Lizards are reptiles. Tuatara aren't lizards, but a different family, although still reptiles. Turtles are reptiles but not lizards. Snakes are reptiles but not lizards.Dinosaurs are not reptiles nor lizards any more than they are mammals, which are also not lizards or reptiles. Birds too, aren't reptiles, but maybe dinosaurs after all. Pteranodons aren't dinosaurs, nor birds, but something else again. I think they aren't reptiles now either, though. And thus not lizards.
All are (or at least were) probably delicious, and if still existent, are bound to be a main component of some dish or another in Cantonese cooking, where, after all, crocodiles (another reptile, but not a lizard either) are a fish. I think frogs are a kind of chicken in Chinese. If they are endangered, then they are probably a medicine as well.
People in New Zealand don't eat Tuatara any more since the importation of pakeha, although people in Bangladesh would, if they could, along with all the above.
If the Chinese find out about randy Tuataras living for so long, the poor lizards will become a medicine, which can then be a great source of income to the many tuatara farmers living in NZ, along with the third eye they sometimes have while young could be used as a medicine to enhance their psychic powers.
Hope that sorted it all out. A bucket of fried lizard parts, anyone? Want fries with that?
BTW, I solved the world's CO2 issues. Have sent a summary to some scientists who seem impressed, and it is now going the rounds of the skeptics societies, being checked by scientists, engineers, and various luddites of interest. It is doing the rounds as "the shellfish solution". It looks like it really might work. Everyone can now stop arguing and get on with their lives. Send cheques care of Mr N, centre of the universe. Thank you, thank you one and all. Go back to what you were doing. Nothing to see here.
So now you can all rest assured that all possible is done to prevent global warming.
