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 …

The landscapes and seascapes of Earth's surface provide the theatre for life, but to what
extent did the actors build the stage? The role of life in the long-term shaping of the …

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 …

To be able to distinguish between true tracks, undertracks and tracks altered by erosion is of
great importance in tetrapod track ichnotaxonomy. This paper reports three experimental …

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 …

Triassic tetrapod footprints have a Pangaea-wide distribution; they are known from North
America, South America, Europe, North Africa, China, Australia, Antarctica and South Africa …

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 …

This study describes a set of theropod footprints collected from the Late Jurassic Lastres
Formation (Asturias, N Spain). The footprints are natural casts (tracks and undertracks) …

Whilst bones present a static view of extinct animals, fossil footprints are a direct record of
the activity and motion of the track maker. Deep footprints are a particularly good record of …
