Tamisiocaris

Tamisiocaris (from Latin tamisium, sieve, and Greek karis, crab)[1] is an anomalocaridid taxon initially only known from frontal appendages from the Buen Formation in Sirius Passet. Further specimens revealed that the frontal appendages were segmented and bearing densly-packed auxiliary spines, which were adapted to suspension feeding in a manner analogous to modern baleen whales.[2]
