Modern birds are typified by the presence of feathers, complex evolutionary innovations that
were already widespread in the group of theropod dinosaurs (Maniraptoriformes) that …

Ornithischian dinosaurs were primitively bipedal with forelimbs modified for grasping, but
quadrupedalism evolved in the clade on at least three occasions independently. Outside of …

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 …

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 …

Extensive and well-preserved tracksites in the coastally exposed Lower Cretaceous
(Valanginian–Barremian) Broome Sandstone of the Dampier Peninsula provide almost the …

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 …

This work, as a fieldtrip guide, aims to provide a glimpse into the palaeoenvironments,
palaeontology, and diagenesis of one of the most productive areas for Late Jurassic …

Here we describe a new partial sauropod skeleton from the late Kimmeridgian (Late
Jurassic) of the Lourinhã Formation, central west Portugal. The closely associated specimen …

Bone histology is an important tool for uncovering life history traits of extinct animals,
particularly those that lack modern analogs, such as the non-avian dinosaurs. In most …
