T Rex was born in the Irish Sea, say scientists (Sunday Times, UK):
A huge meteorite that hit the Irish Sea and left a crater the size of Surrey may have helped giant dinosaurs come to dominate the planet, scientists have claimed.
The researchers, who have analysed rock formations in the British Isles and France, believe the impact caused a tsunami that swamped large parts of Europe.
They argue the meteor strike 200m years ago and others like it may have led to changes in the Earth's climate that caused some species to die out and others to dominate.
..."There was a relatively sudden increase in the size of dinosaurs around the time we have dated this impact," said Michael Simms (homepage), curator of paleontology at the Ulster Museum in Belfast who led the research.

The paper the above is based on ("Uniquely extensive soft-sediment deformation in the Rhaetian of the UK: Evidence for earthquake or impact?") is 'in press' and will appear in Palaeogeography, Palaeoclimatology, Palaeoecology [paleogeography, paleoclimatology, paleoecology]
