15-07-21 Mammals were evolving up to ten times faster in the middle of the Jurassic than they were at the end of the period, coinciding with an explosion of new adaptations, new research shows. Early mammals lived alongside the dinosaurs during the Mesozoic...
15-06-08 When it comes to the three-horned dinosaur called the Triceratops, science is showing the ancient creatures might have been a little more complex than we thought. In fact, their teeth were far more intricate than any reptile or mammal living today....
15-03-03 You might resemble or act more like your mother, but a novel research study from UNC School of Medicine researchers reveals that mammals are genetically more like their dads. Specifically, the research shows that although we inherit equal amounts of...
14-10-09 The discovery of new bones from a large land mammal that lived about 48 million years ago has led scientists to identify a new branch of mammals closely related to modern horses, rhinos, and tapirs, according to a study published October 8, 2014 in...
14-07-09 The Earth has experienced many dramatic changes in climate since the dinosaurs went extinct 66 million years ago. One of the warmest periods was the early Eocene Epoch, 50 to 53 million years ago. During this interval, North American mammal communit...
