摘要

在新南威尔士州中部北部Cuddie Springs的地平线上发现的牛顿Genyornis newtoni和新荷兰巨兽(Dromaius novaehollandae)的化石遗迹可以确定为距今3万年前。牛顿Genyornis newtoni和新荷兰巨兽d.novaehollandiae是在连续的地层中发现的，与人类居住的人工制品和其他巨型动物物种有关。古环境资料表明，金合欢标本的沉积时期为干旱植被群落，以藜足类灌木为主，分布有桉树和金合欢。Dromaius的出现和Genyornis的消失与当地转向草原和Cuddie Springs湖干涸的时间一致。在末次极大期之前的干旱区，提供了Genyornis持续存在的新证据。

Genyornis newtoni and Dromaius novaehollandiae at 30,000 b.p. in central northern New South Wales

Fossil remains of Genyornis newtoni and Dromaius novaehollandiae recovered from horizons at Cuddie Springs, in central northern New South Wales, are securely dated to greater than 30,000 b.p. Genyornis newtoni and D. novaehollandiae were found in sequential layers in association with artefacts of human occupation and other species of megafauna. Palaeoenvironmental information indicates the specimens of G. newtoni were deposited when the region supported an arid vegetation community, principally chenopod shrubland with scattered Eucalyptus and Acacia species. The appearance of Dromaius and disappearance of Genyornis coincided with a local shift to grasslands and the drying of the Cuddie Springs lake. New evidence is presented for the persistence of Genyornis in the arid zone during the lead up to the Last Glacial Maximum.

期刊介绍： Alcheringa : An Australasian Journal of Palaeontology is the official journal of the Australasian Palaeontologists. Alcheringa covers all aspects of palaeontology and its ramifications into the earth and biological sciences, including: Taxonomy- Biostratigraphy- Micropalaeontology- Vertebrate palaeontology- Palaeobotany- Palynology- Palaeobiology- Palaeoanatomy- Palaeoecology- Biostratinomy- Biogeography- Chronobiology- Biogeochemistry- Palichnology. Review articles are welcome, and may be solicited from time to time. Thematic issues are also possible. Emphasis is placed on high quality and informative illustration, in both line drawings and photographs. Papers of general significance may receive preference over those of more local interest.
