So this was one of my first fossil finds from last winter on the Oregon Coast and I still need help identifying it further. It was tossed up on the rocky shoreline one day after a winter storm in the Stonefield Beach State Rec area (Central Oregon Coast).
I've sent photos to the Burke Museum's ID dept along with a few other museums that's offer opinions on fossils based on photo's and they've all said its definitely a rib, and but the debate is now between a Baleen/Whalebone or the Steller's Sea Cow. I've gotten mixed opinions from several museum experts but I would like to know or see if anyone else has come across ones like this on here and maybe has a more definitive answer.
Thank you for taking a look!
