Sinopaleus Posted March 22, 2013 Author Share Posted March 22, 2013 (edited) A hash plate of Devonian fish... Including Sarcopterygians and Placoderms. The shield plates mainly belong to Bothriolepis sinensis, but there is a fairly complete placoderm preserved along side with a giant 4-cm sarcopterygian (lobe-finned fish) tooth. I think the placoderm is Bothriolepis sinensis. Psarolepis romei & Bothriolepis sinensis (?) Early Devonian B. sinensis Zone, Qujing, Yunnan, China IMG_8838.JPG IMG_8839.JPG IMG_8843.JPG IMG_8844.JPG UPDATE: The fish fang I.D has been confidently narrowed down to an Onychodontid's tooth, most possibly a parasymphyseal fang of the ancestor for ray-finned and lobe-finned fish, Psarolepis romei. " In 1999 Zhu et al. were unable to locate Psarolepis in the cladogram because they did not know if it was the most primitive lobed-finned fish or the most primitive bony fish." - Wikipedia "Psarolepis had teeth at the very front of the snout with large fangs on the tooth plate." - Wikipedia http://en.wikipedia.org/wiki/Psarolepis Edited March 22, 2013 by Sinopaleus Link to comment Share on other sites More sharing options...

Sinopaleus Posted March 24, 2013 Author Share Posted March 24, 2013 At the sill of a doorway of evolution...very cool specimen! Auspex, you might like what's comin! This bird's egg is the size of a pigeon egg, about 1 and a half inches in length. The majority of the shell is still there, and you can still see the pores on the eggshells. Currently waiting back to hear from a professor regarding the egg's species and what bird's it was. My nice wooden fossil ruler is gone.. so I put a pen in for a temporary size comparison UNDET Bird's Egg Miocene Hezheng fauna, Hezheng, Gansu, China Link to comment Share on other sites More sharing options...
Sinopaleus Posted March 24, 2013 Author Share Posted March 24, 2013 This is one helluva devil's toenail (no pun intended )! It is 4 and a half inches in length, and ~3 inches in width. I compared it with a typical Gryphea from the U.S... for a size reference I'm not sure as to what species this Gryphea is, but the ornamentation on the shell is different from the other Gryphea.

Auspex Posted March 24, 2013 Share Posted March 24, 2013 Auspex, you might like what's comin! ... You might be right! This is a fantastic fossil!

Auspex Posted March 25, 2013 Share Posted March 25, 2013 ...Do you possibly know whose egg this was? No, there is no way to know, other than to say that it is of similar size and shape as one laid by a modern species. Eggs are something like ichnofossils, except that they are actual organic remains instead of traces. Of all the fossil eggs that I have, only the pair from the Oligocene have a tentative association, and then only because the species of fossil bird from the site that left enough bones to composite and compare to modern was rather like a Limpkin, and the eggs are rather like a Limpkin's eggs, so.... (My Oligocene specimens are two of the group that were studied for the paper drawing the Limpkin conclusion).

Sinopaleus Posted March 25, 2013 Author Share Posted March 25, 2013 This is an unprepared concretion containing an ammonite. Apparently it was found in a river at the base of the Himalayas. The ammonite might be Kossmatia, but I am not sure. Don't wish to cause any political tension, so I'm not going to be too descriptive on the location... So yeah, the ammonite is from the Tibetan regions. Kossmatia (?) sp Middle Jurassic Himalaya Mtns, Tibet, _______ Link to comment Share on other sites More sharing options...

Sinopaleus Posted March 25, 2013 Author Share Posted March 25, 2013 This is a right cheek tooth from the giant true horse, E. eisenmannae. It has the longest known skull, with it's holotype skull measuring 625 mm, longer than that of the largest known horse, E. enormis. E. eisenmannae is a transitional horse between the plesippine and the allohippine. Equus eisenmannae Pleistocene Longdan, Gansu, China Link to comment Share on other sites More sharing options...

Sinopaleus Posted April 28, 2013 Author Share Posted April 28, 2013 A freaky brain fossil! I'm planning to learn a bit more about Camelidae brains so I can interpret some of the evolutionary changes that has occurred over the past 35 million years on their brains. Maybe I can learn some interesting things, like maybe Poebrotherium used their smelling sense more than their hearing while modern Camels use their hearing more than their smelling. This will be a very interesting specimen to learn from! Poebrotherium franki Middle Eocene Indian Creek Formation, Lusk, Wyoming, USA Link to comment Share on other sites More sharing options...
