Rounded toothed pearl-shell mounds at Elizabeth River near Darwin, Northern Territory
As the most visible remains of past coastal economies across the coast of northern Australia, mounds of shell dominated by roughback cockles (Tegillarca granosa) have featured often in explanations for Late Holocene Indigenous subsistence strategies. Recently more detailed local and regional studies continue to build a picture of some variations to this dominance, which demonstrate the breadth of marine species exploited, the extensive ecological…
Late Holocene coastal land-use, site formation and site survival
This paper introduces primary data on site contents, chronology and stratigraphy for four subsurface middens, which formed through the late Holocene on the Dampier Peninsula. Data from one surface midden collection are also presented. In this monsoonal coastal locality, variations in dune stability and sand flux are critical to archaeological site formation and preservation. Site specific factors determining sand sequestration into topsoils inter…
Human responses to the late Holocene freshwater transition on the northern coastal plains of the Alligator Rivers region in western Arnhem Land
Little is known about cultural change on the inlets of the northern subcoastal plains of the Alligator Rivers region during the transition period between sea-level highstand c.8,000 BP and the establishment of freshwater wetlands (c.2,000 BP to present). The research presented here begins to fill this gap by illustrating differences in Indigenous land-use at two sites only a few kilometres apart and both dating to c.1,000 years ago. Located on th…
Late Holocene Climate Change And Human Behavioural Variability In The Coastal Wet-Dry Tropics Of Northern Australia
Previously it has been argued that midden analysis from three geographically distinct coastal regions of tropical northern Australia (Hope Inlet, Blyth River, Blue Mud Bay) demonstrates that changes through time in Aboriginal mollusc exploitation reflect broader coastal environmental transformations associated with late Holocene climatic variability (Bourke et al. 2007). It was suggested that, while a direct link between environmental change and …
Description of Four New Species of Limestone-associated Torresitrachia Land Snails (Mollusca
Four new species of land snails of the genus Torresitrachia (Pulmonata: Camaenidae) are described from the Northern Territory of Australia: T. danvini, T. wallacei, T. cuttacutta, T. alenae.The species are distinguished on the basis of differences in shell and animal morphology, and 16S DNA analysis.All four species occur in the Katherine District (Daly Basin Bioregion), and have remarkably small geographical ranges and fragmented populations.Tho…
Anadara granosa' (Mollusca
In August 2008, sampling of mudflats on the southern shoreline of Middle Arm, Darwin Harbour, located an extant population of Anadara granosa (Linne), a bivalve mollusc commonly called Roughback Cockle [the FAO name is Granular Ark]. This species occurs in huge quantities in prehistoric shell middens around Darwin, but is now very rare and was thought to be possibly locally extinct
Godiva Quadricolor (Barnard, 1927) (Nudibranchia
The aeolid nudibranch Godiva quadricolor (Barnard, 1927), previously recorded as introduced into southern Western Australia (i.e., the Fremantle-Cockbum Sound area) and now probably naturalised there, is herein recorded lrom southern Queensland (i.e., Pumicestone Passage, immediately north of the Port of Brisbane), where a breeding population is presently established.The most likely source of both introductions is shipping.Godiva quadricolor orig…
Description of a new bathyal species of Calliostoma (Mollusca
Calliostoma bellutrix n. sp. is described from depths of 250 to 400 metres depth in the seaway between northern Australia and the southern Indonesian archipelago, and extending into the eastern Indian Ocean.Its smooth shell, with flat sides to the whorls and an acutely angled periphery ornamented with a "double" nodulose keel, render it unique among Indo-Pacific calliostomes, and it may be the sister species to C. scliroederi Clench and Aguayo fr…
New Data on Chelidonura Amoena Bergh, 1905 (Opisthobranchia
Chelidonura amoena Bergh, 1905 is redescribed, principally on material from Australia.The single extant type specimen is designated as lectotype.Considerable intraspecific colour variation is evident, with that relating to the caudal lobes being greatest.The variation in coloration and shape observed in one specimen from Belau lies outside those described for C. amoena and we believe it could be explained as the product of hybridisation with C. e…

Human responses to the late Holocene freshwater transition on the northern coastal plains of the Alligator Rivers region in western Arnhem Land
Little is known about cultural change on the inlets of the northern subcoastal plains of the Alligator Rivers region during the transition period between sea-level highstand c.8,000 BP and the establishment of freshwater wetlands (c.2,000 BP to present). The research presented here begins to fill this gap by illustrating differences in Indigenous land-use at two sites only a few kilometres apart and both dating to c.1,000 years ago. Located on th…
