danco Posted January 9, 2013 Share Posted January 9, 2013 (edited) Here are some ray fossils (Dasyatis? Pliocene/Miocene) from Hoevenen (Antwerp) Belgium, millimeter thin. Some say they are dermal scutes, other that they are layers of vertebrae (epiphysis?). Thanks for helping me to ID them.

jpc Posted January 9, 2013 Share Posted January 9, 2013 could this be a limpet? Link to comment Share on other sites More sharing options...
Plax Posted January 9, 2013 Share Posted January 9, 2013 really does look like a limpet! I'd go with the ends of bony fish verts? Just guessing of course.... Link to comment Share on other sites More sharing options...
Auspex Posted January 9, 2013 Share Posted January 9, 2013 They somewhat resemble the denticles from a Bramble Shark, with the 'thorn' broken off.

Al Dente Posted January 9, 2013 Share Posted January 9, 2013 I've seen Cretaceous dermal denticles that resemble these but they never have a hole in them. I would guess they are broken vertebrae. Link to comment Share on other sites More sharing options...
PRK Posted January 9, 2013 Share Posted January 9, 2013 (edited) Im not sure what they are but It looks like the large piece on the left fits right into the large piece on the right! they are mirror images, positive, negative.

danco Posted January 9, 2013 Author Share Posted January 9, 2013 (edited) I forgot to mention that the image pictured the same 3 items seen from the top (at the left) and from the bottom (at the right). They are bowl-shaped, 1-2 mm thin of the wall. Edited January 10, 2013 by danco Link to comment Share on other sites More sharing options...
cowsharks Posted January 10, 2013 Share Posted January 10, 2013 I'm fairly certain these are broken ends off vertebra - but the ones I've seen in person were from shark verts and much larger. Link to comment Share on other sites More sharing options...
danco Posted January 28, 2013 Author Share Posted January 28, 2013 What about the bump in the center? Limpets do not have such a thing. Link to comment Share on other sites More sharing options...
Coco Posted January 28, 2013 Share Posted January 28, 2013 It exists several species of limpets, some have a hole in the summit, the other not. And those who haven't hole can have one when they died and used by sea currents. http://www.google.fr...4Q9QEwBQ&dur=62 Coco ---------------------- OUTIL POUR MESURER VOS FOSSILES : ici Ma bibliothèque PDF 1 (Poissons et sélaciens récents & fossiles) : ici Ma bibliothèque PDF 2 (Animaux vivants - sans poissons ni sélaciens) : ici Mâchoires sélaciennes récentes : ici Hétérodontiques et sélaciens : ici Oeufs sélaciens récents : ici Otolithes de poissons récents ! ici Un Greg...

Carl Posted January 28, 2013 Share Posted January 28, 2013 I'm with Al Dente and Cowsharks. I've seen many vertebra preserved like this from the Late Cretaceous of NJ. When one articular surface of a shark vert breaks off and gets weathered you see the radial pattern of struts from the interior. Plus they look phosphatic rather than calcitic.

evannorton Posted January 28, 2013 Share Posted January 28, 2013 Here are pictures of some limpets I found while on vacation in Mexico for reference. Sorry for the poor image quality. Link to comment Share on other sites More sharing options...
PaleoRon Posted January 29, 2013 Share Posted January 29, 2013 Fragmentary vertebra, probably fish. Link to comment Share on other sites More sharing options...
