Abstract Morphology of keratinised toe pads and foot scales, hinging joints claw shape size all inform the grasping ability, cursoriality feeding mode living birds. Presented here is morphological evidence from fossil feet early theropod flyers. Foot soft tissues joint articulations are qualitatively assessed using laser-stimulated fluorescence. Pedal quantitatively analysed traditional morphometrics. We interpret these data among existing to better understand evolutionary ecology Jurassic...
Abstract Epidermal scales in sauropsids perform a wide array of biological functions, which can relate to their shape and size. Accordingly, growth‐related changes scale morphology may reflect distinct functions between juvenile adult individuals, such as use mating interactions. Such patterns are poorly explored both extant reptiles non‐avian dinosaurs, limiting functional interpretations. Here, we investigate growth the ornithischian ceratopsid Chasmosaurus belli hadrosaurid Prosaurolophus...
The Wapiti Formation of northwest Alberta and northeast British Columbia, Canada, preserves an Upper Cretaceous terrestrial vertebrate fauna that is latitudinally situated between those documented further north in Alaska from southern the contiguous U.S.A. Therefore, important for identifying broad patterns ecology, diversity, distribution across Laramidia during latest Cretaceous. Tracksites are especially useful as they provide a range palaeoecological, palaeoenvironmental, behavioural...
Fossil tracks should theoretically capture differences in pedal anatomy between growth stages of the same taxon, particularly those related to soft tissue foot, providing a more realistic view ontogeny than skeletal material alone. However, recognizing these ontogenetic trajectories is complicated by influence preservation and kinematics on track morphology, as well inherent difficulty referring different single taxon. Here, we explore morphology from collection attributed tyrannosaurids...
Abstract Late Cretaceous tracks attributable to deinonychosaurs in North America are rare, with only one occurrence of Menglongipus from Alaska and two possible, but indeterminate, occurrences reported Mexico. Here we describe the first probable deinonychosaur Canada: a possible trackway isolated track on single horizon Upper Wapiti Formation (upper Campanian) near Grande Prairie Alberta. The presence relatively short digit IV differentiates these argued dromaeosaurid tracks, suggesting...
