Fossilised remains of human-sized 'lobster' discovered in Morocco

The newly discovered prehistoric species, named Aegirocassis benmoulae, was an early ancestor of the modern spider and the oldest giant filter-feeder on record

A filter-feeding "lobster" as big as a human took the place of whales 480 million years ago, a new fossil discovery has shown.

The two-metre prehistoric creature, whose remains were unearthed in Morocco, belonged to the family of anomalocaridids, the early ancestors of modern crustaceans, insects and spiders.
