Paleobotany Manchester, Steven [1], Ramteke, Deepak [2], Kapgate, Dashrath [3], Smith, Selena [4]. Angiosperm affinity of Surangea fruits from the late Cretaceous Deccan Intertrappean beds of central India. The genus Surangea Chitaley & Sheikh, based on permineralized specimens from the Late Maastrichtian Deccan intertrappean beds of central India, was originally considered to represent a fern megasporangium. Reexamination of original material plus new specimens has revealed that the structures are capsular fruits with well defined seeds, rather than megasporangia. We describe Surangea fruits in more detail, based on acetate peels and micro-CT scanning analyses and document its distribution among multiple localities of the Deccan intertrappean beds. The fruits are globose pentalocular capsules with numerous seeds per locule and axile placentation. The seeds are prominently ornamented with parallel ridges and have a curved embryo cavity and a prominent aril. Although the precise affinities of Surangea remain elusive, the fruit clearly represents a eudicot and is likely of rosid affinity. The recognition of eudicot affinities for Surangea adds to the diversity of angiosperms known from the flora that inhabited India several million years before the tectonic collision of this land mass with Eurasia.
