Question

I need a timeline of both geological and biological events in the formation of Australia from Gondwana?

Answer 1

We know that the break-up of Gondwana started about 140 million years ago and Australia split from Antarctica at 96 million years ago. Australia is currently moving away from Antarctica at a speed of 6 cm per year, and is about 2,900 km away from Antarctica (1 km = 100,000 cm). How long would this much movement have taken? This result will NOT give you the accurate rate of movement, because Australia's motion has sped up and slowed down during its drift! The oldest sea-floor between Australia and Antarctica is about 96 million years old, so this is why we think they broke apart at this time.

Answer 2

um.....ragi...you could try using wiki

i'm having trouble myself. (or you could use http://www.scientificpsychic.com/etc/tim...

but there's not too much)

good luck....bio assignment is so hard

Answer 3

You can get the geological timeline from one of the websites below. You will then need to compare the fossil record before and after the time of breakup and look at how the organisms diverged.  It is not easy to find this but the links below are a start. You may need to go to published texts.
