Extinct reptiles

The most famous members of the reptile family, the dinosaurs, became extinct as a result of the impact of a huge meteor, which changed the Earth’s environments, and as a result, many species could not survive. In the last few centuries however almost all known reptile extinctions can be attributed to human activity – either directly, through overhunting, or indirectly, by introducing predatory species, or altering the habitat the reptiles rely on for survival. Mariner’s often relied on reptiles (particularly tortoises) on strategic islands as a source of food, and in the nineteenth century in particular severely depleted some populations of reptiles, and completely wiped out others. Once we lose them, we will never get them back.

Below is a list of recorded extinctions of reptile species, with their locality, date of last sighting, and the reason for their disappearance. Human activity has been responsible in all known cases. There is also the Black Soft-shell Turtle (Aspideretes nigricans), which is extinct in the wild but can be found in a single artificial temple pond in Bangladesh.
