MSirmon Posted May 17, 2019 Share Posted May 17, 2019 I found this in Benbrook Tx which is a Cretaceous area. Is this Mortoniceras sp.? im going to attempt to clean between the ribs but am tempted to try and keep some of the matrix attached where the embedded bivalves are. I think they tell a great story.

-AnThOnY- Posted May 17, 2019 Share Posted May 17, 2019 I would generally say yes, but something about the ribs looks like its trying to be an Oxytropidoceras 1 Link to comment Share on other sites More sharing options...

Let me undress it and see what the ribs tell us 1 Link to comment Share on other sites More sharing options...
ClearLake Posted May 26, 2019 Share Posted May 26, 2019 The ribs look too narrow and widely spaced for any of the species of Mortoniceras I see in my book. There is Oxytroidoceras texanum found in the Goodland Formation (which is around Benbrook) which looks similar to what I can see of your specimen. The adult rubbing on this species is fairly widely spaced, high, rounded and club shaped on the margin which I think I see in your pictures. Do you have a picture looking at the edge so we can see the profile and what the keel looks like? 1 Link to comment Share on other sites More sharing options...

ClearLake Posted May 26, 2019 Share Posted May 26, 2019 Yep, makes me more confident of O. texanum or something very similar. No grooves on either side of the keel rule out Mortoniceras from my understanding. Link to comment Share on other sites More sharing options...
