Previously, the oldest record of dinosaurs was from Brazil and Argentina and dated back to the mid-late Carnian stage, about 233.23 to 231.4 million years ago. Nyasasaurus comes from a deposit conventionally considered Anisian in age, meaning that it would predate other early dinosaurs by about 12 million years. [ 1 ]
A crocodile-like creature bit the neck of a flying dinosaur some 76 million years ago – and scientists have proof. Archaeologists found the fossilized neck bone of the young pterosaur in Canada ...
Only two non-avian dinosaur fossils have been found in Oregon, and both are isolated bones in marine rocks, which evidently bloated and floated out to sea. One is the pedal phalanx of a large (5 m long) ornithopod , intermediate in size and morphology between Tenontosaurus and Eolambia , from the Early Cretaceous ( Albian ) Hudspeth Shale near ...
A rare dinosaur bone bed containing 115-million-year-old fossils has been unearthed in Maryland, officials and experts say. During a dig at Prince George’s County’s Dinosaur Park in Laurel in ...
The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...
A near complete skull fossil found in Antarctica has revealed the oldest known modern bird — a mallard duck-size creature related to the waterfowl that live by lakes and oceans today, a new ...
The earliest direct evidence of life are stromatolites found in 3.48 billion-year-old chert in the Dresser formation of the Pilbara Craton in Western Australia. [4] Several features in these fossils are difficult to explain with abiotic processes, for example, the thickening of laminae over flexure crests that is expected from more sunlight. [57]
