Petrified Wood Slabs
MarcoSr posted a topic in Member CollectionsI'm interested in petrified wood for the scientific value (wood where the cell structure is well preserved), for the aesthetic value (mineralized with vivid colors and crystal shapes), and for oddities (like fungus, insect borings etc.) contained in the wood. Below are three petrified wood slabs, from the United States, from my collection. The below individual slab pictures were taken with the slabs dry, indoors using my camera with flash. The close-up pictures were taken with my Dino-Lite digital microscope. If you want to see a lot more of the petrified wood pieces in m

Burrow cast in Chinle Formation
kgbudge posted a topic in Fossil IDTrace fossils aren't always as exciting, but I like the ones I've found. This looks like a burrow cast. From the "mottled member" of the Chinle Formation, Temple Mountain, San Rafael Swell, Utah, US. Posting also to check my identification. My references indicate that the mottled member at this locale is known to have lungfish burrows ... unless they're crustacean burrows. This one seems large for a crawdad (even a Triassic crawdad) but small for a lungfish.

Triassic Jaw Specimen, but what kind?
rkfrace posted a topic in Fossil IDHello all! Any insight on this unidentified fossil, from Eastern Arizona, Chinle Formation, would be deeply appreciated. I'm presuming it's a partial phytosaur jaw, but I really have no idea. Originally from a family who collects on their private ranch. Please see images, which includes extreme close-ups. [P.S., this is the 2nd of 5 specimens that I'm posting for ID today; I deeply appreciate any insight that you can provide]. With gratitude, Ryan
RetiredLawyer posted a topic in Member CollectionsFound more tracks! Been digging out and flipping these big chunks of rock since all the tracks are on the underside. I stand corrected on my loose amateur term dinosaurs - archosaurs is the correct term.

New caecilian from Triassic Colorado
DD1991 posted a topic in Fossil NewsA new amphibian-related paper is available online: Jason D. Pardo; Bryan J. Small; Adam K. Huttenlocker (2017). Stem caecilian from the Triassic of Colorado sheds light on the origins of Lissamphibia. Proceedings of the National Academy of Sciences of the United States of America. in press. doi:10.1073/pnas.1706752114. The discovery of Chinlestegophis is a groundbreaking development in recording the early evolution of extant amphibians because it not only fills a gap in the fossil record of early lissamphibians but also throws a wrench into the hypothesis of a temnospon
