Tamisiocaris (from Latintamisium, sieve, and Greekkaris, crab, shrimp) is aradiodontgenus from theCambrian period. The taxon was initially described in 2010 based on frontal appendages discovered from theSirius 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 tosuspension feeding in a manner analogous to modernbaleen whales.[1] It is assigned to the familyTamisiocarididae, and is measured about 22.8–33.6 cm (0.75–1.10 ft) long.[2]
