The basal ornithopod Oryctodromeus cubicularis was described as burrowing due to its
discovery in a burrow structure, and the presence of several morphological features …

Minimal direct evidence exists in the rock record of dinosaurs and mammals behaving as
predators and prey, respectively. A newly discovered Late Cretaceous trace fossil …

Insect trace fossils, such as burrows, pupation chambers and nests, can provide broad
paleoecological insights by helping to define paleohydrology, effects of seasonality or …

How far back can we trace behaviour associated with pain? Behaviour is not preserved in
the palaeontological record, so, for dinosaurs, we are restricted to what we can deduce from …

Abstract The Lujiatun Unit (Yixian Formation) yields some of the most spectacular vertebrate
fossils of the Jehol Group (Lower Cretaceous) of NE China. Specimens are preserved both …

Ornithopod dinosaurs were bipedal, herbivorous dinosaurs represented in the Late
Cretaceous of North America by basal ornithopods (“hypsilophodontids”) and a clade of …

This study includes the first neoichnologic characterization of the burrow systems of
