Early human relative predates even dinosaurs

The world's first known tree-dwelling vertebrate has just been identified, according to a new study. The tiny, agile animal lived 30 million years before the first dinosaurs and was a distant relative of mammals, including humans.

More than 15 near-complete skeletons of the 260-million-year-old animal, named Suminia getmanovi, reveal that it was built for an arboreal lifestyle.

"As the first tree-climbing vertebrate, Suminia had very long fore and hind limbs, with especially long hands and feet," lead author Jorg Frobisch told Discovery News.
