I hate to burst anyone's bubble, but in cleaning skates and rays to eat, all the verts I have ever seen have been round. I wonder if those fossil oval verts might belong to squatina type sharks? Just a loose, ungrounded thought. Does anyone have an extant (dead) Squatina to compare?
Now I'm curious to know what some of my own small (<1") "oval" shaped verts are from because I always thought they were squatina as well. If anyone has images of what they think are ray and squatina verts it would be nice to see. Either way though, I've never seen a vert over 2" in diamter belong to anything other than a large species of shark or fish. Maybe the clue is in the septa?

Pat,
That the oval verts in question would be Squatina verts makes a whole lot of sense: they do resemble the Squatina vert pictured in LCIII, and I've always wondered why they're nearly all the same size! Thank you. Ok, then I guess the question stays: how can one tell if something is a ray vert?

It shows an example of what the author believes is a Squatina vertebra (fossil) and tooth.
