mommabetts Posted November 23, 2008 Share Posted November 23, 2008 I Tracer, look at my tortuga very muerta, not goog lighting for pictures, but I think that the images are comprehensives. Plastron pieces are very close to the extant Caretta turtle (viva) Thanks for sharing photos. Link to comment Share on other sites More sharing options...

Plastron pieces are very close to the extant Caretta turtle (viva) MB, did you find this specimen? What an impressive find; I'm drooling over it! I'm wondering if the entoplastron is present and intact? As you probably already know, the entoplastron can be used to diagnose between the various genera of extant cheloniids, including Caretta. I am well versed in marine turtle anatomy, having dissected hundreds of dead stranded turtles to determine cause of death as part of a past job I had. I am familiar with the skeletal structures of Caretta caretta, Lepidochelys kempii, Eretmochelys imbricata, and Chelonia mydas. I agree with your determination of Caretta, but I'm just wondering if the entoplastron was salvaged to really nail it down to genus. Link to comment Share on other sites More sharing options...

Hi Pristiformes, I'm not expert in those animals, but I had young friends who are recovering turtle skeletons of dead mediterranean Caretta, and I did compare the bones.. Yes I rescued years ago this group of bones from a miocene road cut very near from home. Not skull nor sternum bones as epi or entoplastron, only the pieces you saw and some isolated bones as a cervical vertebrae and humerus? but I don't think I have the entoplastron. I must to finish it and donate it to the museum. In all case, very few reports of marine turtles are describeds in my country. I will see the other bones remains I have in order to see that you ask. Nice to meet an expert like you. http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...

Nice to meet an expert like you. Not an expert, and not even really a specialist (anymore), as it no longer part of my job, although I still work in the biological sciences. I'm more of a generalist nowadays, except for anything to do with extant sawfishes (elasmobranchiomorphi: Pristiformes: Pristidae) of the western central Atlantic, which I have been studying for a little while. Anyway, neat loggerhead! Link to comment Share on other sites More sharing options...

Pristiformes Posted November 24, 2008 Share Posted November 24, 2008 don't look if you don't like barnacles!la tortuga muerta, verdad. The barnacles are Chelonibia sp. (either C. caretta or C. patula), a genus that is only found on marine turtles. Link to comment Share on other sites More sharing options...

screweduptexan Posted November 25, 2008 Share Posted November 25, 2008 Tartar Sauce! Sorry tracer, the whole "barnacles" comment made me think Spongebob. Yes, I love Spongebob and it is the ONLY cartoon I will watch. I know, I am a little too old for such childish things... I can't come up with anything clever enough for my signature...yet.

tracer Posted November 25, 2008 Author Share Posted November 25, 2008 see, that's the thing about this place. you can post a really gross photo of a long-dead sea turtle, and half the people will become technically interested in related minutiae, half the people will get very hungry, and the remaining half of the people will be reminded of children's cartoons. i think that pretty much sums up what our exalted leader has created here.

tracer Posted November 25, 2008 Author Share Posted November 25, 2008 sponge bob does kind of grow on you though. too bad i had to go through those incessant barney episodes for a couple of years, though. but lest the hate mail commence, i'm not knocking dinosaurs in general..

tracer Posted November 25, 2008 Author Share Posted November 25, 2008 you might think that this is a space where i accidentally double-clicked the "post" button and posted the same thing twice and am now editing the second one in an attempt to not be perceived as a fool. that would be incorrect. this post is a placeholder which i intend to come back and use to say something after someone else says something but make it look like i said it before they said it so as to appear precognitive. but as long as i'm here - hey, what about that xenolith... this would be where a piece of schist about a billion years ago decided to take itself for granite.

Auspex Posted November 25, 2008 Share Posted November 25, 2008 this would be where a piece of schist about a billion years ago decided to take itself for granite.
