OregonFossil Posted April 3, 2022 Share Posted April 3, 2022 (edited) Here is a series of four images of what I believe to be a bone. Don't know what kind of bone, but it appears to be hollow. In the paper: Giant Late Eocene Marine Birds (PELECANIFORMES:pelagornithidade) from NorthWestern Oregon by James L. Goedert, he states the abstract of this paper: "ABsTRACr-Fossil bird bones from the late Eocene Keasey Formation and the latest Eocene Pittsburg Bluff Formation in northwestern Oregon are the earliest records of the pelecaniform family Pelagornithidae for the Pacific Basin. These fossils also represent late Eocene records of the family from the Northern Hemisphere, the second late Eocene record worldwide, and indicate animals were among the largest of flying birds. Unfortunately, the fragmentary condition of these fossils and the currently state of pelagornithid systematics prevents the assignment of these specimens to new species at this time." If this is, I will forward to folks working on this issue (Goedert was an associate of the Natural History Museum of LA). I don't want to take the chance of damage of further matix removal. Images are of the object that is 6.7mm x 6.5mm located from the lower portion of the Pittsburg Bluff Formation between Pittsburg and Mist, Oregon. Anyone have any idea of what this is? I've been examining the PBF "fall out" along the road for about two years and have never seen anything like this specimen. Am forwarding the same images to the Paleo Dept. at Oregon State. I've included an image (Marked with a red T for where the specimen was fund under the top matrix cover, and an image of the collection location. Red T is where specimen was found after removing matrix.

Oregon1955 Posted April 3, 2022 Share Posted April 3, 2022 Oregonfossil, Bird bone from the Pittsburgh Bluff Fm. would be super rare and exciting. I'm anxiously awaiting an opinion from the forum's gurus. I'm not that guy. Goedert's the guy but have no idea if he's a member here. I will say it looks a little shell-like to my eyes, perhaps a bit of gastropod? On other hand, I'm looking at a picture on a phone and have never seen a bone from this formation so here's hoping you're right. You're doing good work and I look forward to more posts.

Mike I've collected about 250 Gastropods (25 species so far, some of the rare ones) from the PBF and have everything from molds, casts, and shells. None of them have ever looked like this IMHO. You should visit PBF, lots of fun, however, be aware that between that road and the log trucks @ 55MPH+ (they)swerve away when they can safely) and you is just that white line:).

Auspex Posted April 4, 2022 Share Posted April 4, 2022 What of it I can see appears to be the proximal portion of an avian coracoid. Sweet find!

OregonFossil Posted April 4, 2022 Author Share Posted April 4, 2022 Thank you so much. I think I've found a local professor who works in this area. I will gift it to him if he wants to add it to his research. Link to comment Share on other sites More sharing options...
jpc Posted April 4, 2022 Share Posted April 4, 2022 I am not familiar with shells nor bones from this formation, but the structure of this looks more shellish to me. 1 Link to comment Share on other sites More sharing options...

I see what you're saying. What we can see could be the broken-off 'tail-end' of a gastropod... I'd really like to see it prepped-out further.

OregonFossil Posted April 6, 2022 Author Share Posted April 6, 2022 (edited) Ok, I put on my big boy pants, and a hour and half later this is the series of images. Taken on a 5 mp camera - they look good on my 27" when about a quarter to half screen size. Most of the fossils that have calcium shells are very crumbly on this matrix, this is very strong - feels like fresh shell or more likely bone I think. The layer of the Pittsburg Bluff formation where I found this might be an alluvial fan of a river that emptied into the ocean. I took as many orientations as I feel comfortable doing. Await the Judges decisions:). Made the files jpg's instead of tif's to show in the post. Edited April 6, 2022 by OregonFossil 1 Link to comment Share on other sites More sharing options...

Fossildude19 Posted April 6, 2022 Share Posted April 6, 2022 This looks more shell like than bone like, to me. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Auspex Posted April 6, 2022 Share Posted April 6, 2022 These new pictures rule out bird bone, or bone of any type, for that matter. The striations and prismatic structure are consistent with shell material.
