Re: Why did small dinos become extinct?
That is a rather simple hypothesis, which doesn't
explain more than it does. It's more likely that there
were (and I hate this term, it makes me think of GCSE
humanities exam questions) a number of factors
involved in the extinction of the non-avian dinosaurs,
which I'm sure some of our colleagues who work at that
end of the Cretaceous can tell us about!
And it wasn't just dinosaurs, nobody ever thinks of
