“…Aucellina euglypha and Dimitobellls superstes are less common. Ammonites (Henderson 1973), foraminifera, dinoflagellates, pollen, and fossil plants have been recorded, and a megastrobilus (Mildenhall & Johnston 1971) and Ichthyosaur (Fleming et al 1971) of Motuan age described. MODE OF DEPOSITION Widespread parallel-and croSslamination and frequent ripple-marking, together with fine grain-size and common plant remains, indicate that traction currents played a major role in deposition.…”

“…Hector (1874) described a vertebral centrum from Triassic beds at Mt Potts, Canterbury, and erected the taxon Ichthyosaurus australis (later re-named Ichthyosaurus pottsi Hector, 1886 and Ichthyosaurus hectori Lydekker, 1889) on the basis of this same specimen. Strata at Mt Potts later yielded further remains, mainly vertebrae (for an historical overview see Fleming et al 1971), but this taxon remains indeterminable. Other Triassic ichthyosaur material, including a well-preserved rostrum fragment with teeth, was reported by Campbell (1965) from Otamita Stream, Southland.…”

“…Other Triassic ichthyosaur material, including a well-preserved rostrum fragment with teeth, was reported by Campbell (1965) from Otamita Stream, Southland. Three North Island Lower Cretaceous ichthyosaur specimens (consisting of vertebral centra) were described by Fleming et al ( 1971 ) from Gentle Annie, Mangapurupuru, and Whakarora Streams, all in the Tinui district, eastern Wellington.…”

An ichthyosaur fragment from the Cretaceous of Northland, New Zealand

The rostrum fragment of an ichthyosaur from Northland in New Zealand is described. The specimen appears to belong to the genus Platypterygius. It is the first Mesozoic marine vertebrate fossil reported from Northland and the first cranial element of a Cretaceous ichthyosaur from New Zealand. The fragment is, unfortunately, of uncertain provenance and could have come from the widespread Northland Allochthon (Early Cretaceous-Oligocene) or the allochthonous Houhora Complex (late Early Cretaceous) or Whatuwhiwhi Formation (latest Early to Late Cretaceous), perhaps by way of initial derivation from the Early Miocene Omapere Conglomerate.

“…The mode of occurrence and style of preservation of invertebrates encourages us to expect vertebrates and, indeed, more are known than is apparent from the small number of published reports (e.g., Campbell 1965;Fleming et al 1971;Fordyce 1990). We describe here one of the few Triassic vertebrates to be reported formally from New Zealand.…”
