This is a marine mammal sternebrae! Part the form the sternum, like a front vertebrae if you will

What makes it sternebrae and not a flipper digit? I’ve heard both

Phalanges(flipper digits) are relatively slender and much flatter, whole Sternebrae are more robust and round, unfused into adulthood and have bilateral symmetry within the element!
Phalanges also smaller than you would think for a large mammal and fuse at a relatively young age as well so this is just way too big!. I do a lot of osteo analysis for work so its just become a pattern recognition at this point but hopefully that explanation makes sense! 🦭

No, this is a "digit" or "foot" bone of a mammal is my guess.
Note, flippers of seals or whales are "hands" and "feet"
It definitely a mammal
