A forewing of the Jurassic dragonfly Austroprotolindenia jurassica Beattie & Nel (Odonata: Anisoptera) from the Talbragar Fish Bed,New South Wales,Australia

Nel, A., Frese, M., McLean, G. & Beattie R., May 2017. A forewing of the Jurassic dragonfly Austroprotolindenia jurassica from the Talbragar Fish Bed, New South Wales, Australia. Alcheringa 41, 532–535. ISSN 0311-5518.

The discovery of a well-preserved dragonfly forewing in the Upper Jurassic Talbragar Fish Bed near Gulgong and attributed to Austroprotolindenia jurassica Beattie & Nel allows this taxon to be placed in Protolindeniidae. It extends the palaeogeographical distribution of this family, previously known only from the Jurassic of Europe, to Australia.

A 28,000 year old excavated painted rock from Nawarla Gabarnmang,northern Australia

We report new archaeological excavations from northern Australia revealing part of a charcoal design likely to be c. 28,000 years old (and chrono-stratigraphically constrained within the period 15,600–45,600 cal BP) on a small rock slab fallen from the ceiling at the rockshelter of Nawarla Gabarnmang in Jawoyn country, Arnhem Land. This represents the oldest confirmed pictograph in Australia.     

Retention of hunter–gatherer economies among maritime foragers from Caleta Vitor,northern Chile,during the late Holocene: evidence from stable carbon and nitrogen isotopic analysis of skeletal remains

On the basis of stable carbon and nitrogen isotope analysis of human remains, this paper provides evidence for the retention of hunter–gatherer economies among coastal inhabitants in northern Chile during the late Holocene – at the same time that inland populations were adopting agricultural economies. Coastal diets from the Caleta Vitor region of the Atacama Desert were dominated by marine-based foods, predominantly from upper trophic levels. The focus on reliable marine food resources is interpreted as a risk minimisation strategy in this marginal arid environment. Although these coastal hunter–gatherers adopted other goods and traditions from agricultural populations, their participation in this larger interregional exchange network did not affect their basic subsistence economies.     

High-resolution radiocarbon dating of marine materials in archaeological contexts: radiocarbon marine reservoir variability between Anadara, Gafrarium, Batissa, Polymesoda spp. and Echinoidea at Caution Bay, Southern Coastal Papua New Guinea

The remains of shellfish dominate many coastal archaeological sites in the Pacific and provide a wealth of information about economy, culture, environment and climate. Shells are therefore the logical sample type to develop local and regional radiocarbon chronologies. The calibration of radiocarbon (¹⁴C) dates on marine animals is not straightforward, however, requiring an understanding of habitat and dietary preferences as well as detailed knowledge of local ocean conditions. The most complex situations occur where terrestrial influences impinge on the marine environment resulting in both the enrichment and depletion of ¹⁴C (Ulm Geoarchaeology 17(4):319–348, 2002; Petchey and Clark Quat Geochronol 6:539–549, 2011). A sampling protocol that combines a high-resolution excavation methodology, selection of short-lived samples identified to species level, and a tri-isotope approach using ¹⁴C, δ¹³C and δ¹⁸O, has given us the ability to identify ¹⁴C source variation that would otherwise have been obscured. Here, we present new research that details high-resolution mapping of marine ¹⁴C reservoir variation between Gafrarium tumidum, Gafrarium pectinatum, Anadara granosa, Anadara antiquata, Batissa violacea, Polymesoda erosa and Echinoidea from the Bogi 1 archaeological site, Caution Bay, southern coastal Papua New Guinea. These isotopes highlight specific dietary, habitat and behavioural variations that are key to obtaining chronological information from shell radiocarbon determinations.
