Dinosaur bones confirm similarities in different parts of the world

Australian dinosaur had UK double
By Jonathan Amos Science correspondent, BBC News

A 5cm-wide (2in) fossil may have something big to say about how dinosaurs ranged across the Earth.The 125-million-year-old neck vertebra belonged to a spinosaurid - an animal with a crocodile-like snout that it probably used to prey on fish.The specimen is the first such dinosaur identified in Australia but one that is nearly identical to a UK creature.This suggests northern and southern hemisphere dinos had a lot more in common than previously thought.The traditional idea has been that these ancient animals could be placed into distinctive, geographically separated, groups. This small vertebra undermines that view, says Dr Paul Barrett from London's Natural History Museum."After looking at this specimen and having been forced to re-assess the distribution of spinosaurids, we took a look at other dinosaur groups from Australia, including the Tyrannosaur our team announced last year," he told BBC News."Taking all this evidence into account, we started to realise that a lot of dinosaur groups we'd thought of as either northern specialists or southern specialists actually had more cosmopolitan distributions."It may be just one bone, but the team says it displays features that are unmistakably those of a spinosaurid.

If this is the case perhaps it helps towards the explanations for so many cryptids in different parts of the world being similar such as bigfoot and yeti, nessie and other lake creatures. I am not saying they are all dinosaurs  but taking into account  evolution , if these creatures are relics of another era , they would have possibly evolved in some similar ways, perhaps keeping the same basic shape. Just a midweek speculative thought for you
