Gallotia goliath (the goliath Tenerife lizard[2]) is an extinct giant lizard species from the island of Tenerife of the Canary Islands, Spain. This reptile lived before the arrival of humans and is believed to have grown to at least 0.9 metres (3.0 ft) long.[3] It was described by the German herpetologist Robert Mertens. Fossils of this lizard have been found in volcanic caves, where they often appear with those of other animals, like the Tenerife giant rat.

Prehistoric Gallotia remains have been assigned to the taxa G. maxima and G. goliath, the former supposedly occurring only on Tenerife, the latter on several islands. It was eventually determined, however, that G. maxima is a junior synonym of G. goliath, and that the latter was close to the El Hierro giant lizard (Gallotia simonyi); supposed goliath specimens from El Hierro, La Gomera, and La Palma (from the Cuevas de los Murciélagos) are probably just extremely large individuals of, respectively, the El Hierro, La Gomera (Gallotia bravoana) and La Palma (Gallotia auaritae) giant lizards.[4] Based on DNA sequence analysis of mummified remains, G. goliath is a valid species that probably was restricted to Tenerife, and apparently was closer to the Tenerife speckled lizard (Gallotia intermedia) than to the El Hierro giant lizard.[5]
