The new invertebrate trace fossil from paleosols of the Bijori Formation, Palliedaphichnium gondwanicum new ichnogenus new ichnospecies, which belongs to an upper Permian Gondwana sequence of India, makes a significant contribution to the meager records of invertebrate trace fossils from Permian and Indian paleosols. This trace fossil attributed to Diplopoda and composed of tunnels and chambers filled with pellets is also an important addition to the scarce record of Permian millipedes. The abundance of plant remains in the same paleosol indicates that these millipedes probably fed on leaf litter as other fossil and extant representatives. Chambers and abundant pellets in burrows indicate adverse conditions on the surface, at least seasonally. This finding contributes to the emerging scenario of invertebrate ichnofaunas from paleosols and points to a successive dominance of millipedes during the Paleozoic, crayfishes and earthworms in the Mesozoic, and insects in the Cenozoic.UUID: http://zoobank.org/4378c739-9bd1-4382-b084-e2176045e209

Palliedaphichnium gondwanicum new ichnogenus new ichnospecies,一种来自印度上二叠纪冈瓦纳序列古土壤的千足虫踪迹化石

来自Bijori组古土壤的新无脊椎动物踪迹化石,冈瓦尼甲虫new ichnogenus new ichnospecies 属于印度上二叠纪冈瓦纳序列,对二叠纪和印度古土壤无脊椎动物踪迹化石的微薄记录做出了重大贡献。这种属于双足纲的痕迹化石,由充满颗粒的隧道和腔室组成,也是二叠纪千足虫稀有记录的重要补充。同一古土壤中的大量植物表明这些千足虫可能与其他化石和现存代表一样以落叶为食。洞穴中的房间和丰富的颗粒表明地表的不利条件,至少是季节性的。这一发现有助于从古土壤中出现无脊椎动物的鱼类,并指出古生代千足虫、中生代小龙虾和蚯蚓的连续优势,http://zoobank.org/4378c739-9bd1-4382-b084-e2176045e209
