Description

Canaanimys is known from the holotype MUSM 1890, a right second molar and from some referred teeth including MUSM 1889, MUSM 1891, MUSM 1892, MUSM 1893, MUSM 1894 and MUSM 1895. 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]

Etymology

Canaanimys 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]

gollark: I think that works too. Though at this point Edge is effectively just reskinned Chromium.
gollark: Apparently Microsoft Teams "requires" Chrome or the desktop app to do voice/video meetings, but it also worked perfectly fine when I just switched the user agent in Firefox.
gollark: Intel's 7nm is said to be (meant to be) similar to other companies' 5nm, at least.
gollark: They have 10nm Ice Lake mobile CPUs, at least.
gollark: They still haven't. So the best thing *shipping* is Ice Lake, which had better IPC but is also on their not-very-good 10nm process and has bad clocks, making it roughly as good as 14nm ones with worse architectures.
