Reay, M.B. 1993 Lists of early cretaceous to early Miocene fossils of the middle Clarence Valley, Marlborough. Lower Hutt: Institute of Geological & Nuclear Sciences Institute of Geological & Nuclear Sciences science report 93/03 86 p.
Abstract: This report accompanies a geological 1:50 000 map of the middle Clarence valley, 30 km northwest of Kaikoura. The area has been a key one for New Zealand stratigraphic studies because of its largely complete, fossiliferous, lower Cretaceous to lower Miocene sedimentary sequences, and the presence of intercalated dateable igneous rocks. Important fossil groups from the Clarence valley include ammonites, belemnites, dinoflagellates, foraminifera, bivalves (both marine and nonmarine), palynomorphs, plant macrofossils, and radiolaria. Collections of macrofossils from the area were utilised for the establishment and refinement of New Zealand cretaceous series and stages. An important result from recent work on plant microfossils from the area is the establishment of an early Cretaceous age for the Torlesse supergroup.
