The Burgess Shale in British Columbia, Canada, preserves numerous fossils that document the evolution of life on Earth. Among them is Habelia optata, a 508-million-year-old relative of early chelicerates. This armoured predator had five pairs of […]
The extinction of non-avian dinosaurs enabled small mammals to diversify, eventually leading to the emergence of humans. However, the disappearance of these large animals also affected the ecosystems they had inhabited for tens of millions of years. Although observing a living dinosaur would be fascinating […]
Researchers discovered an approximately 120-million-year-old assemblage of 25 dinosaur specimens in north-eastern China. One larger individual may have acted as a caregiver to the juveniles. Like other organisms, dinosaurs […]
Megalodon was the largest shark known to have existed. It appeared approximately 23 million years ago during the Miocene and could reach 18 metres in length. It was among the largest and most powerful vertebrate predators until approximately 2.6 million years ago, when it […]
Approximately 70 million years ago, during the Cretaceous, the giant frog Beelzebufo ampinga could reach 41 cm in length. Its powerful bite may have enabled it to prey on small dinosaurs. Dinosaurs were not the only large animals living at that time […]
Approximately 515 million years ago, during the Cambrian, Anomalocaris was a major marine predator. This early relative of modern arthropods could reach one metre in length and is considered one of the earliest known apex predators. The Cambrian saw the emergence of diverse and unusual […]
