Megalochelys ("great turtle") is an extinct genus of tortoises that lived from the Miocene to Pleistocene. They are noted for their giant size, the largest known for any tortoise, with a maximum carapace length of over 2 m (6.5 ft) in M. atlas .
The largest extant turtle is the leatherback sea turtle (Dermochelys coriacea), reaching a maximum total length of 3 m (10 ft) and a weight of 961 kg (2,119 lb). [1] [96] The second-largest extant testudine is the Loggerhead sea turtle. It tends to weight slightly more average weight than the green sea turtle, and reaches more massive top sizes.
Both Megalochelys and Titanochelon reached sizes substantially greater than modern giant tortoises, with up to 2.4 m (7 ft 10 in) and 2 m (6 ft 7 in) shell lengths respectively. The phenomenon of animal species evolving in cache to unusually large size on islands (in comparison to continental relatives) is known as island gigantism or insular ...
Tortoises removed include members of Aldabrachelys (from the Seychelles and Madagascar), Astrochelys [2] (Madagascar), Chelonoidis (South America and the Galápagos Islands), Stigmochelys [2] and Centrochelys (Africa), and the extinct Megalochelys (southern Asia). These species are also unique for their ability to remember patterns and spatial ...
The Santiago Island giant tortoise (Chelonoidis niger darwini), also known commonly as the Santiago giant tortoise [3] and the James Island tortoise, is a subspecies of Galápagos tortoise in the family Testudinidae.
In prehistoric times, a large insular radiation of giant Chelonoidis existed on many West Indian islands, including the Bahamas, Greater Antilles and Lesser Antilles. While some species such as those on Curaçao, Anguilla, and Barbados are thought to have gone extinct during the Late Pleistocene, other species such as those on the Greater Antilles and the Bahamas are thought to have been ...

Stylemys (meaning "pillar turtle") is the first fossil genus of dry land tortoise belonging to the order Testudines discovered in the United States. The genus lived in temperate to subtropical areas of North America, Europe, and Asia, based on fossil distribution. [1] The genus was first described in 1851 by Joseph Leidy. [2]
