500 million-year-old fossil is the earliest branch of the spider’s lineage

Quick Summary:

A local fossil collector in Morocco found the specimen decades ago.

It holds great significance, because “the origin of chelicerates has been one of the most tangled knots in the arthropod tree of life, as there has been a lack of fossils between 503 to 430 million years ago,” Gueriau added.

The study from Gueriau and his team is the first to describe S.abundantis and its connection to modern-day chelicerates (also called euchelicerates).
