Nisusia is a genus of brachiopod known from the Middle Cambrian Burgess Shale. 133 specimens of Nisusia are known from the Greater Phyllopod bed, where they comprise 0.25% of the community.[1] They are the first Burgess Shale animal that are discovered by Walcott.

Included genera[]

Kutorgina[]

Kutorgina has a concavo-convex shell with the smaller brachial valve dished in and the larger pedicle valve broadly arched. The brachial valve has a rather prominent interarea at the back which is curved over by the prominent beak at the back of the pedicle valve.

It includes the species Kutorgina elanica Malakhovskaya, 2013 and K. chengjiangensis Zhang et al. 2007.

K. chengjiangensis preserves soft anatomy - pedicle, lophophore & gut.

Nisusia[]

Nisusia Walcott, 1905 (Walcott, 1889) is known from the Middle Cambrian (~508 million years ago) Burgess Shale. 133 specimens of Kutorginata are known from the Greater Phyllopod bed, where they comprise 0.25% of the community.[2]

It's a senior synonym to Orthisina alberta Walcott, 1889.

ITS pedicle emerges from between its valves, as displayed by silicified material of N. sulcate, though it still has an opening at the apex of the pedicle valve.[1]

In Popular Culture[]

In one of the brachiopods in filter feeders was a Nisusia in the Burgess Shale Rom's Virtual Sea Odyssey. It also appeared in Cambrian Seas by Phelesch Bubble.
