Hello zooarchs.

I'm at an impasse with several bone pieces. 

They are definitely identifiable but I must be having a "bad bone week".....

They're just pieces, but if you have any ideas of what elements I should check that I may be not thinking about I'd appreciate it.

Context is a Paleoindian bison kill but I'm finding bits of elk and pronghorn. There could always be other 9,000 year old Wyoming beasties.

Thanks muchly,
