Greetings fellow fossil enthusiasts!
I don't know what this thing is. I've shown it to several other fossil guys in Houston and they don't know what it is either. I think it's from a fish of some sort, other than that I have no idea. I found it in Hogtown Creek in Gainesville so it's probably Late Miocene-Pliocene. Scale bar is in Millimeters. Any help is greatly appreciated.
