The Record-Breaking Turtle, Known for Its Massive Size, Holds the Title of the Biggest Ever Recorded

Giant Turtles of the Past: Archelon and Leviathanochelys aenigmatica

In the distant past, during the Late Cretaceous period, the world was home to some truly colossal creatures. Among these behemoths were two species of turtles that dwarfed any living today: Archelon and Leviathanochelys aenigmatica.

Let's start with Archelon, the largest turtle ever documented. With a wingspan of about 5 meters (16.5 feet) from the end of one outstretched front flipper to the other, and a length of approximately 4.6 meters (15 feet) from the tip of its beak to the end of its tail, this prehistoric reptile was an impressive sight. Weighing more than 2,040 kilograms (4,500 pounds), which is roughly the same weight as an adult male rhinoceros, Archelon was a force to be reckoned with. Its beak was prominent and hooked, suggesting a powerful, deadly bite.

Archelon lived in the Western Interior Seaway, a now non-existent stretch of sea that once divided North America. It is believed that this ancient sea turtle may have used its powerful bite to prey on mollusks and soft-bodied sea creatures such as jellyfish.

Moving on to Leviathanochelys aenigmatica, the largest turtle ever to have swum in European waters. Discovered in northeastern Spain, L. aenigmatica measured approximately 4 meters (13 feet) in length. Its discovery dispelled previous suspicions that giant turtles weren't to be found in Europe. The name Leviathanochelys aenigmatica references the biblical marine monster Leviathan.

The largest turtle currently living is the leatherback sea turtle (Dermochelys coriacea). Despite not being as large as Archelon, it is still significant in size. The leatherback sea turtle can reach up to two meters in length and weigh nearly one ton. It is quite graceful in the water, moving in a similar way to penguins.

Intriguing as these ancient creatures are, they serve as a reminder of the vast array of life that has existed on our planet and the mysteries that are yet to be uncovered. The study of these prehistoric turtles provides us with a fascinating glimpse into the past and offers valuable insights into the evolution of life on Earth.
