Why did dinosaurs go extinct?
Around 75% of Earth's animals, including dinosaurs, suddenly died out at the same point in time. So how was this global mass extinction caused by a rock hurtling into the coast of Central America?

Paul explains, 'The asteroid hit at high velocity and effectively vaporised. It made a huge crater, so in the immediate area there was total devastation. A huge blast wave and heatwave went out and it threw vast amounts of material up into the atmosphere.

'It sent soot travelling all around the world. It didn't completely block out the Sun, but it reduced the amount of light that reached the Earth's surface. So it had an impact on plant growth.'

Like dominos, this trailed up the food chain, causing the ecosystem to collapse. The reduction in plant life had a huge impact on herbivores' ability to survive, which in turn meant that carnivores would also have suffered from having less food available.

Breeding seasons would have been shorter and conditions harsher. All living things would have been affected in some way, both on land and in the ocean.

'There is a lot of discussion over the actual kill mechanism and how long that period lasted. There are still a lot of unknowns. But it was a massive event affecting all life on Earth, from microorganisms all the way through to dinosaurs,' says Paul.

The casualty list is long. Among them, ammonites, some microscopic plankton, and large marine reptiles all died out.

But the loss made room for the beginnings of the modern world.

kshudragrah antariksh ke madhyam se bahut teji se yatra kar rahaa tha or jab yah prithvi se takaraata tha, to isane ek vishaal chhed banaaya jise ek gaddha kaha jaataa tha.sab kuch nasht ho gaya tha or bahut saare kaale powder jise sota kaha jaataa tha, hawa main or puure grah ke chaaron ore ud gaya.is kaale powder kaa itnaa hissaa tha ki suraj ko thodaa avaruddh kar diya gaya tha.yah paudhon ke liye prithvi par paryaapt rup se ujjwal nahin tha.

kyonki paudhe acchhee tarah se nahin bad sakate the, anya sabhi jivit praani bhi prabhavit the.keval paudhon ko khaane vaale jaanwaron ke paas jivit rahane ke liye paryaapt bhojan nahin tha.kyonki kai paudhe khaane vaale jaanavar nahin the, maance khaane vaale jaanwaron ke paas bhi paryaapt bhojan nahin tha.jameen or samudr main sabhi jivit praaniyon ke liye sthitiyaan adhik se adhik kathin hoti ja rahi thim.

kyonki yah bahut pehle hua tha, yah sab kuch jaananaa mushkil he, lekin ham yah sunishchit karne ke liye jaanate hai ki yah ek bahut badi ghatana thi or yah sabhi jeevon ko sabase nanha jivit praaniyon se prabhavit karata he jo dianasor ke liye sabhi tarah se hai.us dauraan marane vaale jaanwaron kii suchi bahut lambii he.lekin bhale hi yah kai chizon kaa ant tha, yah kai nai chizon kii shuruyaat bhi thi.
