Taxonomy
Plesiobaena putorius was named by Gaffney (1972). Its type specimen is YPM PU 14984, a skull (an almost complete partially crushed skull), and it is a 3D body fossil. Its type locality is Cedar Point Quarry, which is in a Tiffanian fluvial-lacustrine siliciclastic in the Fort Union Formation of Wyoming. It is the type species of Cedrobaena.
It was recombined as Cedrobaena putorius by Lyson and Joyce (2009), Joyce and Lyson (2015).
It was recombined as Cedrobaena putorius by Lyson and Joyce (2009), Joyce and Lyson (2015).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. R. Lyson and W. G. Joyce 2009 | Diagnosed as being within Baenidae by location of the foramen posterius canalis carotici interni between the pterygoid and halfway along the basisphenoid; triturating surface posteriorly expanded with lingual ridge reduced posteriorly; and well-developed pterygoid and basioccipital contact. Part of the Plesiobaena/Palatobaena clade based on greater development of parietal overlying crista supraoccipitalis compared to Eubaena cephalica (Gaffney, 1972), Stygiochelys estesi Gaffney and Hiatt, 1971, and Palatobaena cohen Lyson and Joyce, 2009; deep temporal emargination; no incipient secondary palate; short preorbital skull length compared to Boremys spp. and E. cephalica; jugal exposed in orbital margin. Autapomorphies include: parallel sided parietal overhang overlying supraoccipital; incisura columellae auris loosely enclosed posteroventrally by a dorsal process of the quadrate that contacts the squamosal; frontal and parietal suture located at middle of orbit; relatively thick stapes with the diameter more than double that of other baenids from which a stapes is known; lingual ridge curves laterally. Similarities with Pl. antiqua include: cheek emargination shallow, reaching only to ventral border of orbit. Similarities with Pe. brinkman include: nasals either lost or fuse early with frontals; jugal enters orbital margin; broad medial contact between pterygoids. Differences compared to Pl. antiqua and Pe. brinkman: sulci for scales on dorsal skull roof present; supraoccipital not exposed on dorsal skull roof; dorsally oriented orbits; orbits inset into maxilla. Similarities with Palatobaena spp.: large mandibular condyles; posterior portion of triturating surface greatly expanded; poorly developed pterygoideus externus; dorsally oriented orbits; orbits inset in maxilla. |
