Journal: Historical Biology
Year: 2024

The Bathonian‒Callovian (Middle Jurassic) genus Macrocephalites Zittel is distributed worldwide, and several of its species are used for inter- and intrabasinal biostratigraphic correlations. Here, the earliest occurrence of genus Macrocephalites, using an integrated approach incorporating data from ammonites, calcareous nannofossils and magnetostratigraphy from the Kachchh Basin of western India is presented. The calcareous nannofossils were extracted from the Macrocephalites triangularis Spath
