Vauxia gracilenta is a species of sponges found from the Burgess Shale of the Middle Cambrian, and was first described by Charles D. Walcott 1), 2).
Vauxia is a cylindrical or elongated conical shape, an unbranched or branched form, and about 8cm high 1), 2). Like many other sponges, Vauxia was presumably sessile (attached to the sea floor) and fed on organic matter filtered from seawater 1).
Vauxia #2
Vauxia was placed in the hexactinellids (Class Hexactinellida), however, was later reassigned to the demosponges (Class Demospongiae) 1).
The generic name "Vauxia" is named after Mount Vaux, a mountain in Yoho National Park, British Columbia, Canada, and the specific name "gracilenta" is derived from the Latin "gracilis", meaning "slender" 1).
