They died. All of them.

No one is absolutely sure why, but the best guess is a large meteorite that struck in the Gulf of Mexico. It may have changed the climate enough to make it unlivable for them. (Note : lots of other species went extinct at the same time.)

My opinion is that after the world wide flood discussed in Genesis, the earth's atmosphere changed. Dinosaurs could not thrive in this new climate, and slowly died off.

What humans attack shark moreoften dinosaurs become extinct?

The dinosaurs were extinct long before humans appeared on the earth. The dinosaurs were probably killed off when a giant meteor hit the Yucatan Peninsula in Mexico. The resulting debris from the impact that was put into the atmosphere, created conditions on earth, similar to a "nuclear winter". The dinosaurs could not cope with the sudden change to the earth's environment and died off. Humans fish for sharks, but, not enough to bring about their extinction. Sharks do attack humans, but, it's very rare and does not happen very often.
