Absolutely love the colors, size and condition of this beauty!!!

@Woopaul5fantastic teeth!! beautiful examples across the board, thanks for posting!

Sometimes I acquire a specimen simply because it's pretty, regardless of how common the fossil might be. Also to continue the Moroccan homage, here is such an example:

 

Otodus obliquus

 

~3.01" - 7.65cm

I am sure that is true for the Niobrara as well. There have to be huge collections of this stuff floating around.

Here's a Cretoxyrhina mantelli tooth that's pretty ugly, but also pretty big ..

 

~2.285" - 5.80cm

 

Cretoxyrhina mantelli

Late Cretaceous

Niobrara Chalk

I added the photo on the right on page 26 to give a better sense of scale on this particular tooth.

All natural Otodus obliquus from Morocco, but featuring one cusplet and one shoulder

[isurus90064]

@Untitled .. very nice natural Otodus! especially how the shoulder is merged into the crown with the other side being a distinct cusp.

@Woopaul5 beautiful Cretox! Looks like a good 1.75" and if so, the anterior would have been very large.

Thank you!  I have an odd fascination with Moroccan teeth- lots of cool stuff to come out of there, but it requires a lot of searching to find them.  Here’s another all natural Otodus with a unique multi-colored enamel:

Cretoxyrhina mantelli from Mississippi 

[Untitled]

A 1 15/16” Otodus mugodzharicus from Aktulagay, Kazakhstan.  This one also has serrations on the very base of the crown, but doesn’t extend far enough to be considered an aksuaticus.

Very very nice Cretox from an less common location and a beautiful Otodus example from Kazakhstan!!

Aktulagay

Thank you!  You have an awesome, more advanced transitional in your post you linked as well.  I love the preservation of Aktulagay teeth.  I saw that your previous post mentions that Cretalamna has been found in Aktulagay before, have you happen to have seen any of those before?  

 

Here's a super interesting tooth from a different part of Kazakhstan- what I have labeled as an Otodus mugodzharicus, BUT from the locality in Tushbair that produces Bartonian aged teeth; much more recent than when mugodzharicus would have been around.  Any thoughts?

 

[isurus90064]

Assuming the label is correct and just looking at tooth characters, from an enameloid perspective, I don't really see an O. mugodzharicus, but more of an classical O obliquus (except for the sigmoidial distal edge). The root seems much more recent though. Can't really see how compressed the tooth is. Sometimes these contradictions in individual teeth can be confusing. Having said that I would not solely use the presence or lack of serrations as a cross-referencing factor of age of the originating formation. or if it even is in the ball park.

 

Also, the tooth seems small, so aside from variability, ontogeny could be getting in the way here too. If the tooth comes from Tushbair and if the formation is the Shorym, it is odd that there is not the slightest hint of serrations.

Thank you for the in-depth response!  This tooth came from the Middle Eocene locality where the Otodus lineage would be well-serrated by this point, which is why the collector I acquired it from thought it was a parotodus.  He is highly respected in the community so I don’t doubt that it did come from this locality, though I don’t believe it is a Parotodus.

Is there a hint of a nutrient groove present? If so, I would guess this is Tethylamna.

NICE!! pretty much a locked out location now.

I don’t think it it a Techylamna- it is much more robust and has a much more substantial dental band than any techylamnas I’d encountered.
