The main taxonomically identified material from Lower Cretaceous beds includes several specimens found in layers of the Hauterivian of western Russia (Fischer et al., 2015; Fischer et al., 2017), of the Barremian
and Aptian of Colombia (Hampe, 1992; 2005; Paramo-Fonseca et al., 2016; Gomez-Perez and Noe, 2017); and of the Aptian and Albian of Australia (Longman, 1924; Kear, 2003).
The idea that Chloranthaceae were an important early angiosperm group dates back to Couper (1958), who described Clavatipollenites hughesii from the Barremian
of England and compared it with pollen of Ascarina lucida in New Zealand.
The Alam El Bueib Formation is subdivided into several members, including (1) the Matruh Member (Neocomian, lower Aptian) which is composed of shales and sandstones, (2) the Umbarka Member (Barremian
) which consists mainly of sandstone and shale with few streaks of limestone, and (3) the Mamura Carbonate Member which is mainly composed of limestone .
