最近,在世界上开始发现了有栉动物(栉水母类)化石(G·D·stanley,Jr,和W·sturmer,1983)据发现,化石在西德产出于早期泥盆纪的粘板岩中.在这种岩石中迄今已发现了将近370种无脊椎动物化石,这个栉水母也和那些化石一样.它的有机硫黄成分为黄铁矿所置换,因此软体部分形态被保存下来,这已通过X射线法查出.此栉水母化石现已命名为Paleoctenopborarasseli,呈放射对称的卵形,体长13mm,直径 Recently, the discovery of fossils of comblike animals in the world (G. Stanley, Jr., and W. Sturmer, 1983) found that the fossils were produced in the early Devonian slate in West Germany To date, nearly 370 invertebrate fossils have been found in this rock, the same as those fossils, whose organosulfur composition is replaced by pyrite, and the morphology of the soft parts has been preserved X-ray method to detect this comb Jellyfish fossils now named Paleoctenopborarasseli, was radially symmetrical oval, body length 13mm, diameter
