The lower jaw of Morganucodon
Abstract
The genus Morganucodon is found in Yunnan, China, in normal (non-karstic) sedimentary deposits (Lufeng beds) of probable Rhaetian age; and in Wales in karstic deposits in the Carboniferous Limestone. These latter deposits cannot be younger than Sinnemurian or older than Rhaetic. A new suborder—Morganucodonta—of the Triconodonta is created for Morganucodon and its allies. Morganucodon and Eozostrodon are not synonyms. The lower jaw of Morganucodon resembles closely that of an advanced cynodont, except for the presence of a squamosal-dentary joint in the former. There was no reduction in the functional importance of the reptilian (quadrate-articular) jaw-joint in passing from the cynodont condition to that of Morganucodon. The mechanism of shearing is discussed. The action of the cheek-teeth is pure shear. Primarily, the function of the squamosal-dentary articulation was to resist couples produced by the shearing, thus primitively, the presence of efficient shearing cheek-teeth is associated with a squamosal-dentary articulation. The skull of Morganucodon will be described in a later paper.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
