The remains have been lost, but the sacrum drawing remains. It suggests a sacrum of almost 1.3 m (4.3 ft) long, [432] making it the largest dinosaur sacrum discovered so far, except those of Argentinosaurus and Apatosaurus. [433] In 2010, the femur of a large sauropod was discovered in France. The femur suggests an animal that grew to immense ...
One of the features of theropod dinosaurs that has attracted most scientific interest is the fact that the group includes the largest terrestrial predators of the Mesozoic Era. This interest began with the discovery of one of the first known dinosaurs, Megalosaurus, named in 1824 for its large size.
Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur Argentinosaurus huinculensis, which is the largest dinosaur known from uncontroversial and relatively substantial evidence, estimated to have been 70–80 t (77–88 short tons) and 36 m (118 ft) long.
The remains of one of Europe’s largest ever land-based predator dinosaurs have been discovered in the United Kingdom, scientists said Thursday.
Yutyrannus was a large bipedal predator. The holotype and oldest-known specimen has an estimated length of 9 metres (29.5 ft) and an estimated weight of about 1,414 kilograms (3,117 lb). [ 1 ] In 2016, Gregory S. Paul gave lower estimations of 7.5 metres (24.6 ft) and 1.1 tonnes (1.2 short tons). [ 4 ]
Utahraptor (meaning "Utah's predator") is a genus of large dromaeosaurid (a group of feathered carnivorous theropods) dinosaur that lived during the Early Cretaceous period from around 135 to 130 million years ago in what is now the United States.
The UK's biggest ever dinosaur trackway site has been discovered in a quarry in Oxfordshire. About 200 huge footprints, which were made 166 million years ago, criss-cross the limestone floor.
