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.
