Ichthyoliths from Some Southeast Atlantic Sediments, DSDP Leg 40

Ichthyoliths from Site 436, Northwest Pacific, Leg 56, Deep Sea Drilling Project

“…Table 2 lists, by numerically ordered name-descriptions, the ichthyolith subtypes identified at Site 436. The description of two new ichthyoliths requires the following changes to the system of descriptors ( Doyle et al, 1974;Dunsworth et al , 1975;Ramsey et al, 1976; Triangle smooth surface Doyle et al, 1978) …”

Ichthyolith Evidence for the Age of Reflector Au, Deep Sea Drilling Project Site 603

“…Since then a new subject, "stratignathy," has been developed by Riedel, Doyle, and their coworkers (Doyle et al, , 1977(Doyle et al, , 1978Dunsworth et al, 1975;Doyle and Riedel, 1979, a, b, 1980, 1981Edgerton et al, 1977;Kaneps et al, 1981;Gottfried et al, 1984 a, b; and other papers currently in press). These publications have developed and refined an identification scheme for ichthyoliths.…”

Ichthyolith Biostratigraphy of Western North Pacific Pelagic Clays, Deep Sea Drilling Project Leg 86

“…INTERPRETATIONS Over the past 10 yr., we have built up an ichthyolith stratigraphy by establishing the ranges of approximately 120 taxa (subtypes) in sediment sequences in which ages have been determined on the basis of other groups of microfossils, mainly calcareous nannoplankton (Doyle et al, 1974;Dunsworth et al, 1975;Doyle et al, 1977;Gottfried et al, 1985). Application of this ichthyolith stratigraphy to pelagic clay sequences results in age assignments to about the level of epochs within the Cenozoic (Edgerton et al, 1977;Doyle and Riedel, 1979b;Kaneps et al, 1981).…”
