Dinosaurs Suffered From Cancer, TooĪ Centrosaurus skeleton in the mass dearth assemblage at the Royal Tyrrell Museumĭinosaurs are often celebrated for being big, fierce and tough. The fact that the tail goes with the other fossils found at the site also confirm that they all go to one individual, underscoring the fact that Spinosaurus had strange body proportions unlike any other dinosaur yet discovered. The tail is more like a paddle than what’s seen in other carnivorous dinosaurs and would have been suited to swishy, side-to-side motions that propelled Spinosaurus through the water. The appendage, found at the same quarry as the 2015 skeleton, is long and deep. Fossils reported in 2015 went a step further-flat feet and dense bones indicated that Spinosaurus spent a great deal of time in the water and is the first known semi-aquatic dinosaur. Paleontologists have long suspected that the giant carnivore Spinosaurus spent much of its time around the water. Winner By a Tail Spinosaurus used its tail to swim This hints that some key dinosaur traits, such as warm-bloodedness and insulating body coverings, evolved early in their history and were elaborated upon as dinosaurs eventually diversified into all sorts of shapes and sizes. This small, insect-eating reptile likely moved nimbly to catch lunch and may have sported a coat of fuzz to help regulate its body temperature.

While not a dinosaur itself, this animal was close to the ancestors of both dinosaurs and related flying reptiles called pterosaurs. This year experts reported the discovery of a tiny reptile from the Triassic of Madagascar they named Kongonaphon. Some of the key traits that allowed dinosaurs to be such an evolutionary success story-from fuzzy feathers to warm-running metabolisms-may have first evolved in their tiny ancestors. Life restoration of Kongonaphon kely, a newly described reptile near the ancestry of dinosaurs and pterosaurs Tiny Fuzzball Shows How Dinosaurs Started Small As we anticipate what the fossil record might reveal in 2021, here’s a look back at ten dinosaur discoveries that surprised and enthralled dinosaur enthusiasts this year. The discoveries continue even now, with the fluffy “maned” dinosaur Ubirajara named just last weekend. Even in a year where fossil explorations have been curtailed because of the COVID-19 pandemic, paleontologists have dug deep to describe dozens of new species and unlock new secrets about our favorite prehistoric creatures. There’s never been a better time to be a dinosaur fan.
