Patellilabia sp.

Osagean Series
Fern Glen Formation

Patellilabia sp. Patellilabia sp.

This specimen was originally incorrectly identified
as a Platyceras. Thanks to Dr. Anderson, we now
have the correct identification.

Viewer Comments:

Patellilabia have a flared aperture where Platyceras have elongated
apertures. The specimen you have figured is really nice.
