‘Staring at me:’ Oldest known spider ancestor found in Burgess Shales

Alberta’s famed Burgess Shales have yielded another ground-breaking fossil find — this time the oldest known ancestor of today’s spiders and scorpions

Two scientists from the Royal Ontario Museum pried loose the well-preserved 500-million-year-old fossil from the area’s abundant deposits.

They describe the thumb-sized beastie as a fierce predator, equipped with tiny pincers in front of its mouth to grab, kill and eat its prey.

It’s those pincers that put it at the root of a family tree that now boasts more than 115,000 different species.
