Chemical resistance
The human body is 100% chemicals. The food we eat is 100% chemicals. What we drink, be it water or Scotch whisky, is 100% chemicals. The drugs we take, illegal or prescribed, are 100% chemicals. The air we breathe is 100% chemicals. The Earth we live on is 100% chemicals. The TV you watch is 100% chemicals. The sofa you sit on is 100% chemicals. Without chemicals the Earth or any life form would not exist.
Dinosaurs evolved on Earth thousands of millions of years after planet Earth came into being. Presumably the chemicals from which dinosaurs evolved were on the Earth when it came into being, though some may have arrived on asteroids later.
