How old are these fossils?

[FossilGuy24]

I found these in Medina County Texas on a hilltop.  What is the age of these fossils and any other information that can be provided would be greatly appreciated.  Thank you.

They are from the Glen Rose Formation (106-115 million years old) which is Cretaceous in age.

 

I don't have any identification on the clam, but the first item is likely a type of Gyrodes gastropod.

Looks like Glen Rose preservation to me too.  Best confirmation would be to compare exact location to a geo map.  If the site is sensitive to interlopers, you can do this yourself or with someone experienced via PM.  If it is secure private property, you can ask for help openly here.

Something for scale would be helpful. Your last one may be brachiopod rhynchonella.

Sorry @Innocentx.  Here you go...

Nice finds. I was out that way last weekend scouting for new locations, but was more in the Marble Falls & Canyon Lake area. Will have to head a little further west to your neck of the woods next time!

I think your gastropod might be close to Lunatia.

The snail may be a bit small for Lunatia, although would be a good possibility. Just that there are many many types of gastropods in the Glen Rose. The clam appears to be of the genus Arctica, but not sure about species. The other two fossils appear to be the pecten-like bivalve Neithea.

I'm really glad you said correctly Arctica, not Artica like others. Neithea might be good for the bivalves.
