SCRAPS FROM AN OWLS TABLE - PREDATOR ACTIVITY AS A SIGNIFICANT TAPHONOMIC PROCESS NEWLY RECOGNIZED FROM NEW-ZEALAND QUATERNARY DEPOSITS

A fossil bone deposit from a cliff flanking the Tiropahi River, Westla nd, South Island, New Zealand, was dated at 17,340 +/- 140 radiocarbon years BP. The taphonomy suggests that the deposit was accumulated by a predator. Site characteristics, prey size and bone damage patterns ( greenstick fractures and evidence of digestion) suggest the predator w as the extinct or near-extinct Laughing Owl Sceloglaux albifacies. The species assemblage represented by the fossils show that Sceloglaux wa s an opportunistic predator whose diet included birds, bats, frogs, sk inks, geckos, and fish. The dominant prey were nocturnal ground-freque nting birds, particularly shearwaters and prions. The preferred habita ts of the prey species and the deposit's age suggest that the river va lley near the fossil site was forested, with areas of shrubland and gr assland, during the coldest part of the Otiran Glaciation.
