The Cenomanian–Turonian boundary (90.4 Ma) represents a major period of worldwide environmental disturbance. The physical manifestations of this are: elevated atmospheric and oceanic temperatures; a significant sea-level transgression; and a period of widespread anoxia, leading to the formation of oceanic black shales, and the extinction of 26% of all genera. Elevated δ13C values and enrichment of trace elements in Cenomanian–Turonian boundary sediments, combined with a reduction in 87Sr/86Sr…
