I love fossil hunting and found this fossil on my parent’s ranch 7 miles south of Hondo, (Medina County) Texas. The fossil is approximately 1 1/2” long and 3/4” wide. I need help identifying it and the approximate age of it.  Thank you and Happy New Year

Petrified animal Burrow?

Without info on the geology of the area, it’s  impossible to know an approximation of the age of the fossil in question.

Looks like a piece of a rudist, to me.

Calcite nodule for me.

If I've never seen one, and it's from Texas, it's a rudist. 

Seriously though, this texture concentric to the curved and tapered cylinder does it.

My first thought was rudist for the specimen in question, now I see that others have the same idea. It reminds me of caprinid rudists.

Yes, rudist for me also, caprinid or a part of ichtyosarcolites.
