This prehistoric predator, famous for its massive teeth and formidable size, dominated the seas for millions of years. Fossil evidence suggests that megal...
Researchers from the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, and several research institutions in China and the United States jointly published a study on the biology of Yanliao in the early Late Jurassic in the British journal Na...
Humans are not always good at self-control, especially when the things they face seem both rich and mouth-watering. Although species extinctions often have multiple causes, the extinction of some species can be almost directly linked to the voracious appetites of modern humans. Read on to learn abou...
In the early Eocene, a small animal called Paleoartiodactyl differentiated from the anklets. In addition to having a proximal pulley similar to that of perissodactyls, its talus also had a pulley-like distal end. It's a plane. It is this double-trochlear talus that laid the foundation for a p...
