A study of the Serrote do Letreiro Site (meaning “Signpost Hill”) in Brazil’s Paraíba State has led to the discovery of an assemblage of petroglyphs alongside dinosaur tracks.
Birds evolved from theropod dinosaurs during the Late Jurassic period, however, our knowledge of the initial stages of Avialae's evolution is limited due to a scarcity of Jurassic fossils.
A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.
A study led by The University of Texas at Austin is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct.
Insects and terrestrial arthropods have inhabited the Earth since before the time of the dinosaurs, growing much larger to their contemporary equivalents during the Carboniferous period, due in part to a surplus of oxygen in the Earth’s atmosphere.
A preserved baby mammoth has been discovered by gold miners in the Klondike gold fields, located within the traditional tribal territory of the Trʼondëk Hwëchʼin in the Yukon, Canada.
Researchers at the University of Zurich’s Palaeontological Institute have discovered two previously unknown species related to modern sperm whales and oceanic dolphins based on a study of fossilised ear bones.
The partially fossilised remains of a giant extinct crocodilian that could have been ritualistically beheaded explain how modern crocodilian species may have evolved.
In a new study published today in the journal Royal Society Open Science, researchers present a reconstruction of the limb muscles of Thecodontosaurus, detailing the anatomy of the most important muscles involved in movement.
The fossil of a giant ichthyosaur from around 180 million years ago has been discovered at the Rutland Water reservoir in the East Midlands of England.
Researchers from the Instituto Nacional de Antropología e Historia (INAH) have identified the remains of a mammoth in the town of Los Reyes de Juárez, Mexico.
New research on a vast fossil site in Patagonia shows that some of the earliest dinosaurs lived in herds and suggests that this behaviour may have been one of the keys to the success of dinosaurs.
Sixty-three percent. That’s the proportion of mammal species that vanished from Africa and the Arabian Peninsula around 30 million years ago, after Earth’s climate shifted from swampy to icy. But we are only finding out about it now.
