Dinosaur Size Records Quiz – Giants and Miniatures

Dinosaurs ranged from chicken-sized hunters to the largest land animals ever. Titanosaurs such as Argentinosaurus and Patagotitan from Argentina may have weighed 60 to 70 tonnes or more, while sauropods like Supersaurus stretched over 30 meters long.

Among predators, Spinosaurus may have been the longest, with Tyrannosaurus rex and Giganotosaurus among the heaviest. At the other extreme, Compsognathus was the size of a chicken and Microraptor the size of a crow. The bee hummingbird is the smallest living dinosaur.

Giant dinosaurs reached their size through fast growth, hollow bones and efficient breathing. Even so, their eggs stayed relatively small because thick shells would stop embryos from breathing. Size estimates change as new fossils are found.
