Hello.

Last night I saw a show called TWO IN THE TOP END( if you want to learn more about it, then click the high-lighted words).

It's a really good show about two good mates, Tim Flannery and John Doyle, going around in the top end of Australia.
Last night they went to a town called Normanton (this link will tell you more about the town), and there was this great big, full-scale model of this Croc that was shot in 1957, and it was the size of a small car!
It was shot by a woman called Krys and that's what they called the croc.

They also went along a beach that had been turned to stone, and it looked like a normal beach!
When they got on their hands and knees, they got a big hunk of it out, and the sand turned out not to be sand, but millions of tiny crushed shells and normal shells.
The shells were cemented together by calcium from fresh water and sea water mixing with the sand.

They went to a place called Riversleigh and showed a fossil of a croc's skull that was in a rock. They said that the croc was thousands of years old and that it ate differently to salt water croc's today. The fossil croc would slice hunks of meat off it's prey instead of doing a death roll like they do today.
