The most dominating species of all time

The most dominating species so far was the dinasoars because they were dominating for almost 160 million years us humans have so far dominated for 6000 to 7000 years so i think so Thar we cant even judge our self better than the dinasoars but i do say we are cleverer than them. The dinasoars should really have had bigger brains because their brains were little.
