Dinosaur : any of a group (Dinosauria) of extinct often very large chiefly terrestrial carnivorous or herbivorous reptiles of the Mesozoic era — Merriam-Webster See also OneLook

Encyclopedia

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

Science

Paleontology, also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave body fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.5%, but more often paleontologists have to rely on relative dating by solving the “jigsaw puzzles” of biostratigraphy (arrangement of rock layers from youngest to oldest). — Wikipedia

A meter-long scorpion with massive pincers stalked ancient Britain 415 million years ago, long before forests and the better-known age of giant insects. Its surprising size and possible semi-aquatic lifestyle could reshape ideas about how early arthropods became giants.

Ancient fossils suggest insects conquered land through a long amphibious phase rather than making an abrupt jump from water to dry ground. A newly identified 324-million-year-old species still carried paddle-like abdominal limbs, revealing an evolutionary bridge between aquatic ancestors and modern six-legged insects.

Scientists have identified exceptionally rare soft tissue preserved in a 450-million-year-old crinoid fossil, more than 200 million years older than the first dinosaurs. Its delicate tube feet offer a remarkable new window into how some of Earth’s earliest reef animals lived, fed, and evolved.

Fossils collected in Osaka more than 30 years ago have revealed a surprise hiding in plain sight: four previously unrecognized bones from a giant Cretaceous mosasaur. Among them is the first confirmed premaxilla—the frontmost bone of the upper jaw—ever identified in a Japanese mosasaur fossil. Even more intriguing, parts of the skull show unusual anatomical features that don’t match known mosasaurs, raising the possibility that the remains belong to an entirely new species.

Researchers have found strong evidence that original collagen can survive inside dinosaur fossils for tens of millions of years, overturning a long-standing assumption about fossilization. The discovery could unlock hidden molecular clues about dinosaur biology, evolution, and how ancient proteins managed to survive for so long.

Two tiny ant fossils recovered in southern Saskatchewan are helping scientists better understand the evolutionary history of modern ants. Ant fossils dating from 72–56 million years ago are rare. What happened to insects such as ants during this period that saw a mass extinction wipe out all non-bird dinosaurs? How did that event reshape their world?

About 200 million years ago, furry, little egg-laying creatures evolved the ability to feed their offspring with a secretion from special glands: milk. Their evolutionary journey continued, and by about 160 million years ago, the first mammals with a real placenta had come into being. Instead of laying eggs, they gave birth to live young that had been connected directly to their mother via a placenta during pregnancy, allowing the exchange of oxygen, nutrients and waste products.

Fossilized bones can reveal a wealth of details about animals, including their size, appearance, what they ate and any injuries they may have suffered. In a paper published in the journal Royal Society Open Science, researchers in Spain describe a swollen patch on the shinbone of an Iguanodon, which they say may be evidence of an advanced skin ulcer that had reached the underlying bone. If so, this could be the first time this type of response to a bacterial infection has been reported in a […]

What did dinosaurs eat? Teeth provide important clues to understanding the ecology of dinosaurs, which became extinct approximately 66 million years ago. Their shape, structure and patterns of wear can help scientists reconstruct how these animals obtained and processed their food.
