Festive Road is unusually busy today. The main road is being repaired and all the morning traffic crawls and honks its way past my door. So I decide to go to the costume shop, in search of an adventure and some peace and quiet. Once in the shop, I find a caveman’s costume and decide there can’t be much traffic in those days. So I head off to a land far away from the rush hour traffic of Festive Road… or so I thought.
The dinosaurs were already in decline 50 million years before the asteroid strike that finally wiped them out, a new study suggests. The assessment adds further fuel to a debate on how dinosaurs were doing when a 10km-wide space rock slammed into Earth 66 million years ago. A team suggests the creatures were in long-term decline because they could not cope with the ways Earth was changing. Researchers analysed the fossil remains of dinosaurs from the point they emerged 231 million years ago up to the point they went extinct. To begin with, new species evolved at an explosive rate. But things started to slow about 160 million years ago, leading to a decline in the number of species which commences at about 120 million years ago.
