Summary:
Researchers have described an
exceptionally well-preserved new fossil species of bristle worm called Kootenayscolex barbarensis. Discovered
from the 508-million-year-old Marble Canyon fossil site in the Burgess Shale in
Kootenay National Park, the new species helps rewrite our understanding of the
origin of the head in annelids, a highly diverse group of animals which
includes today's leeches and earthworms.
