Nice STH megs @Woopaul5!!

[isurus90064]

With regards to the Aetomylaeus sp. examples I posted earlier, here's a great reference:

 

"The Neogene fossil record of Aetomylaeus (Elasmobranchii, Myliobatidae) from the south- eastern Pacific" - Jaime A. Villafaña, Giuseppe Marramà, Sebastian Hernandez, Jorge D. Carrillo-Briceño, Dirk Hovestadt, Rene Kindlimann & Jürgen Kriwet, 2019.

Not the longest planus I've seen from STH, but it feels a lot bigger than any of the other 2"+ planus I have from STH.

Hi isurus90064, (though I have heard that is not your real name)

 

I didn't know about that article.  This one looks interesting too:

Thanks Jess for posting that link, had not seen that yet.

 

I've always thought isurus90064 really rolls of the tongue nicely.

I have the first issue of Palaeontos, a great reference for Oligocene teeth.  In fact it was a gift from Rene, one of the authors of that Aetomylaeus article.

I remember when all that stuff was coming out of Chile.  I didn't see many ray plates and I don't think I saw one with as many teeth as that one.  Nice!

[isurus90064]

Considering there is only one very large ray known from these deposits, it seems likely that this very large ray barb is from the same species.

 

I've seen a few ray plates come from here but never the barb. The discoloration is just color, the actual damage speaks for itself.

 

So, going out on a limb here :-):
