Four Triassic teeth

Recommended Posts

FF7_Yuffie

Found these four, if someone can take a look. All from Bull Canyob.

 

1 - A preondactylus tooth. 5mm. Now, I know this is from Italy, so I'm guessing name is wrong. But is it pterosaur?

 

2 - Fabrosaurus. 3mm

 

3 - Prosauropod. 4mm

 

4 - Eudiomorphodon - 2mm. Another species I thought was from Italy.

 

 

Many thanks

Thanks very much. I'll look more into the pterosaur and eudiomorphodon teeth.

 

I see other places selling pterosaur teeth from Bull Canyon as Peteinosaurus, which I also thought came from Italy. But could tooth number 1 be a peteinosaur?

 

I'll get more info on both.

None of the Italian Peteinosaur had skulls so a tooth ID might prove difficult but those sellers might enlightening you with a source.

@Troodon

 

I did some further digging in the Eudimorphodon tooth.

 

Got in touch with a paleontology institute and their pterosaur expert who had done some work with Italian pterosaurs took a look. Figured you might be interested to see his opinion on the tooth.

 

"The tooth in the picture is different from the teeth of Eudimorphodon and other taxa with prevalent tri- to quinticuspid dentition (Carniadactylus, Seazzadactylus, Austriadraco etc.). It is more similar to some teeth of Austriadactylus, but it could belong to any archosauriform,in my opinion. Teeth morphology is convergent in many groups of Triassic reptiles, thus they are scarcely useful for a reliable taxomomical identification"

Hi Troodon,

 

A few years ago, a friend gave me a sandwich bag with some Bull Canyon matrix.  I found some tiny conical teeth, a few teeth like that "fabrosaur" which were called Revueltosaurus (now considered a pseudosuchian as you noted), a couple of serrated teeth that look more like a dinosaur (but maybe some other archosaur), and a few Reticulodus teeth, including one nice one.  You just don't get good jaw sections and bones in that.  You get lots of bits.

Gosh you just triggered a memory of a batch of Bull Canyon matrix I sorted ages and ages ago.  Need to go find out what I did with the finds.  But its pretty rich.  The problem we have identification of these teeth is that indeed everything is isolated no jaws with teeth to be able to describe.

1) could be a range of things. I wonder if it might be fish, actually, or an amphibian like Koskinonodon.

 

2) could be Revueltosaurus or might be a silesaurid such as Kwanasaurus. Unlikely to be an ornithischian; there are no confirmable ornithischian fossils in the Triassic of North America.

 

3) this could be from a range of archosaurs. 

 

4) I have the gut feeling this is also silesaurid.
