User: Historically, what are the largest animals on earth? Please include dinosaurs
Assistant: The largest animals to roam the earth were the dinosaurs. Of these, the Sauropods were the largest family of dinosaurs. Sauropods were herbivorous. The Diplodocus was the longest dinosaur found with a complete skeleton with a length of 26 metres or 85 feet.

Larger dinosaurs did exist but only individual bones have been found.
