A fossil uncovered on a farm in China could be the oldest known species from the bird family. This 150-million-year-old fossil was a small feathered dinosaur, a little over three feet tall, named Aurornis xui. Scientists are still in controversy over whether this specimen does qualify as a bird, but if it does than it will be the oldest of the long line of the evolution of birds and flight.

For years, scientists have been disputing about the timing of the first appearance of rodents on Earth.
Recent discoveries of two new fossils are evidence that the earliest rodent species began about 57.7 to 58.9 million years ago. Being one of the most diverse species on earth, this rodent discovery is monumental for scientists to continue to determine the first origins of placental mammals.
