Researchers have identified a ceratopsian dinosaur from 160 million years ago that has an "ornamental" head.
Researchers have discovered the fossil of an early mammalian carnivore known as 'hyaenodontids' a species which dates back to about 50 million years ago. The fossil was found in the Bighorn Basin in Wyoming.
Researchers have identified a strange extinct three-horned giraffe-like fossil, which was found in Spain. The animal is a distant giraffe relative that roamed Eurasia between 11 to 16 million years ago.
Researchers have identified a 30-million-year-old baleen whale fossil that once lived in the North Pacific Ocean. The whale fossil is shedding light on the evolution of baleen whales.
A rare dog-sized fossil of a horned dinosaur has been identified by researchers. The unusual fossil dated to the Cretaceous period, around 66-100 million years ago.
Researchers are studying the porosity of archosaurs' eggshells, which is revealing new evidence on the types of nests that the archosaurs built.
Scientists have found that periods of high extinction on Earth have been the drivers of the diversification of amniotes, which include today's land vertebrates, such as reptiles, birds, and mammals.
A study at the University of Leeds is revealing new evidence on the mass extinction period on the earth.
Without us, pumpkins and squashes may have gone extinct in North America.
Extinction may actually spread from predator to predator. Scientists have found that the extinction of one carnivore species can trigger the demise of fellow predators.
Researchers found that sharks and other large marine predators are losing their hunting abilities due to warmer oceans and high levels of CO2. This reduces sharks' growth and development, and their population declines at the same time.
