From collection of B. PoelkerEssexella asherae is a scyphomedusan jellyfish. Like modern jellyfish, these animals would have captured and eaten smaller animals using stinging cells (nematocysts).
The fossil shows the animal's manubrium (bell) and what Foster (1979) identifies as a skirt that surrounded the tentacles and oral lobes.
