In this study, the well-preserved skull of a giant amphibian from the Late Triassic Stuttgart Formation (Schilfsandstein) of Bielefeld-Sieker in NW Germany is described and a new species, Cyclotosaurus buechneri sp. nov., is erected. Cyclotosaurus buechneri represents the only unequivocal evidence of Cyclotosaurus in northern Germany. The amphibian skull was found more than 40 years ago and is well known in Bielefeld and the surrounding areas but has so far never been described.

Due to the fact that knowledge of Mesozoic fish faunas of the Southern Hemisphere is still inadequate and the diversity and evolution of the Late Jurassic marine fishes of Argentina remain unclear, I study a fish recovered from the Upper Jurassic sediments of southwestern Argentina. The fish anatomy was studied comparatively with other related forms. As result, a new taxon was created. The new taxon implies a broader knowledge of the ichthyofaunas of Gondwana.

We report the first occurrence of an American lion from the late Pleistocene (≈120 000 years ago) of southeastern Hidalgo, central Mexico. The fossil material includes a lower canine tooth and a manus bone. Some areas of central Mexico were suitable hunting sites for the American lion, considering the high diversity of large mammalian herbivores that have been recorded there. The Mexican record of felids represents an important part of the Pleistocene North American diversity.
