Unlike the living sperm whale, which has no functional teeth, the ancient Livyatan melvillei, with its 36 cm. teeth feeds on other whales and bigger predators.
Stegodon dinosaurs are thought to be prehistoric cousins of modern elephants. A team of scientists in Pakistan recently unearthed a 1.1 million-year-old tusk belonging to one of these prehistoric animals in a central province of Punjab.
Rare fossils recently found in Idaho represent at least three new small to mid-sized species of theropod, which is the group of carnivorous dinosaurs that includes the Tyrannosaurus rex.
Fossils of a giant, flightless bird have finally been analyzed, and confirm a prehistoric species known as Gastornis roamed the Arctic 53 million years ago. While the climate was much different then, scientists warn that climate change could one day invite more diverse species to the North.
A new species of dinosaur thought to be the oldest Jurassic dinosaur ever found in the U.K. was named Dracoraptor hanigani or “dragon robber." Researchers say this find is remarkably valuable, as it sheds light on the diversification of dinosaurs in the early Jurassic – a period that remains rather hazy to paleontologists.
Mammals have evolved much more sensitive hearing than their reptile-like ancestors thanks to three super tiny bones tucked away in the auditory canal. But researchers are still unsure how the mammalian middle ear evolve. Now the University of Queensland (UQ), is shedding some light on the matter, challenging current beliefs and calling for further fossil evidence.
A frozen mammoth carcass excavated from the Siberian Arctic had several spear-related injuries, which suggests humans arrived in the area 10,000 years earlier than previously thought.
Fossils of a 508 million-year-old shrimp-like creature known as "Waptia" were discovered in China carrying several eggs with embryos. This find represents the earliest known evidence of brood care, researchers say.
Fossils excavated from the fossil-rich Bighorn Basin in Wyoming shed new light on the different physical and behavioral traits of early carnivorous mammals known as hyaenodontids.
Scientists have discovered a new member of the Ceratopsia dinosaur family, but it lacked horns and was the size of a small dog.
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.
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.
A fossil species of baleen whales sheds new light on the transition from ancient toothed whales to modern baleen whales.
