stakks Posted April 22, 2012 Share Posted April 22, 2012 Anybody no any place I can look for help with id of this fish I found in rock Link to comment Share on other sites More sharing options...
BobWill Posted April 22, 2012 Share Posted April 22, 2012 (edited) Hard to tell but it looks more like a weathered ammonite. What looks like fins at the bottom may be ornamentation called ribs. The spiral in the center could be the outline of the umbilicus and the curved lines on the right look like septal walls. If it came from Texoma it is Cretaceous which makes it from 120million to 65 million years old. See if you can remove some of the matrix from the center. If I'm right you'll see more ribs spaced closer together. Edited April 22, 2012 by BobWill Link to comment Share on other sites More sharing options...
Bill Posted April 22, 2012 Share Posted April 22, 2012 Already been id'd on the ID board as a Productid brachiopod in cross section. KOF, Bill. Welcome to the forum, all new members www.ukfossils check it out. Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 22, 2012 Share Posted April 22, 2012 (edited) It's not a fish. I think the OP said it was found at Lake Texoma, so I don't know if there were productid brachiopods around in the Cretaceous. I would go with badly weathered ammonite. or cross section of inoceramid clam as suggested in another of the posts. It's not a fish, though.

stakks Posted April 22, 2012 Author Share Posted April 22, 2012 Sorry to keep asking but the more at it it has gills and a fin Link to comment Share on other sites More sharing options...
Auspex Posted April 22, 2012 Share Posted April 22, 2012 It has shapes which resemble gills and a fin. When interpreting marks in stone, it is tempting to draw conclusions based on first impressions, but further critical analysis is often called for.

BobWill Posted April 22, 2012 Share Posted April 22, 2012 (edited) You may be right with fish, they have been found at Lake Texoma, but consider the possibility of a much more common fossil from there. Notice the wavy lines at the top of your 2nd picture and compare them to the broken piece of ammonite above this ammonite. These are the septa or chamber walls inside an ammonite. Maybe that part of your fossil is worn away revealing the septa inside. Also the ribs on my ammonite are similar to ribs on a related species with ornamentation that look more like the "fins" on your fossil. Also notice the wavy spiral in the middle. If you chip away some matrix inside of that you may see the smaller closer together ribs from the inner whorls if it is an ammonite.
