Depleted olivine basalts are associated with radiolarian cherts while most pelagic limestones and cherts are found interbedded with alkali basalts. Similarly, for the pelagic realm, vertical partitioning of animals with depth will lead to the segregation of parasites among fish hosts. With continuing subduction the pelagic sediments might have been dragged beneath the accretionary prism leading to compaction and expulsion of large amounts of pore fluids. Many marine fishes have a larval stage in the pelagic zone before changing habitat to a more bottom dwelling life. Many marine fishes have long larval phase in the upper pelagic zone before transformation into a juvenile and a benthic life style. Like living pelagic animals they had preferences for particular water temperatures; different types of ammonoids were found in high or low latitudes. The pilot whale, harbor porpoise, and bottlenosed dolphin are all pelagic animals, which forage at a variety of depths. Ichnofossils and ichnofabrics in rhythmically bedded pelagic/hemi-pelagic carbonates: recognition and evaluation of benthic redox and scour cycles. Geochemistry of pelagic and hemipelagic carbonates: criteria for identifying systems tracts and sea-level change. A final point that may be made against the anoxiaextinction hypothesis is the detailed timing of the extinctions, particularly of pelagic taxa. The entire sequence represents a shallowing-up cycle with goniatites and myriad pelagic styliolinids in the lower, and neritic tentaculitids and brachiopods in the upper unit. The basalt-chert-pelagic limestone association (3) comprises oceanic basalts of supra-subduction zone-type chemical affinities, associated with siliceous (radiolarian) and calcareous pelagic sediments. With time, the sedimentary environment evolved and pelagic carbonate sediments were deposited either as interpillow voids and/or interbedded with the radiolarian cherts. All living lampridiforms are coastal or pelagic in temperate and tropical seas. See all examples of pelagic These examples are from corpora and from sources on the web.
