Question: how big were the dinosours

Jake answered on 27 Nov 2020:

Some were absolutely enormous! The Argentinosaurus was 30m long, weighed around 75 tonnes, and was the largest animal to ever walk on land. Some were tiny though, like Compsognathus which was about the size of a chicken, and the hummingbird (which like all birds is a living dinosaur!) They came in all shapes and sizes in between too!
