Large fossil possibly whale bone fragment

[Dnicewave]

Large fragment found in Myrtle Beach, seems to straight to be a rounded rib section but because of its size I think it may be a part of a whale.

Chunk-o-therium.

 

I don't think this can be ID'd further than Chunk of bone. Probably Mammal.

Could be cetacean, but I don't think it's rib bone.

It's about the right size and shape to be a section of baleen whale jaw.

Except the texture seems strange to me. The size and shape are not enough to tell what it is. I don’t see any alveoli.

It is close....  The contours of the broken end is similar and the baleen would lay in a groove on top,  but I have some fragments of whale jaw (maybe close to the tip) where the baleen slot seems missing.

That looks to me more like a type of igneous rock than a bone. I might be wrong though.

Looks can be deceptive.  I hunt Bone Valley and the Peace River in South Central Florida.  We have never had any source of magma.

This from the 8 year old link above. When I found it, I did not know what a Baleen whale Jaw looked like. This comment from Robert Boessenecker, one of the foremost whale experts in the world.  It is one of the fantastic characteristics of TFF that we can attract experts.
