Fossil Kangaroo Teeth Reveal Mosaic Of Pliocene Ecosystems In Queensland
Tooth enamel reveals diet, habitats of extinct marsupials in southeastern Queensland
The teeth of a kangaroo and other extinct marsupials reveal that southeastern Queensland 2.5-5-million-years ago was a mosaic of tropical forests, wetlands and grasslands and much less arid than previously thought. The chemical analysis of tooth enamel that suggests this diverse prehistoric habitat is published June 12 in the open access journal PLOS ONE by Shaena Montanari from the American Museum of Natural History and colleagues from other institutions.
Montanari adds, "It is vital for us to understand what types of environments Australian megafauna thrived in during the Pliocene. Obtaining detailed environmental records from this time can help us find the drivers of the subsequent extinctions of many of these large marsupials."
