エル・イエロ島
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. 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.
