The missing link in the evolution of spiders found trapped in amber

An ancient creature, half spider, half scorpion, dating from the Cretaceous era, has been found trapped in amber and it may offer valuable insights about the evolution of spiders. Four specimens, about 100 million years old, have been thoroughly studied and they are the subject of two independent scientific studies. The arachnids have a distinct anatomy resembling a spider with tail, suggesting that early in evolution spiders had a mix of anatomical traits. These fossils likely represent the earliest evolutionary branch of the arachnids.
