Morphology of Palaeospondylus shows affinity to tetrapod ancestors
Misha posted a topic in Fossil News
Hirasawa, T., Hu, Y., Uesugi, K. et al. Morphology of Palaeospondylus shows affinity to tetrapod ancestors. Nature (2022). https://doi.org/10.1038/s41586-022-04781-3 Researchers used synchrotron radiation X-ray micro-computed tomography, to highlight the similarities in morphology between Palaeospondylus gunni and sarcopterygian fishes, specifically stem tetrapods. I haven't read the full paper yet but any news on this enigmatic organism is always fascinating and exciting. What do you all think about this?- 4 replies

Greetings, I’ve recently gotten back into prospecting fossils and I’m looking for some suggestions on sites to visit in western Pennsylvania. I frequently visit Ambridge PA to find fern and Calamite fossils from the Mahoning fm and would like to find more. I also would like to find fossils of early Permian (tetrapods, plants, or invertebrates). I hear that Washington county (south of Pittsburgh) has some great spots and would like to know if it were true. I also would like to show some of my findings from Ambridge as well. Note: I’d like this to be suggested places not j

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com- 5 replies

Red Hill is a site I first went to 10 years ago with my son, Ian who was 10 at the time. It is a very deep road cut into the uppermost part of the Catskill Formation representing a late Fammenian river system that was draining the Acadian mountains to the east and emptying into the inland sea in western PA and OH. It is one of a handful of sites in the world where Devonian tetrapods have been found. The site has fossil layers in both channel margin (red layers) and flood plain (gray-green layers) facies. While it is an active research site and groups go there under the understanding that anyth

New update from the Cretaceous of Romania :)
The Amateur Paleontologist posted a topic in General Fossil Discussion
Hey everyone - hope you're all well Wanted to share this (in part cause I'm half Romanian ).. It's a conference poster presenting some recent research findings regarding a productive vertebrate microsite from the Maastrichtian (Late Cretaceous) of Hatzeg Basin (Romania). It reports some new micro-vertebrate material, including crocodile teeth, lil' bones and even eggshell. Voicu, Vasile & Csiki-Sava (2018). The Cretaceous Swamp just gets bigger: new data on the faunal composition of the Pui Swamp microvertebrate bonebed, Maastrichtian of the Haţeg Basin. The Tenth Intern- 3 replies
