What killed the dinosaurs

[Erdinger]

A dramatic change in the climate culminating in the 'Ice Age', principally. Not very SPORTING.

There are a range of 'conspiracy' theories which vary - climate change is the most popular, but meteors from space are included, as are a sudden 'plague' and various other notions. I'm more intrigued by the accepted notions that they were all a slate grey colour, roared and moved slowly, when for all we know, they could have been furry, battenburg coloured, run like greyhounds and squeaked like mice! Who knows?

A huge meteor impact is a very likely situation, if it imapcted the sea it would create a huge tsunami, along with that would put so much dust and debris into the atmosphere that it could block out the sun, this could possibly last for months, along with the flooding they probably wouldn't stand a chance.

 

Scientists can predict the sounds they made by the size and shape of their bones.

Mega-death is clear - around thwo thirds of the species. The cause is less clear - I like meteors - see above. The Daily Telegraph is carrying a story that in Science, this week they say it is volcanic activity

The fact is, no-one knows.  Certain evidence shows a change in the Earth's climate (e.g. fossils of new trees suddenly appear at the time, which could survive a colder climate).  What caused the change?  Some evidence suggests a meteor falling to Earth (e.g. a layer of dark sediment has been found which is thought to have covered much of the Earth's surface).  But nobody knows for certain.  Scientific 'evidence' is only available information, not incontrovertible , unmistakable truth.

[bernardo]

It was a combination of factors - meterorite impact, climate change, volcanic activity - which brought about a long-term mass extinction.  It was probably the meteorite which finished off the job, but the mass-extinction had already been under way for a few million years before 65 million years ago.

It was the fact that they were not very good at sex according to the article in the latest edition of Viz.

Apparently the Brachiosaurus was unimaginative in bed.

Buy it, LOL.
