|  Description:
This unusual arthropod is known as Isoxys The species is known mostly
from the distinctively–pointed bivalved carapace as seen here.
The taxon is only rarely preserved with any soft parts evident.
Based upon the few known examples, it had a  long
segmented body, forwardly-projecting stalked eyes, and short antennae.
This fine specimen comes from what has been termed the “Guanshan
Fauna”, found in the Wulongqing Formation. The Guanshan Fauna
shares many genera with the slightly older Chengjiang Biota, but
differs at the species levelThe swimming appendages and most other
soft parts only protruded slightly from their protective shell.
It is known also from the Chengjiang Biota, while other members
of the genus are found in deposits in Europe, Australia, and North
America.
