deebler Posted December 4, 2018 Share Posted December 4, 2018 My son and I found two fossils. We don't have a clue what they are. Can anyone help us? Link to comment Share on other sites More sharing options...
FossilsAnonymous Posted December 4, 2018 Share Posted December 4, 2018 No expert on these things for sure but from similar posts pic#1 some sort of ammonite/gonatite fragment (ribbing) and number 2 could possibly be some sort of clam. This is pure guesswork however, take what I say with a grain of salt. It is very helpful for us to get the best ID if you tell us exactly where you found it On The Hunt For The Trophy Otodus!

deebler Posted December 4, 2018 Author Share Posted December 4, 2018 Thank you for the fast reply. We found them in Southern California about two miles from the Pacific ocean on a hill. Link to comment Share on other sites More sharing options...
Bronzviking Posted December 4, 2018 Share Posted December 4, 2018 The second one looks like a Brachiopod. Link to comment Share on other sites More sharing options...
Barby Posted December 5, 2018 Share Posted December 5, 2018 They are fossilized bivalves-- clam-like. They look similar to a common shell which is frequently found on beaches here in Florida. The live ones have varied "stripes" of tan, cream, and brown. They are commonly found in the fossil shell pits here, also.If these are what you've found, they are:FAMILY:CARDIIAE GENUS:Dinocardium SPECIES:robustum Link to comment Share on other sites More sharing options...

The shell posted here is from the Pacific Ocean Coast, Southern California. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 5, 2018 Share Posted December 5, 2018 The first one is part of the outer whorl of an ammonite with some ribbing. The second is an equally nicely ribbed bivalve. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

That covers a lot of ground. Can You be a little more specific? Most of the coastal exposures along the California shore are much to recent for ammonites. I think the first is a snail.

Barby Posted December 5, 2018 Share Posted December 5, 2018 I don't think the top one is ribbing on an ammonite-- it looks like the end of one of the bivalves in the other pictures. It appears to have the same size and structure of the others... Link to comment Share on other sites More sharing options...

If You could better expose it - that may help get an ID. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

abyssunder Posted December 5, 2018 Share Posted December 5, 2018 I think the first one is a weathered internal mold of a bivalve with some shell remnants embedded in the matrix. 2 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Barby Posted December 5, 2018 Share Posted December 5, 2018 I agree with Abyssunder ---this one does look like an internal mold-- the shell has eroded away, but the sediment, or matrix which subsequently filled the space which once housed the animal--took on the shape of the interior. Is that another mold of a univalve in one of your other pics?Looks like a snail, but is really the shape of the inside? Link to comment Share on other sites More sharing options...
