Abstract Large theropod tracks have previously been attributed to Tyrannosaurus rex. Most identifications however, have not been supported by either clear comparison with T. rex osteology or the stratigraphic position of the track. There is a conspicuous absence of tracks in the Upper Cretaceous (Maastrichtian) Hell Creek, Lance, Scollard, Frenchman, and Denver Formations (Lancian, North American Land Mammal Age), where T. rex body fossils have been found. A large tridactyl track is described…

The tracks of giant theropods (Jurabrontes curtedulensis ichnogen. & ichnosp. nov.) from the Late Jurassic of NW Switzerland: palaeoecological & palaeogeographical implications
Abstract Jurabrontes curtedulensis, a new ichnogenus and species of Late Jurassic giant theropod dinosaur track is described based on very well-preserved and morphologically-distinct tracks, all
Dinosaur trackways from the Upper Cretaceous Oldman and Dinosaur Park formations (Belly River Group) of southern Alberta, Canada, reveal novel ichnofossil preservation style
Dinosaur tracksites recently discovered in exposures of the Belly River Group in the Milk River Natural Area (MRNA) and Dinosaur Provincial Park (DPP) of southern Alberta represent a novel type of
The largest European theropod dinosaurs: remains of a gigantic megalosaurid and giant theropod tracks from the Kimmeridgian of Asturias, Spain
The recently proposed distinction between robust and gracile large to giant theropod tracks and their possible trackmakers during the Late Jurassic-Berriasian is discussed, and megalosaurids seem to be more abundant than previously recognized and occur in basically all Jurassic deposits where theropid remains have been found.
Exploring Possible Ontogenetic Trajectories in Tyrannosaurids Using Tracks from the Wapiti Formation (Upper Campanian) of Alberta, Canada
ABSTRACT Fossil tracks should theoretically capture differences in pedal anatomy between growth stages of the same taxon, particularly those related to the soft tissue of the foot, providing a more
New discoveries of Isochirotherium herculis (Egerton 1838) and a reassessment of chirotheriid footprints from the Triassic of the Isle of Arran, Scotland
Synopsis Several in situ trackways and individual chirotheriid footprints have been found at a number of locations along the southern coast of the Isle of Arran. A locality on the coast near Sliddery
Tracking Tyrannosaurus: Notes on Purported T. rex Tracks
Purported T. rex tracks (genus Tyrannosaurus) are rare and, if poorly preserved, difficult to identify or to distinguish with certainty from the tracks of hadrosaurs found in the same deposits. Six
Dinosaur tracks at Cañadón de las Campanas and Villa El Chocón area (Late Cretaceous, Candeleros Formation), Patagonia, Argentina

A Diverse Dinosaur-Bird Footprint Assemblage from the Lance Formation, Upper Cretaceous, Eastern Wyoming: Implications for Ichnotaxonomy
A diverse assemblage of dinosaur and bird tracks from Niobrara County, Wyoming, represents the first vertebrate ichnofauna reported from the bone-rich Lance Formation (Maastrichtian, Upper
Osteology of Tyrannosaurus Rex: Insights from a nearly complete Skeleton and High-Resolution Computed Tomographic Analysis of the Skull
High-resolution x-ray computed tomographic analysis of the skull reveals internal details not previously observed, raising several possibilities, including the complete absence of a bony sternum in tyrannosaurids.

Abstract Tracks can potentially offer unique sources of information, providing insight into the environments, gait and posture, locomotion and behaviour. Track preservation can yield important
A track of the giant theropod dinosaur Tyrannosaurus from close to the Cretaceous/Tertiary Boundary, northern New Mexico
The first unequivocal example of a large tyrannosaur track attributable to the species Tyrannosaurus rex is an 86 cm long tetradactyl pedal impression assigned to Tyrannosauripus pillmorei ichnogen.
