Calvert Cliffs Bird Bone

I found this fossil bird bone recently while fossil collecting along Calvert Cliffs (Maryland Miocene).  I collected the bone directly from the fossil layer it was in.  I believe it is a Metacarpal bone from the wing region.  Fairly small measuring at approximately 13/16ths of an inch long.  Can't believe the thin section stayed intact while sifting in my screen.

Any ideas as to species would be appreciated.

Excellent find, Daryl.  I can't tell you the type of bird, but the bone is called a carpometacarpus in birds.  It is a pile of fused bones from the wing.

Thanks JP.  I knew there was something wrong with the name I gave it but couldn't figure it out.

Hey @cowsharks - I've been in contact with John Nance from CMM, and put him in touch with a good paleornithologist - N. Adam Smith at Clemson. Nice carpometacarpus!

Thanks Bobby.  John sent Adam a pic and he replied that "it is likely from a Passerine but it would be difficult to get down to Genus or species."  An initial review of the bird material at the Calvert Marine museum didn't reveal any similar bones, so it might be important to their collection.

 

Thanks for the tag-team effort!
