Ray Versus Shark Vertebrae - How to discern?

[JamieLynn]

Howdy! How do you tell a Shark Vertebra from a Ray Vertebra? I can't seem to find much info online about Ray Verts. I came across (and vaguely remembered reading on a post) that ray vertebrae are more rectangular....is that true?  Here are a few vertebrae that I think might be ray and if I could get a positive yay or nay on that.....I'd be very grateful! 

 

These are from Post Oak Creek in Texas - Cretaceous Era

Size 4mm

Size 3 mm

OH dear...so that just made me way more confused. Ah well....so ray verts are essentially the same as shark verts and good luck figuring out which is which. hahahhaha
