This is an accepted version of this page Brachylophus gibbonsi is an extinct species of large (~1.2 m long) iguanid lizard from Tonga in the South Pacific Ocean.
[1] Its remains have been found associated with cultural sites on Lifuka, four other islands in the Haʻapai group, and Tongatapu.
[1][2] It was consumed by the early Tongans and probably became extinct within a century of human colonization of the archipelago 2800 years ago.
[1] An even larger Fijian iguana of the genus Lapitiguana was also formerly present, and also became extinct shortly after the arrival of humans.
[4][5][6] Another theory is that the South Pacific iguanas descend from a more widespread lineage of (now extinct) Old World iguanids that diverged from their New World relatives in the Paleogene, migrated to either Australia or Southeast Asia, and then somehow made their way to the Fijian and Tongan archipelagos.
