North Carolina Pliocene Bird Bone

Recommended Posts

I found this bone today in Edgecombe County North Carolina on the Tar River, upper Yorktown Formation, Rushmere member. The area is well known for Chesapectens along with other bivalves and gastropods. 

 

I looked at the Smithsonian publication,  Geology and Paleontology of the Lee Creek Mine, North Carolina, III. Miocene and Pliocene Birds from the Lee Creek Mine, North Carolina. Storrs L. Olson and Pamela C. Rasmussen. Issued May 11, 2001. After searching the many plates I found one that is a pretty good match. The proximal end of right ulna of Morus peninsularis. a Gannet. I am looking for your opinions on this. @Auspex It is plate 14 page 333. I would love to have this positively I.D.'d. 

 

It was found in the formation, partially exposed and 2 pieces. They fit together well. Overall length is 144.4 mm or 5.68 inch.

Storrs Olson, the Smithsonian avian fossil expert, identified an ulna I found as a gannet as well.  Said they are fairly commonly found.  Evidently there were more species of gannet in the late Miocene and Pliocene (wikipedia).

I think you have the right of it with Morus sp. The similar Cormorant ulna is smaller, with variations on the theme.

Pelicaniformes are cool 'cuz their ulnas show the quill knobs so well.

 

EDIT: What is its thickness, mid-shaft?
