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.
By analyzing the DNA of Homo floresiensis' teeth, researchers found that they were a separate species from modern man.
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.
Scientists have looked at a mass extinction that occurred 359 million years ago and have found that it caused the die-off of large species while smaller species survived.
Scientists have recovered 520-million-year-old brain fossils, which is shedding light on the fossilization of the brain, which was considered to be impossible for many years by scientists.
Researchers have found fossils belonging to the largest rats that ever lived. The fossil samples revealed evidence that these rats were ten times bigger than modern rats, according to a team of researchers from the Australian National University.
