New perspectives on morphological variation in tridactyl footprints: clues to widespread convergence in developmental dynamics
Developmental studies of the vertebrate foot support the view that morphological similarity owes as much to intrinsic (formal) developmental dynamics as to extrinsic (functional) influences, and the morphologies of ornithopod, non-avian theropod and most bird feet are convergent despite significant differences in size and functional adaptation.
North America's largest dinosaur trackway site: Implications for Morrison Formation paleoecology
Little-known exposures of the Upper Jurassic Morrison Formation from the Purgatoire Valley of southeastern Colorado have yielded the world's largest continuously mapped assemblage of dinosaur
The track record of Mesozoic birds: evidence and implications
The occurrence, systematics, palaeobiological and evolutionary significance of Mesozoic bird and birdlike tracks are reviewed in the light of recent new discoveries in East Asia, Africa and North
The fossil trackway Pteraichnus is pterosaurian, not crocodilian: Implications for the global distribution of pterosaur tracks
There has been much confusion regarding the fossil footprint record of pterosaurs, with both non‐pterosaurian tracks assigned to pterosaurs, and pterosaurian tracks assigned to non‐pterosaurian
New pterosaur tracks (Pteraichnidae) from the Late Cretaceous Uhangri Formation, southwestern Korea
Numerous footprints of dinosaurs, pterosaurs and birds, together with arthropod tracks, have been discovered in the upper Cretaceous Uhangri Formation which crops out along the south-western
Titanosaurid trackways from the Upper Cretaceous of Bolivia: evidence for large manus, wide-gauge locomotion and gregarious behaviour
Abstract A preliminary study of the Humaca dinosaur tracksite, in the Departamiento Chuquisaca (Bolivia), has revealed 11 parallel trackways of subadult sauropods travelling to the WNW as a group.
Flamingo and duck-like bird tracks from the Late Cretaceous and Early Tertiary: evidence and implications
Two new Late Cretaceous ichnospecies are named on the basis of tracks of birds with webbed feet discovered in the Uhangri Formation, Hwangsan Basin of South Korea. The first, Uhangrichnus chuni
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
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.
