Dry Dredgers Field Trip
April 28, 2007
Middletown, Ohio
Second Site
We moved on to a second site, which was a road cut just a mile or so away.
This was a great site for viewing the Arnheim Formation. We found some nice
things there, too.
Fossils Found on Site 2
The second site exposed a layer of the Arnheim that has a fairly rare
brachiopod. But it's abundant in this thin layer. The name is Retrosirostra
carleyi. It looks somewhat like a Hebertella, but the
triangular pedicle opening stretches along the pedicle valve. Here are 4 photos
of ones found that day. Note in the first picture, the pedicle opening is
visible, but, unfortunately, is covered up with debris. A modesty shield! :-)
There were lots of Rafinesquina too.
