A shelled fossil discovered in an amateurâ€™s collection may harbor the first direct evidence of prehistoric sharks eating ammonites some 150 million years ago. The palm-sized ammonite, an extinct marine animal and distant relative of the modern nautilus, was fossilizedâ€¦

Modern whale strandings can be investigated and their causes identified. Events that happened millions of years ago, however, are far harder to analyze â€” frequently leaving their cause a mystery.
Scientists examined a large fossil site in the Atacama Desert of Northern Chile â€” the first definitive example of repeated mass strandings of marine mammals in the fossil record. It reflected four distinct strandings over time, indicating a repeated and similar cause: toxic alga

The first top predators to walk on land were not afraid to bite off more than they could chew, a study has found. Researchers suggest that Dimetrodon, a carnivore that walked on land between 298 million and 272 million years ago, was the first terrestrial vertebrate to develop serrated ziphodont teeth.

In the remote province of Niassa, Mozambique, a new species and genus of fossil vertebrate was found. The species is a distant relative of living mammals and is approximately 256 million years old.
This new species belongs to a group of animals called synapsids. Synapsida includes a number of extinct lineages that dominated the communities on land in the Late Permian (260-252 million years ago), as well as living mammals and their direct ancestors.

A new species of carnivorous dinosaur â€“ one of the three largest ever discovered in North America â€“ lived alongside and competed with small-bodied tyrannosaurs 98 million years ago. Siats meekerorum, (pronounced see-atch) was the apex predator of its time.

Amber provides new insights into the evolution of Earth's atmosphere: Low oxygen levels for dinosaur
Scientists have reconstructed the composition of the Earthâ€™s atmosphere of the last 220 million years by analyzing modern and fossil plant resins. The results suggest that atmospheric oxygen was considerably lower in the Earthâ€™s geological past than previously assumed. This new study questions some of the current theories about the evolution of climate and life, including the causes for the gigantism of dinosaurs.
