A selection of Hell Creek teeth

[FF7_Yuffie]

Hello, now, apologies for the photos. They're the best the seller can get, I'm afraid. But hopefully they are ok to get some sort of ID/confirmation.

 

He has a selection of Hell Creek teeth.  They are all very small--ranging from below 1cm to just above 1cm in length.

 

1 - Troodontid -- not the clearest image, but they seem to have distinctive denticles which are common in troodontid teeth? I don't think Troodon is from Hell Creek, but I see online it says Troodontid teeth have been found there. Seller has a more precise location of Harding County, South Dakota for these.

 

2 - Sold as possible Richardoestia -- Again, not the best of pictures. But hopefully it's enough to get an idea. To me, these look like they're more than likely a reptile tooth? 

 

3 - Unknown, possibly a raptor? Again, not the best image, but hopefully it's enough. 

 

Many thanks--and sorry for the poor pics. Even if exact species can't be confirmed, any ideas or possibilities would be, as always, much appreciated

Size?

 

I've sent seller a message for a more exact size. I'll post it when I hear back.

[Troodon]

Also if you can get better photos try to.  The first group looks like Troodontids but the top one is questionable hard to see.  The one on the left might be pectinodon why size but think it a  cf Troodon formosus as well as the one on the right.

You might ask for better photos. As a buyer don't be afraid to ask for that. 

[FF7_Yuffie]

I've requested some extra photos if possible along with the sizes. Ill post when I hear back. Nice to hear the top row are loooking good for Troodontid--I don't have any of them yet. 

 

Seller also emailed me this pair of teeth from Morrison foundation. They are 1.1 cm. He got them as juvenile allosaurus---but they seem more crocodile to me. The right one seems like it could have serrations--if that's a sign that it's anything more than croc? Could be premax teeth?

 

I've requested extra pics again. Showing the serrations.

Yeah, can't do much with the first photos.

Those bottom ones look like croc to me also. I’d stay away from most things that say they’re juvenile(more specifically big carnivorous dinosaurs.)

A better photo of the middle set -- the possible Richardoestia.

 

I'm leaning reptile, but I'll wait to hear from someone who knows more than me.  Biggest is 1.4 cm. Would the different coloration of the white one mean anything--different species or different section of Hell Creek?

Last photo are better the top one looks "cf Richardoestesia but want to see the other side.  One one the right still looks croc.  Need closer photos both sides on the bottom left. 

 

Asks for closups of all these teeth both sides.  If he's trying to sell them

Despite troodon's comments, I think the Morrison teeth are crocs.  

[PaleoNoel]

I think all of the teeth being sold as Troodontid seem to be, Pectinodon or as Troodon said cf. Troodon formosus. At least 2 of the three in the Richardoestesia group seem to be (unsure about the one on the right, could be something else). In the third group the tooth on the left is probably indeterminate while the ridges on the one on the right would suggest Paronychodon to me. As for your Jurassic teeth I agree they are crocodile, I would guess Goniopholidae.
