Kendall County, Blanco River bottom ID Fossils

Recommended Posts

Syrian

I joined the forum to get some help on IDing the fossils...

They were found in the Blanco River area of eastern Kendall County, Texas.  We find plenty of bi-valves and gastropods on a regular basis.

Most everything we find is from the cretaceous period and makes sense given our ranch location.

I've looked around for several months on the web trying to find something close to these below and can't seem to find anything.

The graph paper is .5 CM squares so most of these are just over an inch long.

I will let the experts give their opinions.

Thanks for your interest!

They look like steinkerns (internal molds) of a highly curved clam (unknown). The marks on the inside of the curve look like impressions of a hinge area. Local experts should be able to give a more specific ID. @Uncle Siphuncle @erose @JohnJ

 

To help us: any idea of what formation they are from?

They look like rudist steinkerns.  Search TFF and you will find very similar examples.

I can't answer your ID  question, but I know an auction site that you can pass them off as dinosaur claws on. :hearty-laugh:

I’d start with rudist steinkern as well.

Internal casts of Rudists?  :unsure:

Look like steinkerns of some type to Me.

Sorry no jokes on this one (from Me at least).

I think this is a duplicate thread because I just answered the same question/pictures on a different one.

Since I have little experience with rudists (or curved clams or claws or skulls:) my 1st thought would be very worn whorl sections of ammonites but they would have to be fairly evolute and from the body chamber unless they were some of the rare phragmocone pieces without septa or suture showing. Is that too vague? lol

My first thought was also rudist steinkerns, but what puzzles me is, that all have nearly the same curvature. No, wrong, not all have the same curvature...

Btw, the small squares are 1 mm large? Then most specimens are a little bit over 1 cm lage, about 1/2 inch.

You do not close your thread. It remains open unless an administrator or moderator finds a problem and: hides it; locks it to further replies; or deletes the whole thing.

Leaving it open allows future people to learn from the thread, in this way the forum becomes a sort of open encyclopedia that stores information for those in the future, while continuously creating new content.
