Burgess Shale Burgessia Arthropod
Time: Early Cambrian (~520 million years ago)
mm long X 10 mm wide
Site: Burgess Shale Stephen Formation, Burgess Pass, British Columbia,
Bugessia bella derives its genus name from the location that
lent it name to this spectacular
window on early life and the Cambrian Explosion. It was presumably
a benthic organism that made a living crawling on the seafloor.
and so is related to both the chelicerates and trilobites.
Note the antenna, central gut, telson, and partial legs seen within
carapace. This wonderful example shows all the major features of
the taxon in incredible detail for a specimen more than a half
billion years of age.
