Scientists have discovered a new member of the Ceratopsia dinosaur family, but it lacked horns and was the size of a small dog.
Cheetahs migrated to Africa from North America 100,000 years ago during the last Ice Age. Following their "big move," populations dwindled and incestuous breeding increased. This troubled linage has had a lasting impact on modern Cheetahs, many of which have difficulty reproducing due to a gene mutation that affects sperm development.
Well-preserved mosasaur fossils represent a new smallish marine reptile that used binocular vision to hunt at night.
A new species of toothy pterosaurs named Cimoliopterus dunni sheds light on the evolution of these flying reptiles. However, its closest relatives are from England, suggesting the prehistoric animals were able to "island hop" as the North Atlantic Ocean widened during the Cretaceous.
When dating volcanic ashes from the Late Triassic Period from Argentina, researchers discovered dinosaurs evolved more rapidly than previously thought. In fact, the prehistoric animals evolved roughly five million years or less after their ancestors emerged.
Some parasitic wasp species lay their eggs in the bellies of wolf spiders so that the larva can feed of the vertebrates' blood. While this does not harm the spiders initially, when the larva mature they end up killing their hosts. The recent findings highlight the diverse parasitic relationships among animals.
While there has been much debate regarding how cats first made their way to Australia, a new study has confirmed that the invasive felines arrived with European settlers in the 19th century.
Using three male and three female sand flies from a Brazilian state park, researchers have unveiled a new species of the pesky, disease-carrying bugs.
By examining the hind and forelimbs of a tiger salamanders, researchers have revealed how they may have transitioned from life at sea to life on land.
After analyzing a fossilized three-horned skull and dental remains, researchers have classified Xenokeryx amidalae as an ancient species is actually a distant relative of modern giraffes.
Mussels secrete proteins from their feet that allow them to cling to rocks in the face of powerful waves. By mimicking this technique, researchers have created a simple synthetic material that can prime and fuse two surfaces underwater.
For many species, including humans, sex is determined by sex chromosomes. However, this is not the case for ants, wasps and bees. A recent study sheds light on the evolution of sex determination in ants and how inbreeding can lead to sterile males.
A fossil species of baleen whales sheds new light on the transition from ancient toothed whales to modern baleen whales.
Scientist Magdalena Sorger has observed some previously unknown skills in a species of trap-jaw ants.
