Capsospongia
Extinct genus of sponges / From Wikipedia, the free encyclopedia
Capsospongia, formerly known as Corralia or Corralio, is a middle Cambrian sponge genus known from 3 specimens in the Burgess shale.[1] Its type and only species is Capsospongia undulata. It has a narrow base, and consists of bulging rings which get wider further up the sponge, resulting in a conical shape. Its open top was presumably used to expel water that had passed through the sponge cells and been filtered for nutrients.

Like most sponges, Capsospoingia had a spicular skeleton; long spicules parallel to the growth direction formed columns which were connected by shorter lateral spicules.
