Calvert Cliffs - Miocene Bone [SOLVED: dolphin scapula]


HemiHunter

Recommended Posts

Found a bone fragment at the Calvert formation that I haven't seen before. It's fairly distinctive.  I'm wondering if there's enough of it to ID. Any thoughts?

The convoluted morphology makes me think pelvic bone fragment

I toyed with that too. The marine look of the texture made me shy away, but it may be.

Thanks, @Rockwood @darrow @FossilsAnonymous for taking a look. I think I have figured it out.  It looks like it could be part of a dolphin scapula, with the long piece being the acromion.  Here are some comparison images from Cozzi (https://www.sciencedirect.com/topics/veterinary-science-and-veterinary-medicine/first-metacarpal-bone).  What do you guys think? @sharkdoctor

Dolphins have weird scapulae.

Hi,

On first look I would have said zygomatic arch, but the scapula looks convincing. None of your fotos is the same orientation as the example pic, but yes.

Best regards,
