This fossil footprint from northern New Mexico is 96 cm long and given its Late Cretaceous age (about 66 million years old), it very likely belonged to the giant theropod dinosaur Tyrannosaurus rex. In 2016 the size of this individual was estimated at 11.4 meters (37.4 ft) and 5.8-6.9 tonnes (6.4-7.6 short tons). [2]
Tyrannosaurus (/ t ɪ ˌ r æ n ə ˈ s ɔː r ə s, t aɪ-/) [a] is a genus of large theropod dinosaur.The type species Tyrannosaurus rex (rex meaning 'king' in Latin), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
Previously discovered T. rex skeletons were usually missing over half of their bones. [10] It was later determined that Sue was a record 90 percent complete by bulk, [11] and 73 percent complete counting the elements. [12] Of the 360 known T. rex bones, around 250 have been recovered. [1]
Lockley and Hunt reported a possible T. rex footprint in 1994. Pérez-Moreno and others performed another phylogenetic analysis of the Tyrannosauridae and found additional support for reclassifying the family as coelurosaurs. [10] They found tyrannosaurids to lie outside of the Maniraptoriformes.
Although Larson (2013) saw Jane as more identical to CMNH 7541 and LACM 28471 than to adult T. rex in having a higher tooth count, large pneumatic foramen on the center of the quadratojugal, T-shaped postorbital, and fused shoulder blade and pelvis, [72] Yun (2015) concurred with the opinion of most workers that Nanotyrannus is a juvenile T ...
Scientists have found the U.K.’s largest dinosaur footprint site ever. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...

A second footprint that may have been made by a specimen of Tyrannosaurus was first reported in 2007 by British paleontologist Phil Manning, from the Hell Creek Formation of Montana. [76] This second track measures 72 centimeters (28 in) long, shorter than the track described by Lockley and Hunt.
