Omnidens
http://dbpedia.org/resource/Omnidens
Omnidens amplus, meaning "large all-tooth", is an extinct species of large Cambrian animal known only from a series of large mouth apparatus, originally mistaken as the mouthparts of anomalocaridids. When first named, it was interpreted as a giant priapulid, but is now considered a panarthropod. Its mouth apparatus closely resembles that of the smaller gilled lobopodian Pambdelurion, indicating it is likely to have been a close relative of that species, with which it may be synonymous. With a maximum estimated body length of 1.5 metres (4.9 ft), Omnidens is suggested to have been the largest known free-living Cambrian organism. Omnidens fossils are found in the Maotianshan Shales.

全牙虫属（學名：Omnidens）是寒武纪期间的一属大型动物，模式种是大全牙虫（Omnidens amplus）。全牙虫现已灭绝，人们只能通过在帽天山页岩遗留下来的几片口器化石推测其形态。人们曾误认为其口器化石属于放射齿目动物，首次发现时，科学家认为全牙虫是一种鳃曳动物，但现在又划成泛节肢动物。其口器很像长有鳃的口器，意味着这两种动物很可能是近亲。据推测，全牙虫体长可达1.5米，是目前已知最大的自由生活的寒武纪生物之一。
