THOSE terrible lizards who once ruled the Earth are back. A week of prehistoric fun and activities has been unleashed as part of APN Australian Regional Media's Dino Week.

From today, readers will be able to start collecting their own double-page dinosaur posters - from tyrannosaurus rex to brontosaurus - with a different one available in papers each day until Friday.

Dino lovers can also learn fun prehistoric facts then put their knowledge to the test with a free quiz available online at http://www.qt.com.au/dino from June 2-8.

Participants can choose from easy, medium or hard questions to see how much they know about dinosaurs.

To learn even more about these amazing beasts from the past, APN will host a live online chat with Queensland's own dinosaur expert, Dr Steve Salisbury.

Dr Salisbury is a senior lecturer at the University of Queensland and research associate of the Carnegie Museum of Natural History in the US.

His team's research focuses on the evolution of Australian dinosaurs and crocodilians, and the prehistoric world they inhabited.

Steve conducts regular expeditions to central-western Queensland, The Kimberley, New Zealand and Antarctica.

He will be fielding any prehistoric questions people have from Tuesday from 11am-noon.

To find out more and register to receive the reminder visit http://www.qt.com.au/dinosaurlivechat.

Also don't forget to keep collecting tokens in the paper with 40 unique dinosaur cards to hunt down.

All you have to do is redeem tokens from the paper, follow the big footprints into a participating newsagent and exchange it for a set of two cards.
