Justification: This species is listed as Extinct as it is known only from a subfossil record which showed that is recently occurred on the island and was likely eradicated by numerous invasive species which have been introduced to the island. Exhaustive surveys in suspected habitat throughout its historic range have failed to record an individual. |
|
| Range Description: | This species was found on the island of Santa Cruz of the Galápagos Islands. It is known only from late Quaternary and subfossil cave deposits. This species is considered to have very recently become extinct (Steadman and Ray, 1982; Musser and Carleton, 2005). |

| Population: | The chronology of extinction of Megaoryzomys curioi is very speculative. There are no absolute age determinations available as yet for any mammal-bearing fossil deposit in Galápagos. The possibility of the involvement of feral dogs, cats, pigs, and black rats in its extinction is also suggestive of a recent extinction (Steadman and Ray, 1982). |
| Habitat and Ecology: | The species is through to have occurred in shrub forests. |
| Systems: | Terrestrial |
| Major Threat(s): | This species is extinct. |
| Conservation Actions: | This species is extinct. |
