Since it was found in 1911, an Egyptian iron bead has sparked wonder and debate over how it was produced — made around 3,300 BC, it predates the region's first known iron smelting by thousands of years. Now, researchers say the iron was made in space and delivered to Earth via meteorite.
You know what they say about the early bird? Well, a new species is vying for that title. Scientists have long-regarded an ancient creature, known as the Archaeopteryx, as the earliest bird known to science. But a discovery made in China could change that, according to a study published in Nature magazine. Scientists have found evidence of a feathered, chicken-sized species that's 10 million years older. It's called Aurornis xui, and it lived about 160 million years ago.
Move over Archaeopteryx, an older bird just landed on the evolutionary tree.
Scientists writing in Nature magazine, say a feathered, chicken-sized creature known as Aurornis xui, unearthed recently in northeastern China, challenges the "pivotal position of Archaeopteryx" — long regarded as the oldest bird.
