Unknown Greens Mill Run Baleen Whale Skull Fragment

[fossil_lover_2277]

A while back I collected several pieces of sizeable whale bone from Greens Mill Run and was able to ID them as to specific skeletal element (several were ribs, verts, mandibles, etc.). However, this one piece is fairly sizeable and has a distinct shape (it is worn down some), pretty sure it’s part of a skull, but can’t figure it out. Any whale experts out there think they might can help? It’s from the Yorktown formation, and even though Greens Mill Run cuts through other formations, this one came from a section of the creek with Pliocene exposures and the other whale bones I was able to ID, so pretty sure it’s a Pliocene baleen whale.

fragment of a maxilla, premaxilla, mandible, or possibly even a bit of frontal or vomer of a baleen whale - impossible to identify further.

Thanks!! Was curious to know how much could be discerned from a worn but somewhat distinctive looking fragment like that
