crossmanensis is from a locality that was thought to be late Turanian but may be younger, probably not as young as Santonian
(as argued by Clarke et al., 2011), but just as likely Coniacian as late Turanian (Massoni et al., 2015).

Simpson (1954) recorded that the sediments of the Abakaliki-Benue Trough underwent a minor folding phase during the Cenomanian and a major one accompanied by igneous intrusions during the Santonian
. The folding has an NE-SW trend, plunging southeastwards and allowing the younger formations to overstep into the older beds.
Individuals of two species of Santonian
hippuritid rudists were chosen from collections belonging to Peter Skelton (Open University, Milton Keynes, UK).

The hydro-stratigraphic characteristics of terrains that appear in the rock mass are fairly well defined: limestone and dolostone belonging to the Coniacian, Santonian
and Campanian units which are highly permeable and are the main karstic aquifers of the region.
The primary target, Murombe, a Barremian Age turbidite fan system and a secondary target, the Baobab, a shallower Santonian
Age structure were both penetrated.
The petrophysical analysis of electric logs indicates the presence of hydrocarbons in non-commercial concentrations in multiple layers of sandstones distributed throughout a 1,300-foot interval of Santonian
to Turonian age sediments.
