Scientists say they have found a new dinosaur species which could have grown to 65ft tall – three times the height of a T-Rex . Nicknamed the Sibirosaurus , the creature would have been among the largest to roam the Earth 100 million years ago . It is thought to be related to the Titanosaurus which grew to 131ft long and weighed 90 tons - the equivalent of nine African elephants . Scientists say they have found a new dinosaur species , nicknamed the Sibirosaurus , which could have grown to 65ft tall . Pictured : a Brachiosaurus . The news comes after experts in Russia discovered fossils in rocks on the banks of the Kiya River in Western Siberia in 2008 . Pictured : fragments taken for examination . The news comes after experts in Russia discovered fossils in rocks on the banks of the Kiya River in Western Siberia in 2008 . The rocks could not be removed so scientists from Tomsk State University extracted fragments from the sandstone for examination , The Siberian Times reported . Dr Stepan Ivantsov , a scientific researcher in the Laboratory of Mesozoic and Cenozoic Continental Ecosystems , said they originally believed the remains were of a very large herbivore . It took many years of research to discover it was an entirely new dinosaur . It is thought a dinosaur foot found at the same location in 1995 may also belong to the newly identified species . He told the newspaper : 'When we discovered this finding , it was only clear that the remains belonged to a very large herbivorous dinosaur from the sauropods group . It was the first scientifically described dinosaur from this group in Russia . 'Now after work on the extraction of all the remnants and the restoration ( of the bones ) are almost completed , we can confidently say that we have found a new species , and maybe even genus . Dr Stepan Ivantsov ( pictured left ) said they originally believed the remains were of a very large herbivore . The rocks could not be removed so scientists from Tomsk State University extracted fragments from the sandstone for examination . 'If we talk about our discovery , this dinosaur lived in the Late Cretaceous period , that is about 100 million years ago . ' Experts believe a dinosaur foot found at the same location in 1995 may also belong to the newly discovered species . Dr Ivantsov said : 'We constantly find the remains of dinosaurs on this site , near Shestakovo village . They fall down from the steep river bank regularly and we collect them . ' Bones including part of a shoulder blade will be exhibited permanently in Paleontological Museum of Tomsk State University . They were named after the mythical Titans of Ancient Greece - giant deities of incredible strength . Titanosaurs have very long necks and whip-like tails , tiny heads and thick stumpy legs . They ate plants and were armoured with small bony plates along its back which helped protect them from predators . Titanosaurs were some of the biggest dinosaurs to ever walk the earth and weighed up to 90 tons . Pictured : fossil fragments . David Norman , director of studies in Earth Sciences at Cambridge University , said it is not rare to find dinosaur remains , but the discovery is notable because it suggests the large herbivores lived in areas they have not been found in before . He said : 'It is a case of look and usually you will find . Although , they are animals that lived on land and because of that the chances of them being preserved is less than if they were creatures in the seas or rivers , so they are certainly rarer . 'On that basis the discovery that has been made is interesting because it is from a part of the world that has n't yielded these particular sorts of dinosaurs . 'It therefore increases the geographic range - they have been found in Africa , Europe and China before . It is interesting . ' Dr Norman said Titanosaurs are large ling-necked dinosaurs which travelled in herds . He said : 'It is an animal a bit like Dippy , the dinosaur in the hall of the Natural History Museum - it is that sort of shape . It is long-necked and has a long tail with an elephant sized body . ' He said dinosaur footprints suggest they travelled in herds with the largest members on the outside creating a kind of ring of steel which protected the women and children in the centre .
Dinosaur appears to be similar to Titanosaurus which grew to 131 ft long . Nicknamed the dinosaur , the dinosaur would have been among the largest to roam the earth 100 million years ago . News comes after experts in Russia discovered fossils in dinosaurs in 2008 .
