The Largest Dinosaur Ever Discovered: Patagotitan Mayorum

The title of the largest dinosaur ever discovered, based on the most complete fossil evidence, currently belongs to Patagotitan mayorum. While other contenders like Argentinosaurus may have been slightly heavier, Patagotitan has a more robust fossil record, allowing for more accurate size estimations.

Discovered in Patagonia, Argentina, in 2014, Patagotitan was a long-necked, long-tailed herbivore belonging to the group of sauropods known as titanosaurs. Its sheer scale is difficult to comprehend:

• Length: Approximately 37 meters (122 feet) – longer than three school buses end-to-end.
• Height: Around 6 meters (20 feet) at the shoulder, with its neck reaching even higher.
• Weight: Estimated to be around 69 metric tons (76 tons) – equivalent to about 10 African elephants.

The discovery of Patagotitan has provided invaluable insights into the biology and evolution of giant sauropods, revealing how these incredible creatures grew to such immense sizes and supported their massive bodies.

Pro tip: When discussing the "largest" dinosaur, it's important to distinguish between length, height, and mass. Also, the completeness of fossil remains significantly impacts the accuracy of size estimates. More complete skeletons, like that of Patagotitan, allow for more reliable scientific conclusions than those based on fragmentary evidence.
