Species

C. amazonensis

Canaanimico is an extinctgenus of medium-sizedNew World monkeys from theLate Oligocene (approximately 26.5 Ma,Deseadan in theSALMA classification) fossiliferousfluvio-lacustrineChambira Formation of theUcayali Basin inAmazonianPeru. The genus was described by Marivaux et al. in 2016 and thetype species isC. amazonensis.[1][4]

Classification

[edit]

Marivaux et al. placed the genus in thesubfamilySoriacebinae,[1] of the familyHomunculidae,[3] while Silvestro et al. (2017) attribute anincertae sedis status for the family and subfamily to the genus.[2] Marivaux et al. proposed a close relation with theMiocene South American generaSoriacebus (Santacrucian) andMazzonicebus (Colhuehuapian).[5]

Description

[edit]

Canaanimico was described by Marivaux et al. on the basis of two isolated uppermolars collected at the Contamana fossil locality. The authors inferred that based ondental microwear patterns recorded on one upper molarCanaanimico possibly was a fruit and hard-object eater.[1] Silvestro et al. estimated a body mass of 2,000 grams (4.4 lb) forCanaanimico, making it a medium-sized New World monkey.[6]

Paleoecology

Location of the Chambira Formation in Peru

Fossils ofCanaanimico were found in theLate Oligocene (Deseadan)Chambira Formation of theUcayali Basin in Amazonian Peru. The formation, a sequence of redclaystones andpaleosols with intercalatedconglomerates andsandstones,[7] andgypsum layers,[8] has been dated on the basis ofzircons in atuff bed in the formation, providing an age of 26.56 ± 0.07 Ma.[9] The formation was deposited in atectonically relatively calm[10] tropicalfluvio-lacustrineenvironment withoxbow lakes.[11][12]

The Chambira Formation has provided a rich mammal assemblage ofChambiramys shipiborum,C. sylvaticus,Deseadomys cf. arambourgi,Loretomys minutus,Palaeosteiromys amazonensis,Plesiosteiromys newelli,Scleromys praecursor,Ucayalimys crassidens,Abderites sp.,aff.

Additionally,crocodylians andturtles of?Balanerodus sp.,Podocnemis sp.,cf. Purussaurus sp.,cf. Sebecus sp., and indeterminatefrogs,Booidea,Caimaninae,Colubroidea,Gavialoidea andsnakes were found in the formation, as well as fossil fishes ofcf. Hydrolycus sp.,Leporinus sp.,cf. Phractocephalus sp.,Potamotrygon sp., and indeterminateActinopterygii,Cichlidae,Erythrinidae,Loricariidae andPimelodidae.[14][15]
