Abstract
Abstract Putikian strata exposed at Rangitawa Stream, Palmerston North, New Zealand, include the Rangitawa Fossil Beds, containing Pecten bene-dictus marwicki (Finlay), and the overlying Rangitawa Pumice (c. 370 000 years B.P.). Palynofloras indicate that a warm, humid climate existed when the Rangitawa Fossil Beds were deposited in very shallow marine and estuarine environments. Beech-podocarp forest predominated in the coastal areas. Subsequently, a climatic deterioration occurred and Rangitawa Pumice fell when a cold, glacial climate had developed as indicated by palynofloras dominated by shrub and grassland taxa. Stratigraphic position, palynology, and the fission-track age of Rangitawa Pumice suggest that the Rangitawa Fossil Beds were deposited near the end of oxygen isotope stage 11, and Rangitawa Pumice fell near the beginning of oxygen isotope stage 10.
