Palaeontology

They are among the largest predators ever to walk the Earth, but experts have discovered that some baby tyrannosaurs were only the size of a Border Collie dog when they took their first steps.

Simon Fraser University researchers have found evidence that large ambush-predatory worms--some as long as two metres--roamed the ocean floor near Taiwan over 20 million years ago.

Researchers from the University of Cambridge have discovered a fossil of the earliest starfish-like animal, which helps us understand the origins of the nimble-armed creature.

The fossilized insect is tiny and its genital capsule, called a pygophore, is roughly the length of a grain of rice.

New study identifies a bizarre new species suggesting that giant marine lizards thrived before the asteroid wiped them out 66 million years ago.

Bioluminescence has fascinated people since time immemorial. The majority of organisms able to produce their own light are beetles, specifically fireflies, glow-worm beetles, and their relatives.

New research indicates adolescent offspring of the menacing sabre-toothed predator, Smilodon fatalis, were more momma's cubs than independent warriors.

New research by scientists at the University of Bristol explains how a 'stop-start' pattern of evolution, governed by environmental change, could explain why crocodiles have changed so little since the age of the dinosaurs.

The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants that they relied on for food.

Palaeontologists at the University of Bonn (Germany) have succeeded in reconstructing the chewing motion of an early mammal that lived almost 150 million years ago.

New research published today in the Journal of Vertebrate Paleontology describes a bizarre 66 million-year-old mammal that provides profound new insights into the evolutionary history of mammals from the southern supercontinent Gondwana - recognized today as Africa, South America, Australia, Antarctica, the Indian subcontinent, and the Arabian Peninsula.

The discovery of the first known fossil iguana nesting burrow, on an outer island of the Bahamas, fills in a gap of scientific knowledge for a prehistoric behavior of an iconic lizard.
