It was collected in the CTA-27 Locality (or Maquía locality), from the uppermost part of the Yahuarango Formation, dating to the latest Lutetian stage of the late Middle Eocene, about 41 million years ago. It was a tiny rodent as its body mass estimated at approx. 40 g. A cladistic analysis found it to be the basalmost known caviomorph, and one of the oldest (the other being Cachiyacuy from the same locality).[1]EtymologyCanaanimys was first named by Pierre-Olivier Antoine, Laurent Marivaux, Darin A. Croft, Guillaume Billet, Morgan Ganerød, Carlos Jaramillo, Thomas Martin, Maëva J. Orliac, Julia Tejada, Ali J. Altamirano, Francis Duranthon, Grégory Fanjat, Sonia Rousse and Rodolfo Salas Gismondi in 2012 and the type species is Canaanimys maquiensis. The generic name is derived from Canaan, name of a local Shipibo native community, and mys, Greek for "mouse". The specific name is named after its finding place.[1] References{{Portal|Paleogene|Paleontology|Peru|Prehistoric mammals|Prehistory of South America}}1. ^1 2 {{cite journal |author=Pierre-Olivier Antoine |author2=Laurent Marivaux |author3=Darin A.
