ScienceDaily: Fossils & Ruins News

Researchers describe a new species that represents the most primitive member of lepidosaurs, Taytalura alcoberi, found in the Late Triassic deposits of Argentina. Taytalura is the first three-dimensionally preserved early lepidosaur fossil that allowed scientists to infer with great confidence it's placement in the evolutionary tree of reptiles and aids in closing the gap of our knowledge of the origin and early evolution of lepidosaurs.

Researchers suggest that the Antarctic Ice Sheet partly reached its maximum thickness before the Last Glacier Maximum.
