Latest trip

Last time I was there last Sunday. There are teeth that I found. Also rays!



Now invertebrataphylism!

Today my Dad was in our main scientific library (ЦНБ) and found there some books about microfossils and mollusks. I began studiyng my mollusk collection, and found many interesting specimens.

Gastropods; Quaternary, Eocene, Cretaceous
 There are other Paleozoic invertebrates.


Sharkophylism

I wasn't blogging for at least 2 months! But now everything will change...

I had now collected more shark teeth, and therefore more complete ones.

The Best and The Most Complete Teeth
Lamniform teeth are the most common teeth in this location. Odontaspidids win in numbers, while Otoduses in size. On the first photo, the top tooth is perhaps from Otodus mugozdarhicus. My first thought was Otodus aksuaticus (for photos of their well-serrated teeth look here), but then I realized that my tooth was only partially serrated, so I now think that it is or Jackelotodus or Otodus.


Mostly unidentified teeth; central - Otodus
