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

By cutting into dinosaur bones and analyzing the growth lines, a team of researchers discovered that T. rex and its closest relatives got big thanks to a huge growth spurt in adolescence, while its more distant cousins kept on growing a little bit every year throughout their lives.
- Only dinosaurs found in ireland described for the...on November 24, 2020 at 4:13 pm
The only dinosaur bones ever found on the island of Ireland have been formally confirmed for the first time by a team of experts. The two fossils are from two different dinosaurs, a four-legged plant-eater called Scelidosaurus and a two-legged meat-eater similar to Sarcosaurus.

New research suggests that dinosaurs were not in decline before the asteroid hit. The study contradicts previous theories and concludes that had the impact not occurred dinosaurs might have continued to be the dominant group of land animals.
- Baby dinosaurs were 'little adults'on November 6, 2020 at 5:33 pm
Paleontologists have described for the first time an almost complete skeleton of a juvenile Plateosaurus and discovered that it looked very similar to its parents even at a young age. That could have important implications for how the young animals lived and moved around. The young Plateosaurus, nicknamed 'Fabian', was discovered in 2015 at the Frick fossil site in Switzerland.
- The first duckbill dinosaur fossil from Africa...on November 5, 2020 at 1:37 pm
The first fossils of a duckbilled dinosaur have been discovered in Africa, suggesting dinosaurs crossed hundreds of kilometres of open water to get there.

- Bird with tall, sickle-shaped beak reveals hidden...on November 25, 2020 at 4:00 pm
A Cretaceous-age, crow-sized bird from Madagascar would have sliced its way through the air wielding a large, blade-like beak and offers important new insights on the evolution of face and beak shape in the Mesozoic forerunners of modern birds. An international team of researchers led by Ohio University professor Dr. Patrick O'Connor and Stony Brook University professor Dr. Alan H. Turner announced the discovery today in the journal Nature.
- Fossils show 66 million years of insects eating...on November 25, 2020 at 12:29 pm
Exquisitely preserved feeding marks on fossil conifer leaves show that the same insect feeding and fungi persisted for millions of years on the same type of plant, from ancient Patagonian rainforests to the modern rainforests of the tropical West Pacific.
- T. rex had huge growth spurts, but other dinos...on November 25, 2020 at 12:00 am
Tyrannosaurus rex was one of the biggest meat-eating dinosaurs of all time—it measured up to 42 feet long from snout to tail and would have weighed in at around 16,000 pounds. And it wasn't alone—some of its less-well-known cousins could reach nearly the same size. Scientists have previously shown that T. rex got so big by going through a huge teenage growth spurt, but they didn't know if that was true for just tyrannosaurs, just them and their close relatives, or perhaps all big bipedal […]

Dialling down the Sun's heat a notch by injecting billions of shiny sulphur dioxide particles into the stratosphere could curtail devastating drought across parts of Africa, new peer-reviewed research has reported.
- Ireland's only dinosaurs discovered in Antrimon November 24, 2020 at 12:26 pm
The only dinosaur bones ever found on the island of Ireland have been formally confirmed for the first time by a team of experts from the University of Portsmouth and Queen's University Belfast, led by Dr. Mike Simms, a curator and paleontologist at National Museums NI.
