Three bones in our middle ear help amplify sound. Hadrocodium, a small mouse-like creature that descended from reptiles some million year ago, was one of the first critters to inherit the special three-boned ear.

As late reptiles and early mammals developed whiskers and a better sense of hearing, their brains had to process more information. Because of this, their brains started to grow. Most modern reptiles have long, sharp, peg-shaped chompers think crocodiles. The dog-like lizard gorgonopsid was one of the first ancient reptiles to flaunt long, saber-toothed canines.

With this discovery, the evolutionary kink disappears. All amniotes — creatures that have an extra membrane or barrier around their eggs, including most mammals, birds and reptiles — can trace their lineage back to a common reptilian ancestor. This includes bearded dragons, chickens, mice, and humans, just to name a few. Jacob Musser, an evolutionary biologist at the European Molecular Biology Laboratory in Germany, was one of the researchers behind the molecular placode camp.

He says these findings provide important information about the evolutionary development of placodes. It may not have been a scale. But the researchers said the newly discovered creature is different enough to justify having its own genus and species: Bonacynodon schultzi.

The other newfound cynodont species, also discovered in the state of Rio Grande do Sul, was identified from fewer remains—just a jaw with teeth , the researchers said. The scientists dubbed it Santacruzgnathus abdalai, in honor of Fernando Abdala, an Argentinian paleontologist who studies South American and African cynodonts, the researchers said. The shape and dentition of S. However, both cynodonts lived millions of years before the appearance of the first known mammal: a shrew-like creature that lived about million years ago in what is now China, experts told Live Science in The new study was published online today Oct.
