Texas Ammonite Fossil

Here are pictures of two Texas ammonite fossils. This fossil is from the Cretaceous Period that was found in Tarrant County, Texas.

Thanks to Herb for the fossil.

The pearly one looks like a "Metoicoceras" ammonite prolly out of Eagle Ford formation. The flat ribbed limestone one is prolly an "Oxytropidoceras" ammonite (internal cast) out of the Goodland formation.

Thank you for the identifications. I will pass them along to the person who gave me those fossils.

You have a nicely done website (

Good luck with your future fossil hunting!
