I'm going to say it is thin enough and squarish enough to be a nano. Better wait for other opinions though.

Doesn't look like Rex to me

Hi @lone5wolf117 this is likely to be nano rather than rex, the cross section also indicates this but you would need further info like serration density etc

Just to throw in more confusion, it looks Rex to me. Cool etchings!

Nice tooth even with the root damage apparent on the enamel. I would like to see a closer image of the base if possible. I do think it’s a Nanotyrannus tooth. The oval shape of the base has me a bit stymied though which is why a closer view may help in identifying this particular tooth.

Can you post straight in photos of this tooth.. the obtuse angles make it difficult to get a read on it.   Include the base.

So that's what caused it. I'm not sure I have encountered roots that were that hungry. :headscratch:

That's because You are not root food yet, give it time.:P

 

A long time I hope.:D

I rather think it's just that I have a gentler dental hygienist.

Roots do dissolve minerals as their feeding process, but enamel, this deeply I doubt.

Odd to be sure. I’ve noticed more than a few tyrannosaur teeth from Hell Creek that have exhibited this type of plant root damage. Not sure if it’s caused by pressure or some sort of damaging chemical reaction via contact with a certain type of plant? All these teeth exhibit the same sort of etching damage.

Believe it has to do with the acid in the roots which eats away at the enamel when it fossilizes. It’s pretty common in the Hell Creek because it was a a swampy environment.

The type of roots would make a big difference I guess. I can see something like these Monstera roots doing something on that scale.

This example of root etching is what I'm used to encountering.

Mhm yes I agree that they look fairly similar. Although I’m sure the severity varies by paleoecosystem. I’ve seen other dinosaur teeth with similar root etchings but none seem to compare to the Hell Creek.
