Tamisiocaris
Extinct genus of marine animals
From Wikipedia, the free encyclopedia
Tamisiocaris (from Latin tamisium, sieve, and Greek karis, crab, shrimp) is a radiodont genus from the Cambrian period. The taxon was initially described in 2010 based on frontal appendages discovered from the Sirius Passet lagerstatte in northern Greenland.[1] A subsequent study by Vinther and colleagues 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.[1] It is assigned to the family Tamisiocarididae, and is measured about 22.8–33.6 cm (0.75–1.10 ft) long.[2]
