Scientific Name: Cryptoprocta spelea Grandidier, 1902
Common Name(s):
English Giant Fosa, Giant Fossa
Taxonomic Notes: Grandidier (1902) described a large form of Cryptoprocta ferox from subfossil material dating from the presumed Holocene in Madagascar that he referred to the variety spelea. Subsequently, there has been varying opinion on the validity of this taxon. Goodman et al. (2004) examined and analysed 159 subfossil and 32 modern osteological specimens of Cryptoprocta and concluded that this was a valid species that existed on Madagascar in the recent geological past.

Assessor(s): Hoffmann, M. & Hawkins, F.
Reviewer(s): Duckworth, J.W.
This species is listed as Extinct as there is no evidence to suggest that this large species of Cryptoprocta currently survives on Madagascar. It is currently known only from subfossil remains and is believed to have survived at least into the recent geological past.

Geographic Range [top]

Range Description:On the basis of current subfossil evidence, Cryptoprocta spelea occurred at a variety of sites from Lakaton’ny Akanga in the far north near Antsiranana, along the western portion of Madagascar, south to numerous sites at the southern end of the island; it is also recorded on the central highlands at Antsirabe (Goodman et al. 2004).

Number of mature individuals:0
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Given the size of Cryptoprocta spelea, its massive jaws and large carnassial teeth, it must have been a formidable predator and certainly capable of taking larger prey than the extant C. ferox. Evidence suggests that the two forms of Cryptoprocta might have been separated well enough in size to be able to coexist (Goodman et al. 2004).

Use and Trade [top]

Use and Trade: There are no uses at present as this species is extinct.

Threats [top]

Major Threat(s): The reasons for the disappearance of this species on Madagascar (its entire world range) are unknown.

Conservation Actions [top]

Conservation Actions: No conservation actions are needed because the species is extinct.
