Where are the best dinosaur fossil collections in Australia?
Two prominent ones I am aware of are:
Australian Age of Dinosaurs Natural History Museum at Winton
Hosts a number of fairly complete large Australian dinosaur fossils. Also organises digs for tourists and school groups.
Australian Fossil and mineral museum at Bathurst.
Has a wide variety of fossil specimens (not just dinosaurs) including a T-Rex.
Any other good ones?
