Bone of Large bird of México


PaleoMexico

Recommended Posts

What opinion do you have, is a large bird jaw or is another structure? It was found in tufa calcareous with river bivalves of the late Pliocene of north of Mexico.

I'm afraid that this looks like flowstone, or limestone - not bone.

I am not compelled by the images to believe it is bone.

The pictures to the right and left look like bone, but the center picture does not clearly look like bone to me.

Can you take higher resolution pictures of the broken end, and some close ups of what you are seeing as bone texture?

Perhaps the photo quality does not allow for detail seen in hand to translate properly onto a computer screen. :)

I uploaded a new photo, it is clearly a bone

The glare from the flash has washed out the detail in your middle image. I can see that it is bone, but adding additional images will be helpful.

Better image, but I cannot quite orient it in relation to the other views...

If it is supposed to be a proximal avian upper mandible, I cannot reconcile its increasing thickness toward the distal.

Pictures of the broken end would be more helpful. :)

Have you found any other bones at this Pliocene location?

I think it is fossil bone. Of what I'm not sure but if that was in my collection I'd take it to a vertebrate paleontologist.

Straight-on end views could help me orient things.

Hi all!! Retaking the discussion of my previous post big bird (Pliocene) Mexico. I upload more photos with the cleanest material. It will be a part of jaw? What do you think?

The material is not associated with other fossils. Only the calcareous tufa has bivalve Indet. from Conchos-San Fernando river.

regards

Do you have photos from the 'end' perspective?

Do you have photos from the 'end' perspective?

if you check the post # 11, the first photo is

the "end" perspective.

The better picture look more bone-like. I cant tell what they are from though. When they are asking for pictures from the end they mean to get a picture in the coronal, sagittal and transverse plane. Preferably front/back, right/left, and top/bottom.

I have a hypothesis, my idea is that it is a humerus of a bird, what you think?

The first photo is anterior view of the humerus

The second photo is ventral view of the humerus.
*I remind you that this bone was found in calcareous tuff.
Regards.

Can you give the approximate location such as the state in Mexico?

Edit: How did you place the age of the specimen as Late Pleistocene? Also, can you provide the dimensions of the specimen?

Info: Craig Hyatt, retired software/electrical engineer

Experience: Beginner, fossil hunting less than a year

Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert

Formation: Escondido, Marine, Upper Cretaceous

Materials: Sandstone, Mudstone, Shale, Chert, Chalk

Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus

Here's a list of fossil bird genera and some proto birds. Perhaps you can compare your specimen to the photos.

Thanks CraigHystt, Regards!!

If you can say the size of your specimen, I will help you search for a match.
