"An Early Cambrian Lophophorate Animal with affinities to Brachiopods and Phoronids.
Lophophorates are animals which feed using a filter called a lophophore, which comprises a number of setae covered tentacles, to extract food from water. The group includes the shelled Brachiopods, the worm-like Phoronids, the minute Entoprocts, and colonial Bryozoans, and has been shown by molecular and embryonic evidence to be related to the Molluscs and Annelids. Within the Lophophorates the Phoronids and Brachiopods are thought to be closely related, with some studies suggesting that the Phoronids should be regarded as a shell-less subgroup of the Brachiopods."
