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

When you only have fossils to go off of, it's hard to tell which dinosaur traits, like size and ornamentation, are related to the animals' sex, and which traits are related to other things like age. But a new kind of statistical analysis can often estimate the degree of sexual variation in a dataset of fossils.
How dinosaur research can help medicine

The intervertebral discs connect the vertebrae and give the spine its mobility. The disc consists of a cartilaginous fibrous ring and a gelatinous core as a buffer. It has always been assumed that only humans and other mammals have discs. A misconception, as a research team has now discovered: Even Tyrannosaurus rex could have suffered a slipped disc.

A unique collaboration between paleontologists, mechanical engineers and biomedical engineers revealed that the trabecular bone structure of hadrosaurs and several other dinosaurs is uniquely capable of supporting large weights, and different than that of mammals and birds.

Discovery of a new mass extinction
on September 16, 2020 at 6:00 pm
It's not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new paper, published today in Science Advances, an international team has identified a major extinction of life 233 million years ago that triggered the dinosaur takeover of the world. The crisis has been called the Carnian Pluvial Episode.

A team of researchers affiliated with several institutions in China, one in Argentina and one in Belgium has identified the fossilized remains of two previously unknown dinosaurs in China. In their paper published in the journal Peerj, the group describes the fossils, provide the name of the new dinosaur and illustrate possible clues to explain their excellent preservation.
