Possible Cretaceous Osteoderms Found In Central Alberta Badlands. Please Help ID

[Backcountryhiker]

While hiking in the Central Alberta Badlands Near Toleman in Red Deer River Valley came across two pieces of fossilized matter that looked very different than most of the bone fragments I have encountered while on similar outings.  If I was to take a wild & uneducated guess I would say they look like they could be osteoderms? Any help to ID  these strange pieces would be greatly appreciated.

 

Thank you In advance.

Thats a beautiful area to collect.

 

The first one certainly has the features of an osteoderm with the keel and shape so its very possible to be one.  

The other specimen I think not, has some features of a herbivore jaw but to fragmented to be sure.
