more than 65 million years ago. by measuring how they changed over the years, researchers worked out how they are related, and how they evolved. but a new reassessment published in thejournal nature, which suggests that that theory which has lasted 130 years, maybe wrong. the current theory is that there are two main groups of dinosaurs. one, which includes the stegosaurus, and another, which has two branches. the vegetarians such as the brontosaurus, and the meat eaters, such as the savage tyrannosaurus rex. it turns out that the meat eaters are in the wrong group, and should be with the stegosaurus. it also shows that the very first dinosaurs did not originate in what is now east africa, but much further north, possibly in an area which is now britain. we've taken dinosaur origins, which originally were thought to be southern hemisphere, and brought them into the northern hemisphere, and it could well be that dinosaurs originated even

within britain itself. what we have here is a key specimen in this analysis. and here is the fossil that led to this shock finding — a primitive dinosaur the size of a cat was found in lossiemouth in scotland. it was an animal like this that led to the creatures that dominated this planet for 165 million years. the new family tree will mean that we will have to rethink our ideas of how they evolved and spread across the globe. this is a fairly major change to our knowledge of dinosaurs. we have had a system in place for 130 years, we thought we understood the relationships of these big groups of animals, but it may be that we have a major rearrangement of the dinosaur tree. this re—evaluation of fossils challenges a theory that has been accepted since the victorian era, and so will be controversial. but if it is proved to be correct, textbooks on the subject will have to be rewritten. let's take a look at the weather.
