Fossil From Texas?

I found this fossil in my dad's rock collection. He could not remember where he got it from, but he thinks he got it from his dad, who lived in Texas.

It is sitting on a 3"x5" index card

Could you post some other views of the other side?

Looks like ammonite or ammonoid to me.

Hope the Texas crew weigh in.

Welcome!

It looks like a Jurassic Ammo to me, but im not 100% on that. Like Tim stated, hopefully some locals can help.

This is a good example on how the degree of weathering could confuse possible identification. The simple nature of the suture pattern made me think of a Paleozoic ammonoid until I saw the mention of it being heavily weathered.

Context is critical.

Welcome to the forum. Yes ,once you get wear past the suture it just shows the septal wall which becomes less intricately folded as you near the center. this makes identification difficult. Now you just have the characters like whorl profile,umbilicus size, over-all size and location to go by for a good guess. Not knowing the last makes it almost impossible, but a picture of the end might tell us something about the first two.

Thanks for all the good information all. I did not even think about the fact that it could wear through the suture pattern. I will post the end of it when I get a chance, but I don't have it with me right now.

Thanks again.

Looks like an old ammonite to me too. I found that attached one in a river bed north of Brooks Alberta.
