Fossils from two species, Brasilodon quadrangularis and Riograndia guaibensis, offer important insights into the development ...

Advanced biomechanical modeling shows that early mammal ancestors likely used an eardrum to hear airborne sounds 250 million ...

One of the most important steps in the evolution of modern mammals was the development of highly sensitive hearing. The middle ear of mammals, with an eardrum and several small bones, allows us to ...

The new research is the first to look back at early mammals in full color. Using advanced fossil imaging methods and a thorough examination of the pigment-producing cells present in living mammals, ...

The Mesozoic era, traditionally renowned as the age of dinosaurs, also marks a period of remarkable innovation in the evolution of early mammals. Mammaliaforms diversified into a variety of ecological ...

One of the most important steps in the evolution of modern mammals was the development of highly sensitive hearing. The middle ear of mammals, with an eardrum and several small bones, allows us to ...

While many dinosaurs and pterosaurs flaunted flamboyant feathers, early mammals were a dull lot. A study of the fossilised fur of six mammals that lived during the Jurassic and Cretaceous periods has ...

Researchers reveal new insights into the complex evolutionary history behind the distinctive upright posture of modern placental and marsupial mammals, showing the transition was surprisingly complex ...

According to most experts, the first mammal was Morganucodon, a small, shrew-like rodent that appeared during the Jurassic Period, approximately 200 million years ago. It weighed a few ounces and ...

The discovery of new cynodont fossils from southern Brazil by a team of palaeontologists has led to a significant breakthrough in understanding the evolution of mammals. These fossils, belonging to ...

Mammals, including humans, stand out with their distinctively upright posture, a key trait that fueled their spectacular evolutionary success. Yet, the earliest known ancestors of modern mammals more ...
