Yuknessia sp.
Vendor: Gold Bugs
SKU Number: SQ5654277
Burgess Shale Fauna from Utah includes the rare pterobranch Yuknessia sp. It was originally classed as a green alga, but has since been reinterpreted as a colonial pterobranch. These are hemichordate worm shaped animals. Hemichordates appear in the Lower or Middle Cambrian and include two main classes: Enteropneusta (acorn worms are detritus feeders, eating sand or mud and extracting organic detritus), and Pterobranchia (small colonial worm-like filter-feeders). Also on the plate to the left is a Margaretia sp., a large green algae frond.

Additional Information
Yuknessia is a Burgess Shale fauna from the Cambrian Period that is also found in the Wheeler Shale Lagerstätte of Utah.
Yuknessia belongs to the the class: Pterobranchia, a group of small worm-shaped animals. They belong to the Hemichordata, and live in secreted tubes on the ocean floor. Pterobranchia feed by filtering plankton out of the water with the help of cilia attached to tentacles.
