Dinosaur Tooth?

Recommended Posts

megabass22

Recently I was in one of those rock shops (that sells minerals and fossils and stuff), there was a bunch of cool things, but i only bought this little tooth. I have no idea what it is (a sign simply said "dinosaur teeth", but i'm not sure about that), and no idea from where it is or how old it is, so that's why i'm asking here. Normally I would be able to identify it myself, but as you will be able to see in the pictures it has an unusual feature.

View of the "unusual feature", which almost appears to have lead to some kind of secondary "mini-root" (though it probably isn't, and yes, this photo is blurry but you can probably see what i'm talking about):

The fossil measures 2,6 cm (just a tiny bit more than 1 inch) in length if that helps.

Sorry I cannot make out your unusual feature with the image provided. There is no way to provide you the information asked other than saying it appears like a partial Dino tooth since there are serrations. There are too many similarities with teeth that unless you know the location where it was found trying to ID it is difficult. The color may indicate its from morocco but its pure speculation. Did this dealer sell Moroccan material?

Now you have me questioning my first call. Can you take some additional pictures.

What kind of pictures do you need?

The bottom of the tooth is broken. It broke in a non-straight-line pattern, so it appears to have two roots, but it does not have any part of the root.

So it did not have two roots? It certainly looks like something like that, or is it my newbie knowledge speaking now? Obviously the root(s?) and the top are broken off. Any clues on an ID?

Can you take some additional pictures so we can see different angles. Also are there any serrations on the tooth? Dinosaur teeth do not have two roots.

I do know that dinosaur teeth only possess 1 root. Here are a few angles :

It could have once had serrations ( it almost appears so ), but in any case they are gone now, or really, really small.

Thank you, good pictures. I don't think its a dinosaur tooth and looking at the edges it does not appear to have had serrations. I don't know what it is but if it has two roots it may be marine and possibly a whale tooth.

Hmmm...

The whale teeth i have seen seem more robust, and with 1 single root aswell? So i'm still clueless.

I'm clueless but cetaceans can have two roots.

Well thanks for your help anyway :)

Hopefully someone else can help me narrow it down, this is quite exciting for me :)

I have yet to see an image of this tooth that actually shows it to have had two roots, so we are casting a large net here.

But if you look at the bottom here: https://farm3.staticflickr.com/2901/14492095649_a0b1921556.jpg

You can see the big part that would have led to the root, and a smaller "outgrowth" leading into the same direction.

This Side-view shows it quite well too: https://farm4.staticflickr.com/3892/14682665662_079f034773.jpg

There is what appears to be enamel between the root and the "outgrowth".

I agree with megabass there seems to be an outgrowth since there is enamel between the two. Not sure however if the top one is a root.

It appears to be too small to have supported a root, but It's something.

This is indeed an odd morphology, but neither includes any un-enameled bone; there is no root physically present, leaving only extrapolation. I am loathe to take for granted that this tooth had a double root.

I don't think it had either but, something odd was present, that made it hard for me to identify it.

The photos are actually quite confusing. But thinking we might have something from Morocco here I suspect you have a fragment of an Onchopristis numidus tooth. It's a sawfish. This would explain the lack of serrations, I think what you are seeing as 2 roots MIGHT be the broken barb these teeth have at the tip. Have a look at this tooth on Google and let us know what you think.

Yes, i believe you are right! Thank you!

The specimen would then include the section above the barb, but not the tip. I have been wanting a fossil of this species for some time (to go with my Spinosaurus tooth), so even if It's not a dinosaur tooth, I'm happy :)

Thanks to everyone that helped :)
