A latest Paleocene charophyte flora collected from the South Gobi area in the Junggar Basin, western China, includes the geographically widespread taxa Peckichara torulosa var. varians (Dollfus and Fritel, 1919) Sanjuan, Vicente, and Eaton, 2020, Lychnothmanus vectensis (Groves, 1926) Soulié-Märsche, 1989, and Gyrogona lemani capitata Grambast and Grambast-Fessard, 1981. Lychnothmanus vectensis (as Lychnothmanus aff. L. vectensis) is known from the Cretaceous–Paleocene transition in eastern China and the latest Paleocene in western China, with likely additional records from the United States (Utah). The earliest European records of L. vectensis are from the late Eocene to early Oligocene in Spain, France, and England. Similarly, the oldest record of G. lemani capitata is from the latest Paleocene in the South Gobi area, with younger records from the middle Eocene of France. These latest Paleocene gyrogonite assemblages demonstrate the origin of these charophyte lineages in Asia. The dispersal of these charophytes from Asia to Europe in the middle to late Eocene appears to have occurred before the retreat of the Turgai Strait in both the Tarim area and the Siberian Basin by the end of the late Eocene and before the “Grande Coupure” in Europe and the Mongolian Remodelling in Asia during the Eocene–Oligocene transition. We hypothesize that waterbirds may have facilitated this intercontinental dispersal, and that idea is supported by the shared occurrence of avian groups in Central Asia and Europe in the middle and late Eocene.

The timing and ecological impacts of the Deccan Traps large igneous province eruption are vigorously debated. Pre–Cretaceous-Paleogene (KPg) boundary impacts of Deccan volcanism have been widely identified in marine sediments, but direct evidence of terrestrial impacts remains rare. We used mercury concentrations and isotopic compositions, a proxy for volcanic activity, to assess impacts on terrestrial environments. We studied two drill cores across the KPg boundary in eastern China that represent two different depositional environments: clastic deposits in the Jiaolai Basin and carbonate deposits in the Pingyi Basin. Both drill cores exhibit strong Hg enrichment prior to the KPg boundary. Near consistent mass-independent fractionation (MIF) of odd-Hg isotopes (odd-MIF) in the Jiaolai Basin likely indicates a volcanogenic source of Hg spikes below the KPg boundary. Odd-MIF isotopes in the Pingyi Basin likewise suggest a volcanogenic Hg source but with a terrestrial Hg signature of lower Δ199Hg values before and after the Hg spike interval. The Hg enrichment level can be stratigraphically correlated to the beginning of the Latest Maastrichtian warming event (LMWE) and is consistent with a strong, negative carbon-isotope excursion (CIE) in both δ13Corg (organic matter) and δ13Ccarb (carbonate), suggesting a disturbance of the global carbon cycle induced by a major pulse of Deccan Traps volcanism. Our discovery of a terrestrial record of pre-KPg boundary Deccan volcanism provides robust evidence of global influence of the Deccan Traps large igneous province during the LMWE.

“…During the last four decades, the study of Upper Cretaceous charophytes has been considered by many workers to be an important biostratigraphic tool for delineating the Cretaceous–Palaeogene (K–Pg) boundary throughout the world, notably in North and South Americas (Jaillard et al, 1993; Peck & Forester, 1979), Europe (Feist, Grambast‐Fessard, et al, 2005; Feist, Liu, & Tafforeau, 2005; Vicente, Expósito, et al, 2016; Vicente, Villalba‐Breva, et al, 2016; Villalba‐Breva & Martín‐Closas, 2013), and Asia (Karczewska & Ziembińska‐Tworzydlo, 1983; A. Khosla, 2014; Li, Wang, Zhang, Wan, & Martín‐Closas, 2019; Tian et al, 2021). In contrast, the record of Indian Late Cretaceous charophytes is poorly documented, having been recovered primarily from the infra‐ and intertrappean beds of the Deccan Volcanic Province (DVP) of peninsular India (A. Khosla, 2014; Srinivasan, Bajpai, & Sahni, 1994; Srinivasan, Sahni, & Bajpai, 1992).…”

Charophytes from theCretaceous–Palaeogenetransition in the Jhilmili intertrappean beds of Central India

The Jhilmili intertrappean beds (Chhindwara District, Madhya Pradesh) of Central India are studied from a palaeoenvironmental, palaeoecological, and palaeobiogeographical perspective using fossil charophytes. These beds have yielded a diverse charophyte assemblage, consisting of Platychara perlata, Platychara raoi, Platychara sahnii, Peckichara cf. varians, Nemegtichara cf. grambasti, and Chara sp. 1. These charophytes were recovered from a 60 cm thick clayey and nodular limestone unit that is underlain by claystone and overlain by laminated claystones deposited on fluvial floodplains. This charophyte assemblage suggests a Late Cretaceous-Early Danian age, which agrees with the previous dating carried out using freshwater to brackish water ostracods and planktic foraminifera found in the same beds, together with dasycladalean and halimedacean chlorophytes. The Jhilmili intertrappean charophyte assemblage resembles those found in other infra-and intertrappean sections of western, central, and southern India. The charophyte assemblage indicates that during the Cretaceous-Palaeogene timespan the Indian subcontinent mainly experienced interchange with Laurasia (China, Europe, and North America) but also with Gondwana (North Africa and South America). In the opposite sense, Laurasian species might have dispersed to India by means of a sweepstakes route across the Kohistan-Dras volcanic arcs.
