The largest dinosaur that scientists have discovered to date is the titanosaur Patagotitan mayorum.
Discovering the Colossus of Patagonia
Patagotitan mayorum is an extraordinary long-necked, plant-eating dinosaur that lived over 100 million years ago during the Late Cretaceous period. Its remarkable fossil remains were unearthed in what is now Patagonia, Argentina, making it a monumental find in the world of paleontology. This immense creature represents the peak of dinosaurian gigantism among known species.
Unveiling Patagotitan's Scale
This colossal titanosaur is recognized for its immense size, estimated to have weighed upwards of 70 metric tons (approximately 150,000 pounds) and stretched an incredible 37 meters (122 feet) from head to tail. Its sheer scale makes it the heaviest and one of the longest land animals known to have ever walked the Earth.

Why Patagotitan Reigns Supreme
Patagotitan mayorum holds the title of the largest dinosaur due to the completeness and sheer size of the fossil evidence discovered. While other contenders for the largest dinosaur exist based on more fragmentary remains (such as Argentinosaurus or Supersaurus), Patagotitan's more extensive fossil record provides a stronger basis for its size estimates, solidifying its position as the largest scientifically documented dinosaur. It represents a truly awe-inspiring example of evolutionary grandeur.
