next field trip to the PCS Mine, in North Carolina!
