The fossil, collected in Antarctica in 1985, is part of the tail of a beast called a Titanosaur.

Hadrosaurid dinosaurs are generally regarded as “crested” or “non-crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non-crested” hadrosaur is known to ha...

If we taught molecular biology the way we teach statistics, we'd still be arguing whether proteins or nucleic acids were genetic material.

Recent discoveries at Roland T. Bird’s famous ‘swimming brontosaur’ tracksite on the Mayan Dude Ranch in South Texas have resulted in seven additional footprints in Bird’s original sauropod trail, ...

Fossil find reveals the earliest known short-tailed bird.

Male gharials (Gavialis gangeticus) produce loud underwater POPs by rapid jaw clapping 1–3×. POPs are temporally based, context-dependent, seasonally stable, and individually distinctive. The bulbous...
