Dinosaur Tooth?

[mdegraff]

Hi there! Found this piece this weekend and initial research makes me think this night be a dinosaur tooth but am looking for expertise... Any thoughts? Thanks so much!

Yaay! Got the picture thing figured out! Here's one more.

Pictures are a bit dark, I took the liberty of cropping and lightening the contrast a bit.

Regards,

Thanks, Tim! Those look great

Does not look like a dinosaur tooth

[Taogan]

Can't see it as a dinosaur tooth, sorry.

[mdegraff]

Thanks Troodon and Taogan for your expertise. Any ideas what it could be if not Dino tooth? Given what appear to be striations and growth rings along outside w no apparent structure or rings shown on the inside on broken side, I suspected tooth first, but also wondered about horn antler or bone.. Could this be?

Here is another photo that sort of details that blunt side

This is a very strange piece. Im thinking more invertebrate or even petrified wood. Im very interested to see if this gets ID or not.

[Taogan]

My first impression was a plant stem, something like Calamites, but I can't be sure.

small chunk of Calamites, perhaps?

p.s. heh...Taogan beat me to it.

[Auspex]

Where was this found? If we could determine its age, we could maybe make some headway with an ID.

[prem]

I was hazarding a guess since her location is Wyoming that it was found locally. I also googled the fact that Wyoming is a major coal producer in the US. Put the two together and Calamites is probably a good guess.

[Auspex]

I think those coal beds are Paleocene-Eocene.

[mdegraff]

Hi all. This fossil was found a half an hour south of Pinedale, just south/west of the Wind River range.

I have no idea what this thing is, but if you ever get to Casper bring it by the Tate Museum and we will have a look in person, in the hand. The geology of an hour and half south of Pinedale... there's a lot of Eocene out there.

No Calamites in WY's coal deposits, which are indeed post Calamitic.

[jpc]

I have no idea what it is, but it is not a dino tooth nor a Calamites. All of Wyoming's coal is post-Calamites. If you ever get to Casper, bring it by the Tate Museum where I work and we'll give it a good look over and argue about what it is. These thiongs are mush easier to ID if you can see the actual specimen. The geology an hour and a half south of Pinedale is almost all Eocene. Is that an hour and a half on paved roads or county roads? South exactly or more SSE? or SSW?

[mdegraff]

I found the piece just about half an hour south of Pinedale, barely past the small town of Boulder, about a thousand yards from the main highway there. Found it on open ground, not very near to any smaller roads or two-tracks. So it sounds like the age of this area rules out calamites.. Some photos of Dino teeth look very similar to my eye, but I don't doubt that I could be missing some defining characteristics there.. Absolutely we could bring in this piece sometime, perhaps in the next month! Thanks for the mention!
