About 100 million years ago, in Maryland, USA, where the Goddard Space Flight Center is now, there was a swamp. Today, there is a complex of office buildings in this place, but in 2012, amateur paleontologist Ray Stanford found a fragment of iron-coated sandstone in this area. His attention was drawn to a track left there by a herbivorous dinosaur.

The Permian is the last geological period of the Paleozoic era, following the Carboniferous and ending about 252 million years ago with the largest extinction in Earth's history. It was a time when many amphibians lived, whose body shape would more closely resemble reptiles such as lizards or crocodiles than most amphibians today.

Czytając o wulkanach rzadko myślimy o terytorium naszego kraju. A tymczasem mamy w Polsce miejsca, gdzie wulkaniczne stożki górują nad horyzontem niczym japoński Fudżi.

24 listopada mija 50 lat od jednego z najbardziej przełomowych odkryć w paleoantropologii. W 1974 r. w Etiopii, w formacji geologicznej Hadar, w rejonie miejscowości Afar, odnaleziono doskonale zachowane szczątki hominina sprzed ok. 3,2 mln lat.

Oreodonts (Merycoidodontoidea) are an extinct group of mammals. They are classified as artiodactyls, like modern pigs, cows, camels, and hippopotamuses (and even whales!). They are known only from North America, where they lived for about 35 million years, from the Eocene to the Miocene. They are among the most widely represented mammals in the fossil record of North America, and perhaps in the world.
