What is "alcoota"

The Alcoota Fossil Beds are an important paleontological site located on Alcoota Station in Central Australia, 200 km north-east of Alice Springs. It is notable for the occurrence of well-preserved, rare, Miocene vertebrate fossils, which provide evidence of the evolution of the Northern Territory’s fauna and climate. The Alcoota Fossil Beds are also significant as a research and teaching site for palaeontology students.

The Alcoota deposit is a series of intermittently interconnected lakes within a large basin. Evidence suggests that the concentration of fossils is due to a phenomenon called ‘waterhole-tethering’: During dry periods, animals concentrated in the intermediate area of the continually shrinking spring-fed lake, resulting in the death of many animals. The Alcoota and Bullock Creek fossil faunas provide evidence that aridification was in progress in northern Australia during the mid Miocene geological time period.
