None of the known Mesozoic mammals appear to have been 
truly herbivorous. 
Stercognathus, which has been considered’ 
as such, from its molar teeth, cannot fairly be regarded as evi- 
dence, since it was based, not upon part of a lower jaw, as 
described by Owen, but upon a fragment, evidently the posterior 
portion of the maxillary, and the teeth resemble the superior 
molars of some insectivorous forms.
