What was the brontosaurus zord from power rangers?

The Brontozord was not a Power Ranger zord. It was a zord from the TV series "Mighty Morphin Power Rangers" that combined with the other zords to form the Megazord. The Brontozord was a large, green dinosaur-like zord with a powerful tail and a horn on its head. It was piloted by the Green Ranger, Tommy Oliver.
