 Radiocarbon dating has placed some of the finds in the late Pleistocene.Fossilized remains of this animal have been found practically in every part of the island, but especially in deposits in caves or volcanic pipes of the island, where it often appears together with remains of other species such as the giant lizards ("Gallotia goliath").In particular, its bony remains have been discovered in large amounts in the deposit of Buenavista del Norte (in the northwest of Tenerife).
