Stratigraphy of Tithonian (Ohauan‐Puaroan ) marine beds near Port Waikato, New Zealand, and a redescription ofBelemnopsis aucklandica(Hochstetter)

Palaeobiological and morphological aspects of JurassicOnychites(cephalopod hooks) and new records from the New Zealand Jurassic

“…Stevens 1965;Challinor 2001Challinor , 2003Challinor & Hudson 2007). Since they are resistant to sedimentary processes, belemnite rostra normally tend to occur as discrete fossils and are not associated with other belemnite body parts.…”

Synonymy and stratigraphic ranges ofBelemnopsisinthe Heterian and Ohauan Stages (Callovian‐Tithonian), southwest Auckland, New Zealand

“…Belemnopsis annae first appears in the Oraka Formation where, according to Stevens (1965), it is associated with Conodicoelites spp. Small specimens, apparently B. annae, were found during collecting for this work at locality R15/ f351, in the upper Oraka Formation (in beds d4 of Fleming (Challinor 1974(Challinor , 2001, has been sighted only at Okahu Stream in the western part of the map, and is mapped to the south by projection along the strike. The Upper Ohauan fossil Belemnopsis trechmanni occurs at f6984 and f7000 (Challinor 2001).…”

“…Age: Late Ohauan (Kimmeridgian/Tithonian). This zone is discussed fully in Meesook & Grant-Mackie (1995) and Challinor (1996Challinor ( , 2001.…”

Waipa Supergroup, New Zealand: A proposal

“…The base of the Waipa Supergroup is within the New Zealand Ohauan stage, a little below the range of the Puaroan fossil B. a. aucklandica (Meesook & Grant-Mackie 1995;Challinor 2001). This is approximately Late Kimmeridgian or c. 152 Ma on the international timescale of Gradstein et al (1995).…”
