A Mammal vertebra? and 2 unknowns from the Miocene

Recommended Posts

Ludwigia

I visited my favorite shark tooth site in the Miocene Burdigalian again today and along with the usual teeth I dug out the following objects. The first is obviously a vertebra, and I don't think it's fishy, but rather mammalish in my humble opinion. But I'm not at all sure about that. I've found teeth from Cervidae here before, so I'm thinking that maybe that's the case with the vertebra? Measurements: Ø13-15mm x15mm. long.

I haven't got a clue on the next 2 items. The first is 10x4mm. and the second 15x5mm.

Any suggestions would be appreciated.

I thought that somewhat resemble a ray tooth. :headscratch:

i do think the second is part of a ray dermal plate.  The vertebrae with its essential hollowness  from both sides looks like shark vertebrae to me.  the third I have no idea.  Hopefully someone else will recognize it.

A not-mammal vertebra.  The second object is more likely to be a fragment of a ray tooth plate than of a dermal denticle.  Third item remains a mystery.

The first specimen is a fish vertebra.  You can tell that by the vertebra being concave on both ends and by the notochord hole in the vertebra center.  The second specimen is a partial tooth from a ray dental plate.  No suggestions for the third specimen.

Thank you one and all for your expertise. I figured that last one would be a toughie.

Could #3 be some sort of solitary coral, just weathered oddly?

Interesting thought, but there are no corallites or other distinguishing features in view.

I think it is a steinkern of a solitary coral. Maybe photos of both ends would confirm it.

I was hoping to see a clear radial pattern. I don’t really see it but I still think it could be a solitary coral.
