Geochelone is a genus of tortoises.

Geochelone tortoises, which are also known as typical tortoises or terrestrial turtles, can be found in Africa and Asia. They primarily eat plants.

The genus consists of two extant species:

There are two extinct species that inhabited the Canary Islands:

One extinct species inhabited Malta

And an extinct species in the Balearic Islands:

A number of tortoise species have been recently removed from the genus. This taxon as formerly defined was "polyphyletic, representing at least four independent clades".[4] Tortoises removed include members of Aldabrachelys (from the Seychelles and Madagascar), Astrochelys[5] (Madagascar), Chelonoidis (South America and the Galápagos Islands), Stigmochelys[5] (Africa) and earlier, the extinct genus Megalochelys (southern Asia).

"Self-righting" shell[edit]

The form of the shell of the Indian star tortoise resembles a gömböc, allowing it to turn over when lying upside down very easily.
