First direct dates of dingo bones from a site in Western Australia. Dingoes are one of the few mammals that crossed water (most likely accompanying humans) before European arrival. The dates and location of the site suggest that dingoes spread throughout the continent relatively quickly after their introduction.
New dates on dingo bones from Madura Cave provide oldest firm evidence for arrival of the species in Australia
Balme et al.
The dingo is the only placental land mammal aside from murids and bats to have made the water crossings to reach Australia prior to European arrival. It is thought that they arrived as a commensal animal with people, some time in the mid Holocene. However, the timing of their arrival is still a subject of major debate with published age estimates varying widely. This is largely because the age estimates for dingo arrival are based on archaeological deposit dates and genetic divergence estimates, rather than on the dingo bones themselves. Currently, estimates vary from between 5000–4000 years ago, for finds from archaeological contexts, and as much as 18,000 based on DNA age estimates. The timing of dingo arrival is important as post arrival they transformed Indigenous societies across mainland Australia and have been implicated in the extinction of a number of animals including the Tasmanian tiger. Here we present the results of direct dating of dingo bones from their oldest known archaeological context, Madura Cave on the Nullarbor Plain. These dates demonstrate that dingoes were in southern Australia by between 3348 and 3081 years ago. We suggest that following their introduction the dingo may have spread extremely rapidly throughout mainland Australia.

Homo floresiensis thrived on the island of Flores for thousands of years—and then vanished. One researcher is studying rat remains to figure out why.

We report on tetrapod (Reptilia, Amphibia, Mammalia, Aves) vertebrates recovered during excavations at Tron Bon Lei rockshelter on the south coast of Alor Island, eastern Indonesia. These include both archaeological specimens recovered from a 1 m² test pit dating from ∼21 kya cal BP to the late Holocene, and a modern eastern barn owl deposit recovered nearby. To discern between the depositional processes that accumulated the small numbers of micro- and macrovertebrate remains from the archaeological deposits, the taphonomic signature of the natural assemblage was quantified and compared to the archaeological record. The taphonomic data indicates that the tetrapod archaeofaunal remains are a combination of barn owl predation of microfauna and human predation of larger fauna. This approach provides new information on human-tetrapod interactions on Alor in Wallacea during the late Quaternary, including an apparent increase in cave site use and hunting intensity during the Pleistocene-Holocene transition, sea turtle butchery and probable transport, and extinctions of previously unknown giant to large rat species.

Very pleased to see my former colleagues at the ANU featured in this news – the discovery of the largest rat fossils ever, from East Timor.

The largest to have existed – giant rat fossils

Dog-Size Rats Once Lived Alongside Humans
LiveScience, 06 November 2015
Archaeologists with The Australian National University (ANU) have discovered fossils of seven giant rat species on East Timor, with the largest up to 10 times the size of modern rats.
Dr Julien Louys of the ANU School of Culture, History and Language, who is helping lead the project said these are the largest known rats to have ever existed.
“They are what you would call mega-fauna. The biggest one is about five kilos, the size of a small dog,” Dr Louys said.
“Just to put that in perspective, a large modern rat would be about half a kilo.”
The work is part of the From Sunda to Sahul project which is looking at the earliest human movement through Southeast Asia. Researchers are now trying to work out exactly what caused the rats to die out.

Remember last year’s study about the Gallus gallus and how they proved the Polynesians crossed over into the Americas? A new study published this week seems to contradict that claim.

The second and last of the paper presentations went by today with an near-marathon run of five sessions. By the end of the day I was having a little trouble concentrating already – glad that tomorrow will see a change of pace as we head out for a tour of the archaeological site of Johor!
Today we heard two calls for collaboration; Paul Tacon announced his Eagleandowl network for research themes in human evolution, creativity and cultural heritage research in the Australasian region. And from Vietnam, archaeologist Vu The Long called for the setting up of a network for sharing zooarchaeological information. To back up his appeal, he gave the analogy of communal water pots that are placed outside homes in Myanmar – water is shared and given to anyone who wants a drink. In the same way, he called for a similar spirit in the sharing of information and collaboration.
No papers on rock art presented in this conference – although I learnt that some rock art sites in Sulawesi have been quarried to destuction, much to my dismay. On the brght side, after speaking to archaeologists from Thailand and Vietnam I’ve begun to hear about more sites in the region. There’s certainly a lot more out there that needs to be properly documented!
No Wednesday Rojak for today – back next week!
24 April 2007 (Jakarta Post) – The fossil of a prehistoric crocodile has been found in Sangiran, already famous for being the site of the discovery of Java Man.
Prehistoric crocodile fossil found in Sangiran
The fossil of a prehistoric crocodile has been found at the Sangiran site in Sragen, Central Java, by a local resident.
“The first bit (of the fossil) that I found was the teeth of its upper jaw,” Mulyono, 31, told reporters at the Sangiran Fossil Laboratory on Monday.
Mulyono explained that the finding was quite by chance, as he was digging an irrigation gutter in his rice field. “Suddenly, I found the fossil,” Mulyono said. The discovery was made Friday and the excavation was carried out the next day.
On Monday, a number of employees from the Sangiran laboratory were still busy cleaning the fossil, which has a diameter of 49 centimeters and a length of 95 centimeters.
Gunawan, one of the employees, said the fossil was believed to have come from the Middle Pleistocene era, about 1.6 million years ago. “This is still a preliminary estimation, taking into consideration the location of the discovery at a hilly area in Pucung village in Kalijambe district, which has been classified in the Kabuh formation or the Middle Pleistocene era,” he said.
So far there has been no formal statement on how scientists will calculate the age of the fossil. “This is still being studied by archeological experts from the Sangiran Museum,” Gunawan said.

11 Jan 2007 (Vietnam Net Bridge) – A farmer in Nghe An province unearthed the bones of a massive elephant – a megafaunal specimen that could possibly be a mammoth. Yes, I know. Strictly speaking, this might not be considered under archaeology because archaeology is the study of material culture (and not just digging up stuff and cataloguing what you find). But I thought to include it anyway to err on the side of caution.
Ancient elephant skeleton discovered in Nghe An
VietNamNet Bridge – A huge elephant skeleton estimated to date back thousands of years has just been discovered in Khe Dinh River by a local farmer, Pham Van Dong, in Hamlet 4, Hong Son village, Do Luong district, Nghe An Province.
Dong said that on December 14, 2006 while going to his rice paddy at around 1 oâ€™clock, he saw what he thought was an upright iron wood log sticking out of the river. Finding it unusual, he dug around the place, and to his amazement, amongst layers of mud were more huge animal bones.
Immediately, he called his friends and relatives to come and help him with the digging. After nearly 3 days they had dug up a nearly complete skeleton of 500 kg which is in the process of fossilisation.
The skeleton has been identified as belonging to a species of enormous elephant and is estimated to date back thousands of years ago, as there is evidence of fossilisation in some of the bones like vertebra and shoulder bones.
