As cold blooded creatures they were always going to be at the mercy of a severe change in the climate. Also their size was against them. The planet was obviously much warmer and enjoyed are fairly stable more tropical environment with lots of food and easily obtainable to sustain such large creatures.
I suppose without the intervention of a huge meteor or asteroid collision that blotted out the sun for so many years it is possible that they would have continued t evolve. Although as the planet continued to cool and the continents continued to drift further apart then the idea climate for them would have continued to shrink. Undoubtedly they would have got much smaller as their living area and diet changed.
Many think that crocodiles and alligators are perhaps good examples that the dinosaur is still with us as are the birds, take a closer look at a bird skeleton, is that not a dinosaur in miniature?
Some scientists and non-scientists think that at least a few of them did - by becoming small and producing a portion of today's reptiles. I don't know, myself, but think it's a possibility.
Birds are thought to have evolved from dinosaurs...
Dinosaurs created by human beings like the gene splicing of today performed back in the day and has evolved into several hundred or thousands or millions of flesh eating animals. These cross breaded animals suffered severe pain in their deformed bodies they were not happy creatures. I believed they were wiped out for a reason for compassion of their race and for our own human survival.
They would have destroyed all living creatures and inter breaded and formed more ferocious animals.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
