no sign of an extinction event affecting the dinosaurs.

Whatever had killed the fish and caused the mass extinction in the oceans, it hadn't affected life on land.

That meant dinosaur evolution couldn't have been kick-started by a mass extinction. That theory was wrong.
也就是说恐龙的进化并非由大灭绝引爆,这种假设是错误的
It meant scientists would have to find something else,
这意味着科学家们必须找出其它原因
something equally connected to the break-up of the super-continent
超大陆的分裂还关系到另一事件
and powerful enough to have transformed the evolution of the dinosaurs,
它的强大作用也足以改变恐龙的进化历程
so they turned to another theory: climate change.
因此他们开始关注另一种观点:气候变化。
