Tamisiocaris (from Latin tamisium, sieve, and Greek karis, crab, shrimp) is a radiodont genus initially only known from frontal appendages from the Cambrian Sirius Passet lagerstatte in northern Greenland. It was initially described initially in 2010.[1] Further study in 2014 revealed that the frontal appendages were segmented and bore densely packed auxiliary spines, which were adapted to suspension feeding in a manner analogous to modern baleen whales.[2] It is assigned to the family Tamisiocarididae, and is measured about 34 cm (1.12 ft) long in total body length.[3]
