Bear skull piece- right? Confirmation needed on predator mammal skull


Jaybot

Recommended Posts

Hey everyone!

Recently I found this skull section, and after some research I am pretty sure it's bear.  Due to size, I have determined that it is too big for black bear, so I determined that it was brown bear.  That is, until I realized quite a few predators look similar... and now I'm not 100% sure on my Brown bear id. 

I'm hoping some of y'all can either confirm that it is brown bear- or if it is something else possibly.

Thank you so much in advance!

 

Found in 'Glacial' deposits of E Kansas

Measurements are in cm/mm

And here's why I hesitated on labeling it as brown bear:  (not suggesting in any way that these are possible id's)

Cave lion, notice the back where the eye socket is very similar to yours, (I am not saying it is cave lion, just a possibility)

Can't be Cave lion, their range does not reach to where this was found:

If  it was lion, it would be the American Lion.

Update:  This is in fact a Felidae braincase, likely belonging to Adelphailurus kansensis

That would be sensational, as far as wikipedia tells me there is only one specimen known, and though wiki is not the most reliable of sources I assume that means they are quite rare?

That fragment would be a paper of its own, especially as the holotype KUMVP 3462 is the front part of a skull lacking the back.

May I ask how you found that ID?

And what are you going to do with it?

Best regards,

J

Outside of Wikipedia, I have found mention of a few specimens, and I think one was found in Arizona if I remember correctly.

 

  The rarity of this genus/species is what’s making me hesitant labeling it as such.  I identified it to that genus by elimination of all other possibilities that I could think of (Homotherium, American Lion, Smilodon, Puma, etc). Characteristics and/or size led me to this genus.  If this ends up being Adelphailurus, I might loan to a local Institution for temporary research- we’ll see.  I’ll get in contact with the local expert soon.  
 

  If this is what I think, it indeed would be very neat to have a paper on it!
