Answer:

3. Mesozoic 4.dogs

Explanation:

3.Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.

4.Dogs have a strong sense of smell

Scientists guess the dog's sense of smell is somewhere between 10,000 to 100,000 times more acute than ours. One of the reasons a dog has such better smelling ability than us is the number of scent receptors. For every scent receptor a human has, a dog has about 50.
