Of course, dinosaurs didn’t just appear out of thin air. Dinosaurs lived throughout the Mesozoic Era, which began 245 million years ago and lasted for 180 million years. 'It is probable that they were either carnivores or omnivores, but they definitely were not herbivores,' says Paul.

However, the age of the dinosaurs came to an end around 66 million years ago with the Cretaceous–Paleogene extinction event. "Sue" is 12 metres long from head to tail, and estimated to have weighed around seven tonnes, underlining the rapid growth rate of such dinosaurs during their (relatively) short lives. By taking thin slices of bones, these rings can be viewed under a polarised light source. By the same token, other dinosaurs seem to have grown more like crocodiles and less like mammals, at a slow and steady pace, without the accelerated curve seen during infancy and adolescence. Explore the age of the dinosaurs, from the time they first appeared to the mass extinction 66 million years ago. What was life like during the Triassic Period? Dinosaurs are one of the most successful groups of animals to have roamed the planet. You may have heard about periods of time such as the Triassic, Jurassic and Cretaceous periods, but do you know what these names actually mean? Dinosaurs lived for around 177 million years. During the Jurassic period, dinosaurs branched off into several types, including huge sauropods such as Diplodocus, and fearsome predators such as Allosaurus. It isn't easy to tell from dinosaurs' fossilised remains how long they lived. It isn't easy to tell from dinosaurs' fossilised remains how long they lived. The growth lines also offer a guide to a dinosaur's growth rate at different stages of its life. Crucially, however, it reveals that there were also a number of different early dinosaur species in the mix. Get email updates about our news, science, exhibitions, events, products, services and fundraising activities. According to Dr John Nudds, a palaeontologist at the University of Manchester: "If you compare dinosaurs to present-day animals, we might expect that the very large herbivores - things like brachiosaurs and Diplodocus, which were comparable in size to an elephant - would have lived, therefore, for 70-80 years; maybe a bit more. That’s much longer than they’ve been extinct. If you think of something like an eagle or raven, they live for 20-30 years, and that would probably have been the lifespan of a T. What fills this gap is still not known, but may include the 240-million-year-old partial fossil of an animal called Nyasasaurus parringtoni, discovered in Tanzania near Lake Nyasa in the 1930s. This means that they had to modify the hip and backbone connections, the tops of the thigh bones where the bones join the hip, plus the joints in the knees and ankles. The era is divided into three periods. We hope that you enjoyed this page. Many fields of study contribute to our understanding of dinosaurs, including physics (especially biomechanics), chemistry, biology, and the Earth sciences (of which paleontology is a sub-discipline). If sauropods followed this pattern, that would point to a cold-blooded metabolism, and their estimated life spans would once again edge up toward the multiple-century mark. Next time you’re asked ‘How long ago did dinosaurs live?’ here’s your reply: Dinosaurs lived from somewhere between 243 and 231 million years ago right up to the Cretaceous–Paleogene extinction event, which occurred around 66 million years ago.

One shouldn't rush to conclude that just because some of the relatives and descendants of dinosaurs regularly hit the century mark, dinosaurs must have had long life spans as well.

Swans and turkey buzzards can live for over 100 years, and small parrots often outlive their human owners. Explore more than 300 dinosaurs by name, shape or when and where they lived. Their possible maximum age can be estimated from the maximum lifespans of modern reptiles, such as the 66-year lifespan of the common alligator ( Alligator mississippiensis ) and the impressive lifespan of a Black Seychelles Tortoise ( Geochelone (Aldabrachelys) sumeirei ). The early birds, such as Archaeopteryx, also began to appear. "Traditional" estimates based on slow, reptilian growth rates, combined with the enormous size of dinosaurs, led scientists to conclude it could be up to several hundred years. They’re all geological periods, and part of the geological timescale. This caused around 75% of all species to become extinct, including all of the dinosaurs that hadn’t evolved into birds. Geological periods all relate to specific layers of rock. Privacy notice. All Rights Reserved. Available for everyone, funded by readers. So what can we conclude? However, dinosaurs still exist – in the shape of birds – so strictly speaking they’re still alive! It isn't easy to tell from dinosaurs' fossilised remains how long they lived. The Eoraptor, shown above, was one of the earliest dinosaurs. Active Wild Pinterest Active Wild Facebook. Before anything else, of course, it helps to determine the cause of death of any given dinosaur. Probably starting off with a body length of only a couple of metres, they would have been bipedal with small, grasping hands. … Also, with some important exceptions (such as parrots), smaller animals tend to have shorter lifespans, so the average 25-pound Velociraptor might have been lucky to live beyond a decade or so. The ability to walk upright on straight legs was the key to the dinosaurs’ success. 'But when they first appeared, they were already recognisably dinosaurs. Dinosaur bones grew like those of other vertebrates, by adding new bone matter to the outside of the bone. 'There are a number of different features that define a dinosaur, but perhaps the clearest things are to do with modifications to their hips and to their legs,' explains Paul. Knowledge about dinosaurs is derived from a variety of fossil and non-fossil records, including fossilized bones, feces, trackways, gastroliths, feathers, impressions of skin, internal organs and soft tissues. Clearly, until we establish more details about the metabolism and growth rates of various species, any serious estimates of dinosaur lifespans have to be taken with a gigantic grain of prehistoric salt!
