Remnants of the inland sea at Hughenden in north-western Queensland, Australia. Here you can dig in the topsoil and find extinct squid fossils known as Belemnites. What is a dry flat land was recently a shallow sea.
Australian Dinosaurs in recent past
Richmond and Hughenden, Queensland, Australian inland sea has left aquatic and land dwelling dinosaur fossils on the surface layers. The most complete Plesiosaur in the world is on display in the Richmond Museum. I personally have discovered turtle fossils in a nearby quarry.
