Missouri elk?

Recommended Posts

Awolartist

 hello! I recently acquired this fossil jaw bone, it was stated that it was an elk fossil found in the Missouri River... I was wondering if anyone could give me an exact species? Also, the person unfortunately went sloppy wild with some 50/50 glue and it's smeared on the jaw bone and even covering some of the chewing surfaces of the teeth. Any hints on the best way to remove some of it?

Im heading more toward the Bison/Bovid side of this ID.

Me too. Compare with this image of a bison jaw found online:

@Harry Pristis is THE expert on bones in general, so he will surely be able to point you in the right direction.

It is bovid, as caldigger suggested.  Bison is not an unreasonable guess.  It is from a youngish individual, judging from the mix of deciduous and  newly-erupted permanent teeth. 

 

If you are lucky, the glue will be acetone soluble.  If  "50/50 glue" is dilute white glue, you've got a problem which solvents won't help.  Cured white glue can be softened by heat (e.g. a hair-dryer), then rubbed with a fingertip into rubbery crumbs.  Use dental tools to pick and scrape away whatever glue you can.  Good results cannot be guaranteed, of course.  Do a search of TFF for discussions of white glue removal.

Thank you so much! I'll try that. Bison molars I have are so much bigger than this guy, so it makes sense if it's juvenile. Was there such a thing as a prehistoric elk in the area?

Elk in the Missouri River drainage?  Very likely.  Your jaw may be Bison occicentalis, the extant bison.  There are other, earlier species which were larger.

Some of the teeth have isolated stylids, but they are too long for elk.

I begun trying to wipe off some of the errant glue with warm water and realized the entire jaw - bone, teeth, everything is *completely* coated in glue. It seems to be coming off with water and a lot of work... but you can see how bad it is below.  Ugh. Wish me luck.  :/

Wow, you weren't kidding about the glue! Should look great when you're done though.
