old bones Posted December 11, 2016 Share Posted December 11, 2016 A few weeks ago I submitted a request for ID on a couple of tiny bones from TFF member Sacha's Merritt Island Pleistocene matrix. http:// Small Pleistocene bone for ID - Fossil ID - The Fossil Forum The help that I received was based on the limited photos that I supplied. Lateral views alone just don't cut it! I was not satisfied with 'mouse', so I 'dug' a little deeper. I decided to re-photograph a few of the odd little bones in different aspects this time. Duh... my results really do illustrate the importance of showing the 'ends' of a bone. It was very obvious from my new photos that these are vertebrae. Then came hours of research and many PDF downloads. Turns out that these cool little bones are autotomous lizard caudal vertebrae. There seem to be at least two kinds in the matrix possibly representing different species (or positions in the tail). I have included some of the links to helpful papers on the subject. http://www.scielo.br/pdf/aabc/v87n1/0001-3765-aabc-201520130298.pdf http://The Anatomy and Histology of Caudal Autotomy and Regeneration in Lizards (PDF Download Available) http://Lizard Caudal Vertebrae on JSTOR 13 Link to comment Share on other sites More sharing options...
digit Posted December 11, 2016 Share Posted December 11, 2016 Way to keep at it and search out the correct ID. I'd have never suspected lizard caudal verts (possibly Anolis to match some of the jaws found in that micro matrix?) Cheers. -Ken Link to comment Share on other sites More sharing options...

I do think that the long narrow ones probably are anoles. There are just so many of their jaws in this matrix. 13 hours ago, Sacha said: Julianna, I don't have words sufficient to express my amazement at the work that you do!

There are just so many of their jaws in this matrix. Occam's Razor would seem to indicate that that would be the most likely candidate (unless proven otherwise). The "frog toe" micro-matrix continues to give up wonderful prizes (and mysteries) to those who seek. Thanks for the update--always wonderful to see what you are finding. Cheers. -Ken Link to comment Share on other sites More sharing options...

Thanks, Jeff I do have a lot of my limited space devoted to my micros... but whose complaining! Seriously, I am glad that my fossils take up so little room... Still, I would find room for a mammoth tooth or sloth legbone, or... well, you get the idea! 4 hours ago, PFOOLEY said: Just awesome!...keep shinin' that light! Thank you so much.
