Fossiliferous Triassic beds are exposed at intervals, from Kawhia 

 on the western coast of the North Island to Nugget Point on the 

 south-eastern coast of the South Island, a distance of 620 miles 

 or nearly 9° along the meridian. The most important localities 

 are briefly described in the following order : —

Moonlight Range. Carnic, Noric. 



The localities in the South Island are probably connected along 

 the structural axis by others where the fossils are still undiscovered, 

 or have been more or less obliterated through metamorphism. 



North Island. 

 Kawhia. 



The Jurassic strata are well exposed round the shores of Kawhia 

 Harbour, where they lie uneonformably beneath a horizontal cover 

 of Tertiary limestones, and Kawhia is the most important locality 

 in the North Island for Jurassic fossils. Outside the harbour in 



the Nelson district. At Mount Potts and Mount St. Mary the Triassic beds 

 form part of the eastern fringe of the complex of the Alpine Range, and are 

 crushed and partly metamorphosed. Except immediately south-west of 

 Kawhia Harbour, and on the southern and western side of the Hokonui 

 Hills, the Triassic beds stand everywhere practically vertical. 



At Kawhia, and in the far south, the Trias is succeeded conformably by 

 Jurassic rocks. At Nelson and in the Alpine Region no Jurassic is known. 

 In the Nelson district fossiliferous Trias, from the Ladino-Carnic to the Noric 

 inclusive, occurs. The Triassic limestones at Okuku are of uncertain 

 age, but probably Carnic. At Mount Potts and Mount St. Mary the 

 Ladino-Carnic (Kaihiku) and possibly Lower Carnic occur. In the ranges 

 extending from the Hokonui Hills to Nugget Point all divisions, from the 

 Kaihiku to the Rhfetic inclusive, are fossiliferous, and the overlying Jurassic 

 is also highly fossiliferous.
