A fossilized arachnid discovered in eastern France is helping researchers untangle the evolutionary roots of modern spiders. The 305-million-year-old species, named Idmonarachne brasieri, was revealed ...

One of the creepiest, crawliest creatures of the Earth may have been swimming before adapting to live on land, new research suggests. Spiders and their arachnid relatives may have actually originated ...

(PhysOrg.com) -- Pieces of amber containing parts of a spider's web have been found in East Sussex and dated back to the Cretaceous period 140 million years ago, which makes it the oldest spider's web ...

A new analysis of an exquisitely preserved fossil that lived half a billion years ago suggests that arachnids—spiders and their close kin—evolved in the ocean, challenging the widely held belief that ...

Spiders originated in the sea half a billion years ago, suggests a new study. Finely preserved brain features in a tiny marine arthropod fossil suggest that arachnids – spiders and their close kin – ...

A team of researchers have discovered the fossil of a 305 million-year-old arachnid, which will help scientists to understand more about the early origins of modern-day spiders. The new species, named ...

The 450-million-year-old fossilized corpse of a new spider species has been discovered preserved by fool’s gold. A research team from the University of Oxford discovered the fossil at Beecher's ...

Over 500 million years ago, the ancestors of a diverse group of animals known as Ecdysozoans existed. This group includes various species of insects, arachnids, and nematode worms. For a long time, ...
