Crania Similar to modern day
rodents,
Stylinodon had continuously growing teeth. All 6
molars of
Stylinodon are similar in shape, being cylindrical, and they have a thin layer of
enamel. The
incisor teeth of
Stylinodon were large and curved. The rest of the skull is short, with prominent
temporal fossae and a generally small
brain cavity. The
sagittal crest is joined with the
occipital plane at the top and the skull lacks a prominent
occipital condyle, as well as having no paroccipital processes.The lower jaw of
Stylinodon is massive and deep, with fused
symphysial sutures and large
condyles being especially notable features. The
ramus is similarly robust.
Postcrania Postcranial remains of
Stylinodon suggest a degree of
fossoriality due to the robustness of the skeletal elements. It is suspected that the
sacrum of
Stylinodon consisted of 3
vertebrae. == History of research ==
