Occurrence Otoscaphites and Pteroscaphites occur mainly in the Turonian and Coniacian, but according to Wiedmann (1965: 449, text-fig. 16) may occur as late as the Campanian, and probably arose in the Upper Albian. The co-occurrence with P. kaffrarium suggests a Lower Coniacian date for this species. (By E. G. Kauffman) Family Inoceramidae Giebel, 1852 Inoceramid bivalves have long been used in regional biostratigraphy because of their abundance, wide fades distribution, and common co-occurrence with ammonites in Cretaceous strata. More recently, Inoceramidae have evolved an important role in global and intercontinental correlation, and are now a mainstay of wide-ranging Cretaceous biostratigraphic systems. Where a detailed radiometric scale is available, as in the Western Interior Cretaceous of.
