Staurikosaurus tooth from New Mexico???

[Compy]

Dear experts,

 

this is my second aquisition:

According to the seller it is a "Staurikosaurus" from the Bull Canyon Fm. in New Mexico (no information on the county provided).

The length is 1 cm and the width is about 3 mm.

I tried to count the denticles but unfortunately my camera is not made for close-ups. The count might be around 7-8 per mm.

 

In contrast to my last post where there was a wrong formation provided by the seller I was able to verify, that the Bull Canyon Fm. does in fact exist in New Mexico.

But that's almost it. According to wikipedia Staurikosaurus is only known from Brazil which makes it unlikely for the tooth to be a Staurikosaurus pricei. On the other hand there is a website on triassic vertebrates of New Mexico which also lists Staurikosaurus pricei in this formation...

 

Here are the compressed pictures of my tooth:

You are correct that species is only known from Brazil.  I doubt that tooth is dinosaurian but very little is published on teeth.  Only one dinosaur is described from the Bull Canyon Fm Gojirasaurus quayi.  See attached post to provide some info on triassic dinos from New Mexico.

Thank you very much!

So I think it is the best to label it "unidentified tooth" until we have mor knowledge on this formation, isn't it?

"Indeterminate Tooth" is best
