Acheroraptor from Hell Creek Fm., Montana

Recommended Posts

Hello dear all,

 

after a long and stressful time I finally was able to acquire some new teeth and to try to figure out (to my best ;-)) what they are or might be…

After reading these really helpful guides on the Hell Creek teeth I tend to label this tooth as Acheroraptor temertyorum 

The serration count is between 17 and 21 (actually i counted 17, 19 and 21, depending on the location +-1 inaccuracy)on a length of 5mm

The length (CBL) is approx. 1.1 cm

According to the seller it is from the Hell Creek Fm, Montana. 

 

Would you agree on Acheroraptor?

Serration density count is done at the midline of both carina so that value should be consistent.   You really need to compare both carinae to determine if its possibly a Dromaeosaurid.   Do you have a locality where this was found?

I’ve asked the seller and according to him it’s Garfield County.

Unfortunately the tooth has only serrations on the distal side, the mesial side is either too worn or doesn’t show serrations, I cannot really say. Was it that what you meant when saying to compare both carinae?

 

I’ve attached some better pics from the seller for I don’t have the proper equipment with lighting e.g. for good macro shots…

It's Acheroraptor

When purchasing teeth make sure you obtain a complete provenance because that's key in identification.   You should try to avoid teeth that do not have both carinae dentulated because often its necessary to understand the difference in identification

Thank you very much for your help. With a limited budget (and import taxes and all that stuff) it is pretty hard for me in general to get material other than that from Morocco and when so to get an at least acceptable quality… :-(

But I definitely see reason for getting well preserved teeth when wanting to identify them as best as possible.
