Now you wrote, “you’re a biologist but you don’t know that dinosaurs weren’t reptiles?” Now nowhere, in what I wrote did I say that. What I did was emphasize that Turtles were reptiles, because there are people out there, who don’t know this. I also wrote it in a tentative fashion, because we are never 100% sure. Now let me be more specific than. It is hard to be exact on anything, in the world of science. The more you know, the more you realize there is doubt, and you know very little. There are arguments and discussions. When is something exact? When is it a hypothesis? When is it a Theory? When is it a law? When is something provable? There have even been arguments, that some dinosaurs may have been warm blooded, and we are clueless about their thermoregulation and whether what we consider a reptile today, would be considered a reptile 200 million years ago.
There are arguments being made that Turtles were dinosaurs because they first appeared in the Triassic period. There are also arguments they need to get their own special group. Now less than 2 years ago there was a proposed revision of the dinosauria by Baron, Norman, and Barrett that has made things rather confusing because they want to readopt some Huxley concepts. Basically, nothing is exact or proven. So some people tend to speak tentatively, about things that others just assume are facts.
