New "amphibian" from the Brazilian Permian


This week Journal of Systematic Palaeontology published the description and naming of a new temnospondyl species, Konzhukovia sangabrielensis (see here), from the Rio do Rasto Formation, Permian of Rio Grande do Sul. Estevan Eltink figures as a co-author of the paper, which is a collaboration with CAPPA/UFSM palaeontologists.

Welcome Brasinorhynchus!


This weekend Paläontologische Zeitschrift published the formal naming of the "Mariante Rhynchosaur" (see here). More than 25 years after its discovery, three generations of "rhynchosaurologists" were needed to deliver the description of one of the more emblematic fossils of the Triassic of Rio Grande do Sul. Authors include César Schultz (supervisor of Max's MSc thesis at UFRGS), Max himself, and his ex-student Felipe Montefeltro (now at UNESP).

A bit late because of the renewing of the site. During February, the PaleoLab team has been on the field in Venezuela. A lot of work, some fossils, and a responsible amount of beer. Photograph in Sierra Nevada National Park (from left to right: Sílvio, Marcos, Monica, Simone, Max, Gabriel, Damian, and Ascanio).
