Module 4- Ecosystem Dynamics ( Part 2)

Question	Answer
Type of evidence used to show changing environments	- Rock types and fossils present in the rocks - Palaeoclimates can be determined by comparing extinct species with closely related extant species and looking at fossils found at one site.
Palaeontological vs Geological evidence	Palaeontological: Evidence derived from past life (e.g. fossils, paintings, built structures, footprints, etc) Geological: Evidence derived from rocks, minerals, soils and other geological materials
Sites of Aboriginal rock paintings and/or rock engravings	- Rock engraving (petroglyphs) in the Burrup Peninsula and Karlamilyi National Park in Western Australia - Aboriginal rock art (gunbim) in Kakadu National Park in the Northern Territory, Wollemi National Park, NSW
Paintings	Paintings show hunted animals and cultural activities. Some show extinct megafauna and x-ray paintings ( Western Arnhem land ) of heart, skeleton, lungs and other organs of food animals.
Rock art #1	- Explains land formation through stories - Rainbow Serpent - Paintings were crossed referenced and compared and paintings to show similarities to a pipefish -Around 6000 years ago sea level rose around 150 metres due to climate change bringing the sea and the pipefish (related to seahorse) to the landlocked western Arnhem Land. The loss of land and hunting grounds led to battle
