Hexactinellid Aphrocallistes vastus.
This interpretation is further supported by the microforaminiferal content, similarly as common
hexactinellid sponges and their preservation, which is indicative of outer-platform to upper-slope environments (Astibia et al.

Although Rigby and Albi (1996) described a new species of
hexactinellid sponge from the Puente Formation in Orange County and noted that pelecypods as well as fish were present in the unit, Schoellhamer et al.
Konecki and Targett (1989) found that cod icefish, Lepidonotothen larseni (Nototheniidae), in waters adjacent to the Antarctic Peninsula utilize the spongocoel of the

Delicate, colorful corals, mother-of-pearl, and
hexactinellid sponges (or glass sponges), such as Venus' flower basket (Euplectella aspergillum), are animals much appreciated for their beauty, although none so much as the pearl of an oyster, the most valuable object by weight and size obtained from an animal.
