luvmymushpups Posted July 27, 2023 Share Posted July 27, 2023 I found this in the banks of the Yukon River in Alaska yesterday. this spring it flooded and 20ish feet of riverbank was washed away. this was in the washed-out area. it seems to be hard like petrified. At first i thought it was part of an antler but asking around here people did not think it was from a moose because it was to flat and has a knob and not the right shape. so maybe another horned mammal or a bone. Any ideas? it is hard and cannot scratch it it is 7 inches long and 4 inches at the widest part Link to comment Share on other sites More sharing options...
Mahnmut Posted July 27, 2023 Share Posted July 27, 2023 Hello and welcome to the forum! This looks like the proximal end of an artiodactyls jawbone. Even-toed ungulates like bison, cattle or elk.

digit Posted July 27, 2023 Share Posted July 27, 2023 Yup. I think he's got it. Here is an elk and a bison jaw bone for comparison: Elk: Bison: Cheers. -Ken 3 1 Link to comment Share on other sites More sharing options...
Mahnmut Posted July 27, 2023 Share Posted July 27, 2023 Looking at the pointy end of the coronoid process (upper left in the reference pics) I think we can narrow it down to bovid.

Mark Kmiecik Posted July 27, 2023 Share Posted July 27, 2023 Could it be moose jaw? Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
luvmymushpups Posted July 28, 2023 Author Share Posted July 28, 2023 thanks for the replies, i can see now how it is a jaw bone. i am thinking moose? Also in the reginal area are caribou, dahl sheep, mountain goat, bison and musk ox. Link to comment Share on other sites More sharing options...
Mahnmut Posted July 28, 2023 Share Posted July 28, 2023 If you compare it to the top left corner of the references digit posted, the more pointed and less rounded end of the coronoid process makes me tend to call it a bovid, thats Bison, cattle and relatives. If you are sure its mineralised, thus probably old, that would leave Bison Sp..
