“…Hence, the occurrence of C. zekuensis from Zeku indicates that this area had a more moderate paleoclimate with higher temperature (especially coldest month mean temperature (CMMT)) and precipitation in the Miocene than today, and the co‐occurring broadleaved woody plants (e.g., megathermic Cercis and Koelreuteria Laxmann, mesothermic Acer L., Fraxinus L., and Ulmus L.; Guo, 1980; Li et al, 2016) corroborate the existence of a warm temperate forest during the early Miocene. Rather higher historical biodiversity reflected by fossil insects (e.g., Cixius Latreille, Wesmaelius Krüger, and Helius Lepeletier & Serville; Li et al, 2017b; Yang et al, 2018; Wu et al, 2019), spiders, and birds (e.g., Passer Brisson; Young, 1975) also support this deduction. Furthermore, the inferred paleoecological trait appears to match very well the coeval regional or global climate changes from other independent proxies (e.g., geobiomarkers or isotope records; Zachos et al, 2001; Liu et al, 2014).…”

“…Thus the fossiliferous horizon can be confined to the late early Miocene. Previous publications on various fossil remains from these strata include leaves (Guo, 1980), fruits (Guo, 1980; Li et al, 2016, 2019), stems, pollen (Hui et al, 2018), insects (Li et al, 2017b; Yang et al, 2018; Wu et al, 2019), and bird feathers (Young, 1975), indicating a highly diverse biota.…”

The climatic impacts of the Tibetan Plateau since the Neogene and the phytogeographic pattern changes of formerly widely‐distributed forest communities on the plateau remain poorly constrained. Today, Cercis L. (Fabaceae) is a well‐known arborescent genus typically distributed in subtropical to warm temperate zones of the Northern Hemisphere, and Paleogene fossil occurrences from Eurasia and North America show a long history of the genus in mid‐low latitudes of the Northern Hemisphere. Here, we describe a fossil species, Cercis zekuensis sp. nov. based on well‐preserved fruits from the early Miocene of the northeastern Tibetan Plateau. Detailed morphological comparison (e.g., ventral margin with a veinless wing) of extant and fossil members of Cercis and other genera confirmed validity of the present taxonomic identity. Based on the comparison with extant relatives and their climate preferences, this unexpected occurrence of thermophilic Cercis in northeastern Tibetan Plateau indicates this area had higher temperature and precipitation in the Miocene than today. Integrated with inferred (paleo‐)temperature lapse rates, this indicates a low paleoelevation of less than 2.4 km. In contrast with the present‐day alpine climate here (~3.7 km), such a low elevation facilitated a more favorable habitat with comparatively high biodiversity and warm temperate forests at that time, as were evidenced by co‐occurring megafossils. Moreover, the present existence of Cercis implies the genus was widespread in interior Asia during the early Neogene and shows its modern disjunction or diversification between eastern and central Asia was possibly shaped by the late Cenozoic regional tectonic uplift and consequential environmental deterioration.

A crane fly of the genus Gynoplistia Macquart (Diptera, Limoniidae) from the early Miocene of New Zealand

The first fossil limoniid fly from the Miocene Fossil-Lagerstätte of Foulden Maar in New Zealand is described on the basis of an isolated well-preserved wing. The specimen is tentatively attributed to a new species Gynoplistia fouldensensissp. nov. in the large extant genus Gynoplistia, which is well diversified in the country. It is the second fossil record of this genus, the first one being an isolated wing from the Cretaceous Weald Clay Formation in the United Kingdom.

First record of the genus Helius—long-rostrum cranefly from Maestrazgo Basin (eastern Spain, Iberian Penisula) is documented. Two new fossil species of the genus Helius are described from Cretaceous Spanish amber and compared with other species of the genus known from fossil record with particular references to these known from Cretaceous period. Helius turolensis sp. nov. is described from San Just amber (Lower Cretaceous, upper Albian) Maestrazgo Basin, eastern Spain, and Helius hispanicus sp. nov. is described from Álava amber (Lower Cretaceous, upper Albian), Basque-Cantabrian Basin, northern Spain. The specific body morphology of representatives of the genus Helius preserved in Spanish amber was discussed in relation to the environmental conditions of the Maestrazgo Basin and Basque-Cantabrian Basin in Cretaceous.
