The first dinosaurs may have originated in the Northern Hemisphere, possibly in an area that is now Britain.

This is one of the conclusions of the first detailed re-evaluation of the relationships between dinosaurs for 130 years.

It shows that the current theory of how dinosaurs evolved and where they came from may well be wrong.

This major shake-up of dinosaur theory is published in this weeks’s edition of the journal Nature.

The reassessment shows that the meat eating beasts, such as Tyrannosaurus rex and Velociraptor, have been wrongly classified in the dinosaur family tree.

One of the implications is that dinosaurs first emerged 15 million years earlier than previously believed.

And the fossil evidence suggests that this origin may have occurred further north than current thinking suggests – possibly in an area that is now the UK, according to the new study’s lead author, Matthew Baron of Cambridge University.

Well, that was my first thought when I read the headline.
