The first dinosaurs could have originated within the hemisphere, presumably in a district that's currently United Kingdom.
This is one amongst the conclusions of the primary elaborate re-evaluation of the relationships between dinosaurs for a hundred thirty years.
It shows that this theory of however dinosaurs evolved and wherever they came from could be wrong.
This major shake-up of archosaurian reptile theory is revealed during this weeks's edition of the journal Nature.
The assessment shows that the meat feeding beasts, like tyrannosaurus and maniraptor, are incorrectly classified within the archosaurian reptile clan.
One of the implications is that dinosaurs 1st emerged fifteen million years sooner than antecedently believed.
And the fossil proof suggests that this origin could have occurred additional north than current thinking suggests - presumably in a district that's currently the united kingdom, consistent with the new study's lead author, Matthew Baron of Cambridge.
"The northern continents actually contend a far larger role in archosaurian reptile evolution than we tend to antecedently thought and dinosaurs could have originated within the UK," he told BBC News.
The previous version of the archosaurian reptile clan was developed a hundred thirty years past by Harry Govier Seeley, a man of science conjointly acting at Kings school, London.
