PaleoMexico Posted May 30, 2016 Share Posted May 30, 2016 (edited) 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. Edited June 14, 2016 by Fossildude19 Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 30, 2016 Share Posted May 30, 2016 I'm afraid that this looks like flowstone, or limestone - not bone.

Wendell Ricketts Posted May 30, 2016 Share Posted May 30, 2016 Ditto-heading. Nothing there looks like bone to me, either. _________________________________ Wendell Ricketts Fossil News: The Journal of Avocational Paleontology http://fossilnews.org https://twitter.com/Fossil_News The "InvertebrateMe" blog http://invertebrateme.wordpress.com Link to comment Share on other sites More sharing options...
PaleoMexico Posted May 30, 2016 Author Share Posted May 30, 2016 I uploaded a new photo, it is clearly a bone Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 30, 2016 Share Posted May 30, 2016 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.

JohnJ Posted May 30, 2016 Share Posted May 30, 2016 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.

Auspex Posted May 31, 2016 Share Posted May 31, 2016 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.

finderskeepers Posted June 2, 2016 Share Posted June 2, 2016 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. Link to comment Share on other sites More sharing options...

PaleoMexico Posted June 7, 2016 Author Share Posted June 7, 2016 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 Link to comment Share on other sites More sharing options...
JohnJ Posted June 7, 2016 Share Posted June 7, 2016 Do you have photos from the 'end' perspective? The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
PaleoMexico Posted June 7, 2016 Author Share Posted June 7, 2016 Do you have photos from the 'end' perspective? if you check the post # 11, the first photo is the "end" perspective. Link to comment Share on other sites More sharing options...
Scylla Posted June 7, 2016 Share Posted June 7, 2016 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.

PaleoMexico Posted June 14, 2016 Author Share Posted June 14, 2016 (edited) 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.

CraigHyatt Posted June 14, 2016 Share Posted June 14, 2016 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?

CraigHyatt Posted June 14, 2016 Share Posted June 14, 2016 Here's a list of fossil bird genera and some proto birds.
