The skeletal anatomy of the triassic protorosaurDinocephalosaurus orientalisLi, from the Middle Triassic of Guizhou Province, southern China

AbstractStudies of Triassic insects in China began in 1956, and so far, a total of 89 genera and 109 species have been found from the Triassic of China. The fossil records are from 17 provinces (or regions) in China are assigned to 11 orders except for two genera and species considered incertae sedis in Insecta. These Chinese Triassic insects including one Early Triassic, 53 Middle Triassic and 55 Late Triassic species are briefly reviewed in taxonomy and distribution, and listed here with detailed taxonomic and stratigraphic information. The Middle Triassic Tongchuan Entomofauna and Late Triassic Toksun Entomofauna are introduced much detailed from the perspectives of composition and taxonomy. Existing data indicate that the Chinese Triassic entomofauna is dominated by Hemiptera, Mecoptera and Coleoptera; the Chinese Early Triassic insects are only known from Fuyuan in Yunnan Province, Middle Triassic ones mainly known from northern China and sporadically from Guizhou Province, southern China, and Late Triassic ones widely seen in both northern and southern China; and the Middle and Late Triassic entomofaunas are similar in abundance but show a pattern of “more in northern China than in southern China”.

The Way

Limestone areas of China host remarkable radiations of cave animals. The subterranean trechine beetles (Carabidae: Trechini), the most diverse and modified group of subterranean beetles in the world, are extremely diverse in southern China. The first aphaenopsian trechine beetle, Sinaphaenops mirabilissimus Uéno & Wang, 1991 was reported from a limestone cave in Guizhou province. Up to now, 146 species within 48 genera of aphaenopsian trechine have been described in China after almost three decades. Among them, the genera Giraffaphaenops, Xuedytes, Dongodytes, Sinaphaenops and Pilosaphaenops from northwest Guangxi and south Guizhou are the most modified troglobitic trechine beetles known so far in the world. They are remarkable by their morphology combining extremely slender body and elongated appendages. Some of them are diversified or quite widespread, which is not the case of Xuedytes Tian & Huang, 2017, a remarkable monospecific genus known from a single locality so far. In addition to the surveys and collection of specimens, an integrative approach combining the study of systematics, phylogeny, diversification and biogeography patterns of the cave trechine beetles in China is on the way, in order to understand the origin of the remarkable biodiversity and evolutionary success of this group.

A New Species

A new species of glomeridellid millipede is described from Guizhou Province, southern China: Tonkinomeris huzhengkunisp. nov. This new epigean species differs very clearly in many structural details, being sufficiently distinct morphologically and disjunct geographically from T. napoensis Nguyen, Sierwald & Marek, 2019, the type and sole species of Tonkinomeris Nguyen, Sierwald & Marek, 2019, which was described recently from northern Vietnam. The genus Tonkinomeris is formally relegated from Glomeridae and assigned to the family Glomeridellidae, which has hitherto been considered strictly Euro-Mediterranean in distribution and is thus new to the diplopod faunas of China and Indochina. Tonkinomeris is re-diagnosed and shown to have perhaps the basalmost position in the family Glomeridellidae. Its relationships are discussed, both morphological and zoogeographical, within and outside the Glomeridellidae, which can now be considered as relict and basically Oriental in origin. Because of the still highly limited array of DNA-barcoding sequences of the COI mitochondrial gene available in the GenBank, the first molecular phylogenetic analysis of Glomerida attempted here shows our phylogram to be too deficient to consider meaningful.

AbstractThe ancient marine limestone beds of the upper part of the Guanling Formation, Panxian County, Guizhou Province, SW China, yielded a wide range of high-diversity well-preserved marine reptiles such as the fully aquatic protorosaur with an extremely long neckDinocephalosaurus orientalis, the oldest mixosaurid ichthyosaurs and lariosaurs. However, there is no precise isotopic age to study the intriguing origin, evolution and emigration history of the important fauna. We report a sensitive high-resolution ion microprobe (SHRIMP) U–Pb zircon age for a volcanic tuff bed within the upper part of the Guanling Formation. The result indicates that the age of the fossil horizon is 244.0±1.3 Ma, 14 Ma earlier than the previously estimated age based on conodont evidence. We consider that the marine reptiles had a relatively rapid evolution during Middle Triassic time, some 8 Ma after the end-Permian mass extinction.
