Pattonomys

Pattonomys is a genus of rodent in the family Echimyidae,[1] named after American mammalogist James L. Patton. It contains the following species:

  • Bare-tailed armored tree-rat (Pattonomys occasius)
  • Speckled spiny tree-rat (Pattonomys semivillosus)

Phylogeny

Pattonomys is the sister genus to Toromys. These taxa are closely related to Echimys, Phyllomys, and Makalata, reflecting the fact that Pattonomys occasius and Toromys grandis have formerly been placed in Makalata by some authorities.[2] In turn, these five genera share phylogenetic affinities with a clade containing the bamboo rats Dactylomys, Olallamys, Kannabateomys together with Diplomys and Santamartamys.[3]

gollark: It's a cool statistical phenomenon. Applies to lots of things.

gollark: So if you have a scatterplot of appearance goodness/personality goodness, what would otherwise be an ellipse of uncorrelation has the bottom left removed and it looks negatively correlated.
gollark: Those things are quite possibly entirely uncorrelated, but you probably only notice/consider people where the sum of appearance and personality is above some threshold.
gollark: Fun fact: this is known as Berkson's paradox.
