The collection and dissemination of vertebrate ichnological data is struggling to keep up with
techniques that are becoming commonplace in the wider palaeontological field. A standard …

The bipedal stance and gait of theropod dinosaurs evolved gradually along the lineage
leading to birds and at some point (s), flight evolved. How and when did these changes …

This study concerns the formation, taphonomy, and preservation of human footprints in
microbial mats of present-day tidal-flat environments. Due to differences in water content …

Abstract Terror birds (Aves, Phorusrhacidae) comprise the most outstanding group of South
American Cenozoic avifauna, and have been considered dominant predators. Terrestrial …

As purely sedimentary structures, fossil footprints are all about shape. Correctly interpreting
the significance of their surface topography requires understanding the sources of …

Fossil tracks represent a direct window onto the lives of extinct organisms, being formed and
preserved in situ. Because track morphology is determined by limb motion, foot anatomy and …

A comprehensive systematic neoichnological study was conducted to investigate the affect
of substrate conditions on the morphology and survivorship of terrestrial arthropod …

Finite-element analysis was used to investigate the extent of bias in the ichnological fossil
record attributable to body mass. Virtual tracks were simulated for four dinosaur taxa of …

The feet of ground-dwelling birds retain many features of their dinosaurian ancestry.
Experiments with living species offer insights into the complex interplay among anatomy …

Background Fossil tracks made by non-avian theropod dinosaurs commonly reflect the
habitual bipedal stance retained in living birds. Only rarely-captured behaviors, such as …
