I give talks to school children about the fossils of the
Ordovician here in Wisconsin and encourage them to bring
fossils for identification.  One brought a stumper a few
weeks ago.

A curator at the Milwaukee Public Museum sent a photo
of a similar specimen they'd identified as Gonioceras kayi.
Another cephalopod expert suggested it was a flat section
through the shell.  I'm not convinced yet...

Pictures of both fossils can be found at this page:

Any assistance or pointing in the right direction will
be gratefully accepted!
