The Jersey Devil Posted October 24, 2017 Share Posted October 24, 2017 They are both batoid (ray) vertebrae. 1 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

Al Dente Posted October 24, 2017 Share Posted October 24, 2017 Could be from a ray but Squatina also have very similar centra. 1 Link to comment Share on other sites More sharing options...

Carl Posted October 25, 2017 Share Posted October 25, 2017 The only safe thing to say is that that are chondrichthyan vertebrae because they are so heavily weathered. 3 Link to comment Share on other sites More sharing options...

The Jersey Devil Posted October 26, 2017 Share Posted October 26, 2017 You can definitely narrow them down to ray verts, they are not worn enough so as to be unidentifiable. The side structure that is exposed due to weathering (the bands visible on the side of the left vertebra in the second picture) is unique to ray verts; shark vertebrae will not have those bands when worn. Angel shark verts usually have cartilage attached, but even if the cartilage is missing, an Angel shark vert wouldn't have the little dimples present on the faces of these verts. 2 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

Here are some modern Raja centra showing this. These are from a clearnose skate I caught in NC. 10 hours ago, josephstrizhak said: but even if the cartilage is missing, an Angel shark vert wouldn't have the little dimples present on the faces of these verts I think the pits are a preservational thing. I've never seen modern batoid centra with these pits. 1 Link to comment Share on other sites More sharing options...

Interesting info. But do you know if there's a way to differentiate between ray and angel shark vertebra? There's still probably a better chance of these being ray verts since they are much more common in the area. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
