Some older fossils

Recommended Posts

Shellseeker

I was out hunting today, and found some unusual stuff for me. Example of a known is this Galeocerdo contortus . I do not find them with this level of preserved serrations. To me this means a likely Miocene location.

So three (3) requested IDs

 

First:

Second: In a different location a week ago, I found the one on the left.  Maybe concretion,  with strange circular "pore"... but then the one on the right today.  So this is something, possibly fossil or what?

Last, A Ray mouthplate: Worn , very thin,  Can someone id the specific ray?

Thanks for all comments and replies.  A VERY interesting day with many unique and unknown (to me) fossils.

Hi @Shellseeker well, I know that your second image is probably a rostral from a sawtooth fish.  Here is an example of one from the Belgrade.  As Gesh stated the round ones are Tilly bones. I just picked up four of them on the Savannah River this weekend.   Overgrowth of bone on a fish vert.

These are:

I think the concretion-like things are tilly bones. See here.

Almost painful to look at aren't they ?

I agree....

 

The first it's a rostral tooth for a Sawfish and the second one tilly bones.

I’m kinda confused how you came to the conclusion the serrations meant Miocene? Contortus is usually Miocene, and serrations are a matter of preservation...

Yes, I can see the confusion... You are correct, quality of preservation has little to do with age of the location or the era in which a specific fossil existed.  I was pleased that I was finding G. Aduncus & G. Contortus in such high quality that I wanted to make a point that it is VERY rare for me to find either with this detail on serrations.

 

My hunting grounds are a mixture of miocene, pliocene and pleistocene. Based on experience and results, pleistocene fossils dominate. My chances of finding Nannippus are 1 in a thousand compared to Equus chances. So when I use the term, likely miocene location, I am actually saying that I am far more likely to find miocene species, than is normal for me.

Generally, in my Tiger Shark finds, Curvier dominates with Contortus playing the role of Nannippus. Yesterday I found 8 Contortus, 5 Aduncus, 1 Curvier in a mix of hundreds of small shark teeth.

We found 10 Anoxypristis teeth, which is also very unusual...plus a number of other unusual finds for me.

I am not sure this is  a miocene location, have to go back and see the results over many trips.

Definitely - always makes me think of the elephant man.

Hey hi Jack,

Physogaleus contortus (GIBBES, 1849) extinct Tiger-like shark  is common in the STH fauna.

There is very little wear on STH shark teeth. Of the ones I have found maybe 20 % are serrated and the rest are not.

PS Nice finds!
