Cephalopod??

[Texas21]

Looking for a little help identifying these. I believe they are from Northeast Texas. Acquired these when my dad past away. Sorry I don’t have more info to share.

You will get better replys if you posted this request in the "Fossil ID" topic. This is for non fossil rocks and minerals.

They are ammonites, but as to what genus/species I can’t say. 

 

If you think they were from Texas, maybe some of our Texas members might know.

I see no one has responded with an ID.  I think the reason why is that the photos don't really reveal some of the needed detail to make a confident identification.  For example, it's hard to see what type of keel (outer edge) the specimens have.  This is a key detail for ID.  Also, no suture pattern is displayed, which is also a key feature in ID.

 

Having said all of that, from the ribbing and general shape, they both look to me like Mortoniceras sp. ammonites, which are common ammonites found in the Duck Creek Fm. in N. Tx.  That's about the best I can do from the details seen in the photos above.
