“…Fossiliferous strata belong to the Toupi Formation, which comprises mainly mudstone and shale. For the fossil-bearing sediments, pollen data indicate an age between 17 and 14 Ma (Figure 1B; Table 1; Sun and He, 1987;Ma et al, 2020;He and Wang, 2021). Most of this time interval belongs to the Miocene Climatic Optimum.…”

The study of Neogene palaeoclimate supports our understanding of effects and consequences of current climate changes. However, many aspects and details of Miocene climate development are still unclear. Fossil leaves are a valuable and rich source of palaeoclimate proxy data. In this contribution, two Miocene leaf assemblages from eastern China, the Toupi flora and the Shengxian flora, were studied with respect to palaeoclimate and leaf economics. Whereas the Shengxian flora is dated to the lower Tortonian, the Toupi flora dates to approximately the border between Burdigalian and Langhian. For palaeoclimate, Climate Leaf Analysis Multivariate Program (CLAMP) was applied. In addition, Leaf Mass per Area (LMA), an essential leaf trait strongly correlated to leaf longevity, was included and was calculated morphometrically. For both sites, the data indicated a principally warm and humid climate, with Mean Annual Temperature (MAT) values between 13 and 17 °C. Also, the LMA indicates evergreen vegetation for both sites, consistent with the identified fossils and palaeoclimate. For Shengxian, however, this study concludes there was a lower temperature in the cooler season. This might possibly indicate a stronger temperature seasonality for this site due to slight climate cooling and East Asian monsoon intensification from the middle to late Miocene.

“…The Miocene localities from where traces of plant-insect interaction have been reported include Toupi Formation, Fotan Group, and Bangmai Formation, China (Ma et al, 2020;Dong et al, 2018;Zhang et al, 2018;Wang et al, 2021), Gish Clay Formation (Khan et al, 2015) and Dafla Formation (Khan et al, 2014b) of India. The percentage of leaf damage was highest in the Gish Clay Formation, Darjeeling (38%) followed by the Dafla Formation, Arunachal Pradesh (35%), the Fotan Group, Zhangpu County, China (34.1%), the Bangmai Formation, Yunnan Province, China (21%) and the Toupi Formation, Guangchang, China (20.33%).…”

“…The occurrence of galls in angiosperms has a diverse and abundant fossil record [9][10][11][12][13][14] . Angiosperm radiation during the mid-Cretaceous hosted a major expansion of gall damage types in the early lineages of Austrobaileyales, Laurales, Chloranthales, and Eurosidae and a related increase in arthropod diversity 14 .…”

We report a new type of fossil margin galls arranged in a linear series on dicot leaf impressions from the latest Neogene (Pliocene) sediments of the Chotanagpur Plateau, Jharkhand, eastern India. We collected ca. 1500 impression and compression leaf fossils, of which 1080 samples bear arthropod damage referable to 37 different damage types (DT) in the ‘GuidetoInsect(andOther)DamageTypesinCompressedPlantFossils’. A few leaf samples identified as Ipomoea L. (Convolvulaceae) have specific margin galls that do not match any galling DT previously described. This type of galling is characterized by small, linearly arranged, irregular, sessile, sub-globose, solitary, indehiscent, solid pouch-galls with irregular ostioles. The probable damage inducers of the present galling of the foliar margin might be members of Eriophyidae (Acari). The new type of gall suggests that marginal gall-inducing mites on leaves of Ipomoea did not change their host preference at the genus level since the Pliocene. The development of marginal leaf galling in Ipomoea is linked to extrafloral nectaries that do not offer protection against arthropod galling but indirectly protect the plant against herbivory from large mammals.
