whowat13 Posted May 28, 2015 Share Posted May 28, 2015 I got this from a friend of mine this past weekend... Other than the fact that it is a vertebra, and that it looks reptilian to me... I know absolutely nothing about it. I hope someone can help ID it for me, but I am not holding my breath... -Bill Link to comment Share on other sites More sharing options...
Troodon Posted May 28, 2015 Share Posted May 28, 2015 I would lean toward a garfish vertebra Link to comment Share on other sites More sharing options...

Diceros Posted May 28, 2015 Share Posted May 28, 2015 Either the longnose gar Lepisosteus, or the more derived alligator gar Atractosteus. Actually, gar vertebrae are sort-of the opposite of reptile vertebrae - they're opisthocoelous (the concave side of the centrum is posterior), unlike the typical procoelous (the concave side of the centrum is anterior) reptile vertebrae (most lizards, snakes, crocs; but not dinosaurs). In your first photo (the dorsal view), anterior is toward the top. Opisthocoelous vertebrae are unusual, even for fish. 4 Link to comment Share on other sites More sharing options...
