The largest animal ever to have lived on Earth is the dinosaur Argentinosaurus, a hulking 70-ton behemoth that roamed the Earth during the Late Cretaceous period, approximately 90 million years ago. This massive dinosaur was around 100 feet long and stood as tall as a four-story building, making it one of the largest land animals in history.

Argentinosaurus was a sauropod, a group of long-necked, herbivorous dinosaurs that were characterized by their massive size and distinctive body shape. These creatures had thick, columnar legs, long necks, and small heads, and were able to consume vast amounts of vegetation in order to fuel their massive bodies.

Despite its impressive size, Argentinosaurus was not the longest dinosaur ever discovered. That title goes to the slightly smaller Seismosaurus, which was estimated to be around 150 feet long. However, Argentinosaurus remains the largest known land animal in terms of overall mass, and its discovery has shed new light on the incredible diversity of life that once existed on our planet.
