Very nice, congrats! 

[Tidgy's Dad]

Very interesting to see specimens from more unusual locations. 

Thanks for showing us.

Will be posting more Kazakhstan teeth from other locations (in Kazakhstan) soon.

Gorgeous teeth. If these are in your collection, could you tell us more about how you obtained them? Personally collected? Trade or purchase?

I had a friend who was going to the Tuscon show, years ago, and gave him an amount of money to buy some very nice Kazakhstan teeth.  He did very well.  I have bought some more Kazakhstan teeth recently from a seller on the internet and will soon be buying more species that I don't have in my collection.  Am I allowed to say who it is without violating any Fossil Forum rules? I am rather new on TFF.

Nice teeth. Isn’t Isurolamna inflata a sand tiger (?) that is thought to have evolved into Cretalamna?

Naming sellers in the open forum is not allowed.

You can send a sellers name in a PM.

I don't know, sorry.  Maybe someone else can answer.

Isurolamna inflata is younger than Cretolamna.

Here are three more teeth from Kazakhstan.

 

1. Archeolamia koepingensis

2. Meristodon nugaitensis

3. Paratodus mangyshlakensis

Nice teeth! What part of Kazakhstan are the two Cretaceous teeth (1 and 2) from?

[ThePhysicist]

Is Isurolamna inflata described from Mangyshlak, or is it only I. bajarunasi? If both are present, how are they distinguished? Or are they synonymous?

the one from the bartonian sediments is bajuranasi,

Sorry, I should have listed that information.

 

Meristodon is from Nugaity and is Cretaceous

Archeolamna is from Tykbutak and is Cretaceous

Paratodtus is from Tushbar, Mangyshlak and is from the Middle Eocene.

Hi Don,

 

I think it was in the mid-90's that teeth from Kazakhstan and eastern Europe started appearing at shows like Tucson and Munich.  Hardly anything had come out before.  Teeth were very common at some sites but they were hit hard and you started seeing less of it by the late 90's.  These days, you see some recirculation of specimens from that time as collectors sell/trade some of their extras.  It's possible hunters have been checking on some of those sites too.

 

Most of the teeth I've seen are Eocene - some early Eocene but mostly Middle Eocene (Bartonian) and some late Eocene (Priabonian) - but also Cretaceous, Paleocene, and Oligocene.  I tried to get a sample of everything possible and found a couple of taxa I missed years later (like Squalus from the late Cretaceous of Tyk Butak, Kazakhstan).
