The Drumian Wheeler Konservat‐Lagerstätte of the House Range of Utah (Wheeler‐HR) has yielded one of the most diverse exceptionally preserved Cambrian biotas of North America. The discovery of soft‐bodied fossils invariably provides precious insights into this biota, given that most of its non‐biomineralizing components are known from very few specimens. This contribution describes some 30 new exceptionally preserved fossils of Wheeler panarthropods. Two new species are recognized, the radiodont Hurdia sp. nov. A and the megacheiran Kanoshoia rectifrons gen. et sp. nov. Along with a species of Leanchoilia,K. rectifrons represents the first confident megacheiran record in these strata. The presence of the radiodont genus Amplectobelua and the isoxyid species Isoxys longissimus is reported outside of the Burgess Shale in Laurentia. New specimens of Caryosyntrips serratus,Naraoia compacta,Messorocaris magna and Mollisonia symmetrica provide insights into the phylogenetic affinities, local spatial distribution and morphological variation of these species hitherto known by single specimens in the Wheeler‐HR. The same is true of new materials of the more common Pahvantia hastata and Perspicaris? dilatus. Formal descriptions of the order Mollisoniida ord. nov. and family Mollisoniidae fam. nov. are also provided. Last, the preservation of body structures other than the dorsal exoskeletons is illustrated for the first time in two common components of the fauna: the agnostid Itagnostus interstrictus and the bivalved euarthropod Pseudoarctolepis sharpi. The new material substantially improves our understanding of the diversity of the Wheeler‐HR biota, and provides new evidence of its distinctiveness relative to the Wheeler biota of the Drum Mountains.

来自犹他州众议院山脉的德鲁米·惠勒·康维尔特·拉格斯塔特的新保存的特别节肢动物

犹他州众议院（Wheeler-HR）的Drumian WheelerKonservat-Lagerstätte已成为北美保存最为完整的寒武纪生物之一。鉴于大多数非生物矿化成分是从很少的标本中得知的，因此，对软化石的发现总是提供了对该生物群的宝贵见解。该文稿描述了惠勒（Wheeler）兽足节肢动物的大约30种新的特有保存的化石。确认了两个新物种，radiondont Hurdia sp.。十一月 A和megacheiran Kanoshoia rectifrons gen。等。十一月 连同Leanchoilia的一个物种，K。rectifrons代表了这些地层中的第一个有信心的巨型奇兰人记录。放射菌属的存在劳伦提亚的伯吉斯页岩以外据报道有两栖动物和长寿类异氧基。迄今仅由惠勒HR中的单个标本已知的这些物种的亲缘关系，局部空间分布和形态变异提供了洞悉的Caryosyntrips serratus，Naraiaia compacta，Messorocaris magna和对称Mollisonia的新标本。更常见的Pahvantia hastata和Perspicaris的新材料也是如此吗？扩张。Mollisoniida ord订单的形式描述。十一月 和家人Mollisoniidae家族。十一月 还提供。最后，首次在动物区系的两个常见组成部分中说明了除背外骨骼以外的身体结构的保存：无知觉的间断Itagnostus interstrictus和双壳类真人节肢动物Pseudoarctolepis sharpi。新材料极大地增进了我们对Wheeler-HR生物群多样性的理解，并提供了相对于鼓山Wheeler生物群独特性的新证据。
