Dinosaur Without Bones – the Footprint

In December 1980 at a place called Knowledge Creek in the Otway Ranges one footprint of a little plant-eating dinosaur was found.  It was found by two palaeontologists, Tom and Pat Rich, who worked for Museum Victoria and Monash University.  They and their volunteers had been prospecting for years along the rugged shores of Victoria, Australia in rocks that were constantly battered by the sea – and the little footprint was a real surprise.  Tom took out his hammer and chisel and hammered it out of the rocks, and then he and his wife Pat climbed back up the rugged cliff using a rope.  They decided to never again try to get to the site again, as it was just too difficult.  The little footprint was likely from one of the dinosaurs that was so common in this region more than 105 million years ago – maybe Leaellynasaura, Atlascopcosaurus or Qantassaurus

The bones and teeth of these little dinos have been found elsewhere along the Otway Coast (Dinosaur Cove for example) and in the Inverloch area to the East.  But this print was not bone or tooth, it was the impression left by a little dinosaur long, long ago – a dinosaur trace without bones!  

The impression of the footprint being above the surrounding rock is unusual.  Most often footprints of dinosaurs are preserved as depressions in the rocks in which they are found.  What happened in this case was that the dinosaur made such a depression.  Then the depression was subsequently filled with a red sand that was coarser than the grey-green sediment in which the impression was made.  

Thus, a natural cast of the footprint was made. When the pounding waves of the sea uncovered this footprint cast, because it was harder than the underlying sediment in which it had originally been made, it did not erode as fast.  Therefore, the cast stands above what remains of the softer sediment, now rock, that once enclosed it.

A mould of silicone rubber was made of the print and then Plaster of Paris poured into that mould.  That is what you have in your little Dino Bag.  You can now paint it and use some of the ground up rock which comes from where the print was made, and you will have something that looks just like the real thing – for your very own.
