“…Recent reports of diverse fossil records from the Cauvery Basin are remarkably improved the knowledge about vertebrate diversities and also added new important forms (Underwood et al, 2011;Verma et al, 2012a;Goswami et al, 2013;Prasad et al, 2013). In addition, the new data also allows direct comparisons with contemporaneous vertebrates known from other continents such as South America, Africa, Madagascar and Europe and thus leading to infer crucial palaeobiogeographic patterns, in the context of the latest available palaeocoastline reconstructions of the Gondwanan continents.…”

“…The interesting and biogeographically significant discovery of troodontid dinosaur (Fig. 3s-t) from the Kallamedu Formation by Goswami et al (2013) extends the record of troodontid dinosaurs from Laurasia to the Late Cretaceous of Gondwana, particularly in India.…”

“…Further, it raises several issues such as whether troodontids dispersed to India from Laurasia during the Late Cretaceous or whether the group had an unknown broader Gondwanan distribution. Goswami et al (2013) argued that since the oldest record of troodontids is coming from the Middle Jurassic of Laurasia, their presence in the Late Cretaceous of India would have been a result of vicariance or dispersal associated with the movement of the tectonic plates.…”

“…These vertebrate faunas comprise frogs, lizards, snakes, crocodiles, turtles, dinosaurs and mammals and have received extensive attention as far as the evolution and biogeography of the Late Cretaceous vertebrates of India are concerned (Khosla and Verma, 2014 and references therein). Despite the fact that Cretaceous deposits of the Cauvery Basin, south India have been known to yield vertebrate remains since 1845, its vertebrate fauna only received significant attention recently (Underwood et al, 2011;Verma et al, 2012a;Goswami et al, 2013;Prasad et al, 2013). This communication is intended to review the Cretaceous vertebrate diversity of the Cauvery Basin and to provide an account of its biostratigraphic, Fig.…”

Charophytes from the Cretaceous–Palaeogene transition in the Jhilmili intertrappean beds of Central India

et al. 2022

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.

We report a new occurrence of the phyllodontid teleost fish Egertonia from the Late Cretaceous Kallamedu Formation of the Cauvery Basin, South India. This is the oldest occurrence of Phyllodontidae in India, and only the second Cretaceous Gondwanan occurrence of this genus, following a toothplate previously described from the Late Cretaceous Maevarano Formation, Madagascar. The presence of phyllodontid fish supports a fluvial-deltaic or brackish environment for the lower part of the Kallamedu Formation, a rich deposit including typically Gondwanan taxa, such as simosuchid crocodiles, bothremydid turtles and abelisaurid dinosaurs, as well as an anomalous troodontid dinosaur. Egertonia adds another taxon of primarily Laurasian distribution to the Kallamedu fauna and further expands the list of taxa known from the Late Cretaceous of both India and Madagascar, strengthening the degree of faunal similarity between the two landmasses in the latest Cretaceous.
