“#Fossil growth reveals insights into the climate” Morphology of a humerus of Panthasaurus maleriensis from the Late Triassic of Central India. Credit: Elzbieta M. Teschner Panthasaurus maleriensis lived about 225 million years ago in what is now India. It is an ancestor of today’s amphibians and has been considered the most puzzling representative of the…
“#The oldest Neanderthal DNA of Central-Eastern Europe” Aerial view of Stajnia Cave. Credit: Marcin Zarski Around 100,000 years ago, the climate changed abruptly and the environment of Central-Eastern Europe shifted from forested to open steppe/taiga habitat, promoting the dispersal of wooly mammoth, wooly rhino and other cold adapted species from the Arctic.
