Enigmacursor mollyborthwickae: New species of dog-sized dinosaur discovered
Experts have discovered a new small species of has been named Enigmacursor mollyborthwickae, and scientists say it lived around 150 million years ago, during the late Jurassic roamed around what is now North America, running around the feet of famous giants like the will now become the first new dinosaur to go on display at London's Natural History Museum in more than ten years. What did experts discover about the new dinosaur? The small dinosaur was found in America's Morrison Formation, in the western United States - which has previously produced some of the world's most famous dinosaurs, including the Stegosaurus and it was first discovered, it was wrongly categorised as a Nanosaurus but scientists have now worked out it is a different new name, Enigmacursor, means 'puzzling runner' - and palaeontologists think it was the size of a labrador to experts, it stood 64 cm tall and 180 cm long but with much bigger feet and a tail that was "probably longer than the rest of the dinosaur." The fossilised remains are the most complete of any in the world for early small big dinosaur bones have been the biggest prize, so there has been less interest in digging out smaller hope that this new discovery could help them understand the diversity of dinosaurs in the Late Jurassic period. Professor Susannah Maidment, from the Natural History Museum, said the new species could be the first of many small dinosaurs to be found in western USA."While the Morrison Formation has been well-known for a long time, most of the focus has been on searching for the biggest and most impressive dinosaurs."She added: "Smaller dinosaurs are often left behind, meaning there are probably many still in the ground."Enigmacursor shows that there's still plenty to discover in even this well-studied region."The new dino will now go on permanent display at London's Natural History Museum.

Never-before-seen dog-sized dinosaur that dodged 32ft flesh-eating giants and killer crocs found after 150 MILLION years
A "NEVER-BEFORE-SEEN" dinosaur that dates back 150 million years has been revealed – and is now on show in the heart of London. The speedy creature would've dodged 32ft flesh-eating giants and even crocodiles to survive in prehistoric USA, scientists told The Sun. 13 Officially named Enigmacursor mollyborthwickae, the two-legged sprinter is available for free public viewing at the Natural History Museum from Thursday, June 26. The metre-long creature's fossilised skeleton is remarkably well-preserved, stretching over a metre long (3.2ft) – and about 50cm (1.6ft) tall. Visitors will be able to get up close to the early American creature, which lived alongside iconic dinos like Diplodocus and Stegosaurus. "What we're dealing with here is a new species of dinosaur that comes from Colorado in the western USA," said Professor Paul Barrow, of the Natural History Museum, speaking to The Sun at the grand unveiling. "It was discovered back in 2021 and we were able to acquire it thanks to an amazingly generous private donation, which allowed us to buy it for the museum." BACK IN TIME The dinosaur itself is believed to have not been fully grown. Normally the upper and lower parts of the creature's back bones would fuse together as the animal aged. But they weren't fully fused together, suggesting that the dino may have been quite young. And it certainly would've been surrounded by dino pals. "At the time, Colorado would have been a floodplain," said Professor Susannah Maidment, of the Natural History Museum, speaking to The Sun. Walking With Dinosaurs: Official Trailer, BBC "It would have had a series or rivers coming down from high land to the west, and there would have been dinosaurs all over it. "Some of the most famous dinosaurs – thinks like Diplodocus and Camarasaurus and Brachiosaurus. "And so this little dinosaur would have been running around at the feet of those giants." GREEN MACHINE This particular dinosaur was a herbivore, meaning it mostly ate plants. 13 But because flowering plants hadn't evolved yet, Professor Maidment told us, it "would have just been eating things like cycads and ferns". The dinosaur didn't need to move fast to eat – but it did need speedy legs to avoid being eaten. It lived alongside deadly predators, including prehistoric crocodiles. "We know it's a very speedy little dinosaur," said Professor Paul Barrow. 13 13 "It has very long hind legs – it walks on its hind legs only. "So its main defence against predators would actually have just been a speedy getaway. "And it's living at the same time as quite a lot of other large predatory dinosaurs. "Probably the most famous of which is a thing called Allosaurus, which is a big carnivore that gets up to about nine or 10 metres (29 to 32ft) in length – it's quite common at the time.

DIG IT The creature was first unearthed in 2021 from a commercial quarry. And it was thought to be a Nanosaurus, a "poorly-known" species that was first named in 1870s. The Enigmacursor was acquired from the David Aaron Ltd gallery with support from David and Molly Lowell Borthwick (after whom the dinosaur is now named). 13 13 And Natural History Museum scientists renamed it after analysing the specimen, confirming it as a species new to science. But there is still a mystery: exactly how fast the nippy little creature could run. "It was a two-legged dinosaur and so it had very small forelimbs actually," Professor Maidment told us. "But we don't really know how fast it would have run at all. "It probably might have been able to just about outrun us – but probably not much faster than that." 13 13
