Sources on the relation between modern Lissamphibia and stem tetrapods
Mahnmut posted a topic in Questions & Answers
Hello together, I am looking for papers about the relation between modern amphibians and stem tetrapods (this time not for model building purposes but for an academic paper I write on amphibians as model organisms ( I have the medical topics covered but wanted to include a bit of palaeontology). Also, is there any hint in the fossil record on limb regeneration like some modern amphibia can do? Thanks, J- 5 replies

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 International Zoological Congress of “Grigore Antipa” Museum, 21-24 November 2018, Bucharest, Romania Here's a link to the poster from where you can download a pdf of it : Voicu et al. 2018 Hatzeg poster -Christian- 3 replies

Specimen was found using a sifting method at or around 1 feet of water in the banks of the Caloosahatchee River. Among other finds in same 2sq meters where angulosplenials, there is no way to take those into the Species level but are without doubt representations of the Ranidae Family. Also found was portion of a fossilized pelvis of what appear to be Deer (this is not corroborated to the Species), numerous scales of the fish family Lepisosteidae (Garfish), other unidentified but likely amphibian bones, 2 shark teeth (yet to be identified), unidentifiable bone fragments no larger than 2 inches, Drum fish teeth, unidentifiable teeth fragments, yet to be identified Cat Fish dorsal spikes and an innumerable variety of mollusk fossils. The presence of both amphibians and sharks in this locality demonstrate that within the Late Pliocene and Early Pleistocene Epochs this area of Glades County, FL was at one point lacustrine and at another a shallow sea environment. One can only speculate that there was intense glacial activity within such time frame.
