Unknown Pliocene Humerus?


Pool Man

Recommended Posts

Hello all,

Here's a broken little bone that I though belonged to a bird,due to it being very lightweight and mostly hollow.But I compared it to a recent humerus that was probably from a raccon at it seems very similar. This came from the upper clay layer here in north port,so possibly later pliocene in age.I also found the mirror image of this bone, but unfoutunatly its in (many)pieces,with alot missing.

The larger piece is 3 1/4" long

It's the right humerus from a large member of the family Recurvirostridae (Avocets and Stilts).

This guy would have been about 25% larger than an Am. Avocet. Sorry, I cannot identify the Genus.

Great find! :wub:

(If you had both humeri in association, I have to ask: you didn't leave any more of this bird "in situ", did you? )

Looks like Phalacrocorax.

There are similarities to Cormorant, but the ligamental furrow is so pronounced that it makes the bicipital crest and adjacent area seem like an "island". This feature is consistent with Recurvirostra.
