Background: 科学家最新发现了两亿五千年前类似恐龙的动物足迹。这一发现将恐龙存活的年代提早了几百万年。

These earliest dinosaur¹-like animals were about the size of domestic cats. They would have weighed two or three pounds (1 to 1.5 kilos) and walked on four legs.

But what's really intrigued² scientists is that they date from two million years after the worst mass extinction³ event in the history of the planet.

It was a time when volcanic⁴ eruptions⁶, sudden global warming and a stagnation⁷ of the oceans wiped out more than 90% of all life on Earth.

Up until recently scientists thought that dinosaurs⁸ emerged 15 to 20 million years after this event. But the new footprints suggest that they arose directly as a result of the devastation⁹, filling a gaping¹⁰ ecological¹¹ void. Without the mass extinctions there would have been no dinosaurs.
