Abstract

A well-stratified succession of fossiliferous sediments occurs in Tight Entrance Cave, southwestern Australia. These infill deposits contain the remains of megafauna and have accumulated intermittently since the Middle Pleistocene: >137,137-119 and 50-29 ka, according to the results of C-14, U-Th, ESR and OSL dating techniques. Megafaunal species richness was highest in the latest part of the penultimate glacial maximum and during the subsequent last interglacial (137-119 ka), but remains are less abundant following an apparent similar to 70 ka depositional hiatus in the sequence. Most megafaunal specimens from the upper (
