“…Additionally, palm subfamilies including Coryphoideae, have their centres of distribution and diversification in the tropics ( Svenning et al., 2008 ; Reichgelt et al., 2018 ). Thus, the discovery of present and previously reported coryphoid palm megafossils of different organs, namely, leaves ( Srivastava et al., 2014 ; Roy et al., 2021 ), petioles ( Trivedi and Verma, 1981 ), leaf bases ( Bonde et al., 2000 ), stems ( Mahabale, 1958 ; Lakhanpal et al., 1979 ; Ambwani, 1983 ; Ambwani and Mehrotra, 1989 ; Gayakwad and Patil, 1989 ; Bonde et al., 2008 ; Khan et al., 2020a ) and fruits ( Bande et al., 1982 ) is generally taken to indicate a warm and humid tropical climate prevailed across what is now Madhya Pradesh, central India, during Late Cretaceous-early Paleocene times. This suggested paleoclimatic condition is also supported by earlier published qualitative paleoclimatic reconstruction using nearest living relatives (NLR) analysis ( Srivastava, 2010 ; Prasad et al., 2013 ; Srivastava and Srivastava, 2014 ; Manchester et al., 2016 ; Baas et al., 2017 ; Kapgate et al., 2017 ; Khan et al., 2019 ; Smith et al., 2021 ) and quantitative paleoclimatic data using Climate Leaf Analysis Multivariate Program (CLAMP) analysis ( Bhatia et al., 2021 ).…”

“…The earliest macrofossil records of the buckthorn family are woods from the latest Maastrichtian (Upper Cretaceous) to earliest Danian (early Paleocene) sediments ( ca. 66–65 Ma old) of the Deccan Intertrappean Beds of Madhya Pradesh, Central India (Chitaley et al, 1970; Upadhye & Patil, 1979; Trivedi & Srivastava, 1982; Gayakwad & Patil, 1993). The Upper Cretaceous (Maastrichtian) fossils provided compelling evidence for a Gondwanan presence of Rhamnaceae in insular India when the bulk of the subcontinent was still in the Southern Hemisphere.…”

Fossil leaves, fruits, and woods assigned to Rhamnaceae have been recorded from India, however, there are no previous reports of rhamnaceous fossil flowers from India. Here, we report the first fossil flowers in appreciable numbers from the early Eocene (Palana Formation) sedimentary sequences of Gurha Lignite Mine, Rajasthan, western India, and show that they are attributable to Rhamnaceae. We examined variation in flower morphology among extant and extinct rhamnaceous species as a basis for interpreting our fossil flowers. The specimens are small star‐like, pentamerous, actinomorphic, gamosepalous flowers with triangular, keeled sepals with acute apices, spathulate, short‐clawed petals alternating with sepals, shallow, five‐lobed nectary disc with prominent pentagonal outer margin, and a centrally placed globose ovary with stigma scar. The flowers co‐occur with ziziphoid leaves and are recognized as a new species Eopaliura indica Patel, Rana & Khan sp. nov. Because of aforesaid characteristics, fossil flowers are easily identifiable as Rhamnaceae and should provide a reliable means of documenting the evolutionary history of this family during the Cenozoic.

The megafossil records of monocotyledons assigned to Upper Cretaceous (Maastrichtian) onward from India have been reviewed along with their possible resemblances with the extant members to have a meaningful taxonomic and phylogenetic relationship. The early record of angiosperm megafossils assigned to the dicotyledons is from the Lower Cretaceous horizon of Rajmahal Hills, Bihar (now Jharkhand). A thorough search for the monocotyledons is yet to be made from these beds. The Deccan Intertrappean beds which belong to Maastrichtian (Upper Cretaceous) - Palaeocene age, are very rich in angiosperms comprising both dicotyledons and monocotyledons preserved especially in the form of permineralizations. The later epochs or series, however, are rich in compressions and impressions. The monocotyledonous flora is dominated mainly by palms (Family-Arecaceae) followed by the families of Scitamineae, Poaceae, Cyperaceae and Araceae. In order to understand the early monocotyledonous diversification future work is to be concentrated in the Rajmahal Intertrappeans and contemporary horizons belonging to the Lower Cretaceous Period. Thorough search for entire herbaceous elements, woody juvenile and arborescent members (palms, pandans, aroids, liliales, grasses, Cyperaceae, etc.), reconstructions of entire plants based upon organic occurrences and associations in addition to the isolated reproductive and vegetative organs of taxonomic significance is to be given priority. In depth knowledge of morphology and anatomy of comparable extant flora is required for their phylogenetic assessments.
