Researchers with the Royal Ontario Museum in Toronto detailed the 500-million-year-old critter for the first time in a study that is to be published Tuesday in the journal BMC Evolutionary Biology. The bizarre creature, no bigger than a thumb, lived under water in a spot that is today a shale-strewn mountain ridge in British Columbia's Yoho National Park.
The Ovatiovermis is shown in a handout photo from the Royal Ontario Museum. Researchers with the Royal Ontario Museum have for the first time identified an 18-limbed worm that lived some 500 million years ago.
Scientists on Monday said a tiny marine creature from China that wriggled in the seabed mud about 540 million years ago may be the earliest-known animal in the lengthy evolutionary path that eventually led to humans.
