Nyasasaurus

Paleontologists think that they may have identified the earliest known dinosaur, which was no bigger than a Labrador retriever and lived 243 million years ago, during the Triassic Period. This is 10 million years earlier than the previously oldest known dinosaurs, and could change researchers’ views of how they evolved.

Pachycephalosaurids had domed heads with thick, bony protuberances, which paleontologists hypothesized the dinosaurs used in courtship behavior, perhaps to determine which male would be allowed to mate. A new study indicates that these dinosaurs might have been bashing themselves in a number of different ways.

Molecular Analysis of Dinosaur Osteocytes Indicates Presence of Endogenous Molecules

20 years ago, Mary Schweitzer discovered that she spotted the effects of what could only be described as a red blood cell in a slice of dinosaur bone. This seemed impossible, since organic remains weren’t supposed to be able to survive the fossilization process. Numerous tests indicated that the spherical structures were blood cells from a 67-million year old Tyrannosaurus rex.

Bushy-Tailed Fossilized Theropod Could Mean that Most Dinosaurs Had Feathers

S-albersdoerferi-feathers

A particularly well-preserved bushy-tailed fossilized theropod could imply that most of dinosaurs actually had feathers. The dinosaur, named Sciurumimus albersdoerferi lived 150 million years ago, during the Jurassic period of the Mesozoic era, in what is now Germany.
