While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...
Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs. This list of dinosaurs is a comprehensive listing of all genera that have ever been considered to be non-avialan dinosaurs, but also includes some dinosaurs of disputed status as non-avian, as well as purely vernacular terms.
The coexistence of avian dinosaurs (birds) and humans is well established historically and in modern times. The coexistence of non-avian dinosaurs and humans exists only as a recurring motif in speculative fiction, because in the real world non-avian dinosaurs have at no point coexisted with humans. [1]
The smallest dinosaur ever found – a bird-like creature weighing less than a tenth of an ounce – has been discovered inside a drop of amber, where it was preserved for 99 million years.
2024 marks 200 years since the first dinosaur, Megalosaurus, was formally identified. Here’s what we’ve learned about the prehistoric creatures over the past two centuries.
Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found.
The Indian fossil record of dinosaurs is good, with fossils coming from the entire Mesozoic era – starting with the Triassic period (a geological period that started 251.9 million years ago and continued till 201.3 million years ago), to the Jurassic period (201 million years ago to 145 million years ago) and Cretaceous period (from 145 ...
Fossil records from North America indicate dinosaurs were still in their prime 66 million years ago, but the asteroid that struck Earth wiped them out anyway.
