Permian millipedes are rare, especially so considering the relative abundance of millipedes in Carboniferous rocks. We report an early Permian millipede fauna containing three new genera and species of millipedes (Oklahomasoma richardsspurense new genus new species, Karstiulus fortsillensis new genus new species, and Dolesea subtila new genus new species) found in fossil-producing pockets of the Fort Sill fissures exposed in the Dolese Quarry near Richards Spur, southwest Oklahoma, USA. These are the first new genera of invertebrates to be described from this site, one of the most prolific fossil-vertebrate sites in the world. We also comment on taxa with morphological similarities and note previously described occurrences of Permian millipedes as well as occurrences of fossil myriapods (millipedes and centipedes) in karst deposits (caves and fissure fills) in Europe, Africa, Asia, North America, and the Caribbean. In contrast with the forms found at Richards Spur, most of these previous accounts of millipedes found in caves and fissure fills are of Pleistocene forms that are closely allied to modern taxa. The taxa from Richards Spur bear some similarities to Pennsylvanian forms. Karst (cave and fissure) faunas should be ranked with concretion faunas, cannel coals, and amber faunas as a major source of fossil myriapods.UUID: http://zoobank.org/5d58e1fb-4e5b-4597-9cd9-5cc9e2096b4d

来自俄克拉荷马州西南部 Fort Sill 裂缝的二叠纪千足虫,对在喀斯特环境中保存的同属类群和千足虫的评论

二叠纪千足虫很少见,尤其是考虑到石炭纪岩石中千足虫的相对丰度。我们报告了一个早二叠纪千足虫动物群,其中包含三个新的千足虫属和种(俄克拉荷马州理查兹斯普伦斯新属新种,福寿螺新属新种,和枯草新属新种)在美国俄克拉荷马州西南部理查兹斯普尔附近的 Dolese 采石场暴露的 Fort Sill 裂隙的化石产区中发现。这些是从该地点描述的第一个新的无脊椎动物属,该地点是世界上最多产的化石脊椎动物地点之一。我们还评论了具有形态相似性的分类群,并注意到先前描述的二叠纪千足虫的出现以及在欧洲、非洲、亚洲、北美和加勒比地区的喀斯特沉积物(洞穴和裂缝填充物)中出现的化石多足类动物(千足虫和蜈蚣) . 与在理查兹马刺发现的形态相比,这些先前在洞穴和裂缝填充物中发现的千足虫的大部分都是与现代分类群密切相关的更新世形态。理查兹马刺的分类群与宾夕法尼亚形式有一些相似之处。喀斯特(洞穴和裂隙)动物群应与结核动物群、煤岩和琥珀动物群作为化石多足类动物的主要来源进行排名。UUID:http://zoobank.org/5d58e1fb-4e5b-4597-9cd9-5cc9e2096b4d
