Marrella splendens

Cambrian

Burgess Shale, Stephens Formation

Field, British Columbia BC Canada.

14mm iconic Burgess Shale specimen.

Arthropod.

Marrella is an extinct genus of arthropod apparently found only in the Burgess Shale although related forms (marrellamorphs) are known from elsewhere in place and in time.

While it’s been said to be most common animal in the Burgess Shale, that doesn’t mean it’s easy to find on the market.  Demand has been higher than supply since the 90’s.
