Question about dinosaurs

[FSM with Cheddar]

Anyway there is no tree of life any more, so perhaps a dung beetle made sweet love with a dinosaur and out popped a crocodile

If you ever need to google something there's a cast iron guarantee that you will find the most moronic answers on Yahoo! …I wondered what ATW had been up to lately?

Back then it was thought that the oxygen content of air was far greater than what it is today, allowing such massive creatures to evolve.

Most of this O2 was consumed because of some global event, leaving only the those creatures that required less O2 behind.

Essentially the dinosaurs suffocated.

Interesting - never heard that before but makes sense. I did know that the World was going through a process of becoming considerably less hot & wet prior to the meteor so that Dinosaurs were somewhat passe by the time of the meteor. Didn't grass evolve at that time?

Didn't grass evolve at that time?

Grass was invented during the plasticene era as a response to the cooling of the Ozone layer, which in turn was affected by the Atlantic conveyor, which is somwhere near the Falklands I think.
Class B grass became more common as class C grass became extinct, due to a meteor that landed in Siberia.

I much prefer the theory that the plants changed and the dinosaurs all died of constipation.

Correct however as Class B Grass becaome more widespread the Dinosaurs discoered that adding Tobacco would make it go that bit further - shortly after this they stumbled upon an IBM MVS system believed to have originated from outsdie the Solar System - thus their fate was sealed.

My understanding is that the extinction event that killed the dinos shows in fossil records as wiping them out in a short period of time, certainly not millions of years?

The fossil records has gaps of millions of years. The most recent fossil before KT that's not found after KT is still many thousand, if not hundreds of thousands of years bwefore KT. It could be inferred that they all died out actual at the time of the KT layer, and that sound sensible. But it's still an open question and there are other theories.

The fossil record doesn't deal in such short timescales.

And it's not K-T any more, "Tertiary" is deprecated in favour of Cenozoic, so it's K-Cn or something like that. Oh well, I did Palaeontology in 1971 so I'm a bit of a dinosaur myself

I thought the dinosaur fossils were put there by god to test our faith?
