New PaleoLab paper.
Yesterday, PeerJ published a new paper authored by old (Marco Aurélio de França) and current (Júlio Marsola, Annie Hsiou, Max Langer) PaleoLab members, describing new jaw elements of the cretaceous titanosaurid sauropod Maxakalisaurus topai, found in the area of Prata, Minas Gerais, Brazil.
This week the PaleoLab was visited by the palaeontologists Mike Caldwell (University of Alberta, Canada) and Randall Nydam (Midwestern University, USA), who worked on a join project with Annie Hsiou. In the photo, one of the many happy-hours of these days, with the visitors on the back.
New PaleoLab paper.

Ornitosuchians complain!
Field work in Argentina.
Between May 2nd-13th, the PaleoLab team, along with colleagues from MACN, CRILaR and UFSM, conducted a field-trip to the triassik deposits of the Ischigualasto Formation, at the Hoyada del Cerro Las Lajas site, in La Rioja, Argentina.

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.
This weekend Paläontologische Zeitschrift published the formal naming of the "Mariante Rhynchosaur" (see here).
