In comparison to the T'Rex how large was the brontosaurus and where was it on the food chain?

Answer by  Alicette (139)

The brontosaurus was longer (70-90 ft) than the T-Rex and at the hips it could be, but was not always, taller. It was heavier, between 33-38 tons, the T-Rex averaged around 5-7 tons. The brontosaurus was an herbivore and due to its size was rarely attacked.

Brontosaurus is about twice as long as TRex and much taller. They would never be relevant to one another on a food chain since they existed in different time periods.
