Also got his little fella yesterday.

Kem Kem beds also.

 

Rooted premaxillary tooth of a Noasaurid??

 

Resembles the teeth published for the Madagascar Noasaurid Masiakasaurus knopfleri.

 

@Troodon, what are your thoughts?

Pretty little thing. Nice specimen  

[Tidgy's Dad]

Can't help, but that's a very unusual and attractive specimen. 

[hxmendoza]

Already have a few of these Kem Kem Abelisaur teeth. But this one is one of my favorites due to color and preservation. Just about pristine.

Nice new teeth! 

[Tidgy's Dad]

Yes, the colour is wonderful. 

Great tooth, anyway. 

[Troodon]

That rooted tooth is awesome,  pure guess work on the ID.   I see elements of both a Noasaurid and Abelsaurid.  The serrations look a lot closer to this premax Abelsaurid.  Any chances it could be premax positional one of the outside teeth with some curvature.  Crown is plump like this one.  Masiakasaurus hooked teeth have fine serrations, compressed with striations.  Having said that I have no idea what Deltadromeus teeth look like in these positions.  Call it a Abelisauroidea and get the best of both.  Cool tooth regardless.

Thanks @Troodon. When our Dinosaur curator, Joe Sertich, gets back from the Kirkland Formation in a few weeks, I’ll try to remember to take him the tooth and see if he can give me an opinion. He was involved in the discovery and describing of Masiakasaurus. I’ll keep all of you posted whenever that happens as to what he says.

 

How about I label it as:

 

Theropoda sp. indeterminate

aff. Noasauridae, and aff. Abelisauridae

?

[Troodon]

I think that is all you can do, have an eraser handy.

Again we have so little information on the morphology of these positional teeth its hard to make a call.  Masiakasaurus might be a unique type of jaw or typical of other Noasaurids like Deltadromeus.   Need answers tired of guessing...

[hxmendoza]

Thanks @Troodon, @Tidgy's Dad, @Bone guy, and @Jaimin013. 

 

I’m pretty thrilled with these new finds. 

[hxmendoza]

Oh, and I was also gifted this really nice Grallator footprint from Massachusetts yesterday.

You lucky chap! 

What a splendid gift. 

[-Andy-]

You are on a roll Henry!

 

The cf. Dromaeosaurid tooth and the rooted Noasaurid/Abelisaurid are awesome

[Troodon]

Very nice gift about the size of my hand?  Yep on a roll....

[hxmendoza]

@Troodon, yep, footprint is six inches in length.

thanks.

 

Thanks @-Andy-, and @Tidgy's Dad.

Nice, I hope we see a paper that describes this morphology sooner than later.   If its anything other than a Dromaeosaurid I give up.  Its classic.

 

Wanted to add that I went through about 100 or so Kem Kem small 5mm to 1.5cm theropod teeth yesterday, and only found this one tooth which has all the classic Dromaeosaur features that I posted above. And there were only 5 other small theropod teeth that had some of the features, but were more along the lines of problematical potential dromaeosaurs or indeterminate coelurosaur-like teeth, like have been posted here on TFF in the past by various other members.

The vast majority of the rest of the small teeth were Abelisauridae teeth. 

 

So this would mean that only about 1% of all very small Kem Kem theropod teeth are true dromaeosaurid teeth.

Here is a published photo of a mesial mandibular tooth from Masiakasaurus. Just for comparison and fun’s sake. Several similarities, though noteably my tooth lacks the vertical sulci or grooves seen on the lingual surface of the Masiakasaurus tooth.

What a gift stunning, the best gift I have had from Mrs Rico is also a Grallator footprint from France.

you got a very lovely collection indeed.

Nice one. Would you consider letting an experienced person fill the cracks? Just curious.

Thanks Ludwigia, but I do my own prepping and restorations. I have lots of experience doing it.
