Dinosaur : any of a group (Dinosauria) of extinct often very large chiefly terrestrial carnivorous or herbivorous reptiles of the Mesozoic era — Webster
Dinosaurare a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago; their dominance continued through the Jurassic and Cretaceous periods. Reverse genetic engineering and the fossil record both demonstrate that birds are modern feathered dinosaurs, having evolved from earlier theropods during the late Jurassic Period. As such, birds were the only dinosaur lineage to survive the Cretaceous–Paleogene extinction event 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds. — Wikipedia

Before they evolved the ability to fly, two-legged dinosaurs may have begun to flap their wings as a passive effect of running along the ground. […]
Duck-billed dinosaurs: Evolutionary bursts led to...
on May 2, 2019 at 2:48 pm
The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 ton giants so successful? A new study shows that their special adaptations in teeth and jaws and in their head crests were crucial, and provides new insights into how these innovations evolved. […]
Flowering plants, new teeth and no dinosaurs: New...
on May 1, 2019 at 3:46 pm
A new study has identified three factors critical in the rise of mammal communities since they first emerged during the Age of Dinosaurs: the rise of flowering plants; the evolution of tribosphenic molars in mammals; and the extinction of non-avian dinosaurs, which reduced competition between mammals and other vertebrates in terrestrial ecosystems.

A team of researchers affiliated with institutions in Argentina and the U.K. has found evidence of a dinosaur that walked on all fours when it was young and then switched to walking on two legs as it grew to adulthood. In their paper published in the journal Scientific Reports, the group describes their study of Mussaurus patagonicus, an early sauropod species that lived in what is now Argentina, and what they learned about it.

Researchers have for the first time detected chemical traces of red pigment in an ancient fossil—an exceptionally well-preserved mouse, not unlike today's field mice, that roamed the fields of what is now the German village of Willershausen around 3 million years ago. […]
