Answer: Canada
Notes: Scientists have recently discovered a new extinct species named Mosura fentoni, an early marine predator from the Cambrian period around 506 million years ago. It was found in the Burgess Shale fossil site in British Columbia, Canada, which is known for preserving ancient marine life. Mosura fentoni belongs to the group Radiodonta, which are extinct stem-group arthropods and distant relatives of modern insects, spiders, and crustaceans. Although small in size, ranging from 1.5 to 6 centimetres, it had highly specialised body features. This discovery adds to our understanding of early marine ecosystems and arthropod evolution.
