Aldabrachelys abrupta

Turtle egg.

Aldabrachelys abrupta It is an extinct species of cryptodira turtle.

​Cryptodirans differ from pleurodirans, or lateral-necked turtles, in that they only lower their neck and contract it directly, straight, to hide it within the bone shield, instead of turning the neck and head laterally to hide it within the bone shield.

It was a large species, approximately 115 cm in length, and was originally one of six species of tortoise endemic to Madagascar. It occupied the coast and colder highlands of Madagascar, where it fed on shrubs and low branches.
