Large Bird Bone And Maybe The Walrus's Rib?

[cowgirlfossils]

So I found this rib next to the possible "Pliocene walrus Valenictus chulavistensis" as identified by Bobby.

Thinking the same animal?

The bird bone was about 20' above so in a different time period. Maybe Pleistocene. Picture not very clear as it is extremely fragile and still surrounded by sand. I'll try to stabilize it a little better before removing the rest of the sand.

The bird bone is approx. 1 1/2" across the end and 1" across the bone. Don't have all the pieces so not sure how long it was.

Funny..folks say "look how much has been lost to the dozier" But, none of this ever would of been found had it not been for the mining.

The second to last pic is bovine!

That bird bone appears large: use as much consolidant glue as you can on the specimen to keep it from getting any further damage. The end of the bone will be critical in getting it identified. If it's as large as I think, and based upon how thin the cortex is, this is likely an albatross or a bony toothed bird (Pelagornis).

Love it! Thank you! Are these bones far and few between? Is it the same as the Pelagornis sandersi or related to, like I find on the internet?

Going back for another look this eve.

How about the rib? Any ideas?

[Boesse]

Yes! Pelagornithids are very rare in North America. You can imagine why, just looking at how thin the bone is. Probably not Pelagornis sandersi, since that species is ~20 million years older or more and from the Atlantic. There's only one named pelagornithid from the west coast, and it's middle-late Miocene in age - Pelagornis orri.

Probably not possible to identify the rib, unfortunately.

I thought the sandersi was to old..Thank you for all your help!
