Auspex Posted November 10, 2015 Share Posted November 10, 2015 Is the skull of a bird or a reptile ? Skull? I do not see anything skull-like in these images.

Tanit Posted November 10, 2015 Author Share Posted November 10, 2015 Skull? I do not see anything skull-like in these images. For me, who is not a specialist , photo 1: skull and beak , photo 2: the palatal vault , photo 4 and 5: the orbits of the eyes Link to comment Share on other sites More sharing options...
Auspex Posted November 10, 2015 Share Posted November 10, 2015 These are suggestive shapes, at best. There are no details that a skull would show. For one thing, a skull is composed of several fused bones, and there is not even a hint of this.

jpc Posted November 12, 2015 Share Posted November 12, 2015 This one certainly looks like bone, but I don't think there is enough to ID it. When wefind thingslike this we jokingly call them 'chunkosaurs'. Link to comment Share on other sites More sharing options...
Tanit Posted November 12, 2015 Author Share Posted November 12, 2015 (edited) This one certainly looks like bone, but I don't think there is enough to ID it. When wefind thingslike this we jokingly call them 'chunkosaurs'. it's amazing. it's a complete piece in perfect condition , I do not understand why we could not identify it.

Troodon Posted November 12, 2015 Share Posted November 12, 2015 This item is far from being in perfect condition, its a partial bone, why it cannot be identified. Diagnostic features are needed to help in identification which this lacks. It's thickness may lead one to say it might be from a limb bone.

LordTrilobite Posted November 12, 2015 Share Posted November 12, 2015 It seems to have a certain symmetry though. Especially that concave side. Since it's very fragmentary it might be almost impossible to say what it is. But right now I wouldn't completely rule out the possibility of a skull piece. Though there don't appear to be any obvious sutures. Interesting piece. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Auspex Posted November 12, 2015 Share Posted November 12, 2015 it's amazing. it's a complete piece in perfect condition , I do not understand why we could not identify it. This is not correct; it is a heavily weathered fragment. How else would the cortical bone be missing, exposing the cancellous bone?

Tanit Posted November 12, 2015 Author Share Posted November 12, 2015 A question : are the red spots of blood ? Link to comment Share on other sites More sharing options...
LordTrilobite Posted November 12, 2015 Share Posted November 12, 2015 Blood doesn't stay red for very long. And it doesn't fossilise. When there's red on rocks or fossils it's generally an indication that there's iron in it. So what you're seeing is basically "rust".
