In the mammals alone, these three cusps pass into higher stages of evolution,
through what is called "trituberculy" in which these cusps form a triangle. The
discovery of primitive wide-spread trituberculy, by Cope, was a great step forward
.
American Association for the Advancement of Science, 1894
Osborn is, however, fully convinced of the ultimate triumph of the theory ; and,
indeed, goes so far as to state that, in his opinion, " the evidence in favour of it is
so overwhelming that primitive trituberculy is no longer an hypothesis or a theory,
...

In a preliminary discussion of the theory of trituberculy, he shows that the tri-
tubercular molar is the primitive type for Primates as for other Mammalia, and
discusses the origin of this type of tooth. He then reviews critically what is known
of fossil ...
