Evolution of Mammalian Molar Teeth: To and from the ...
stages are " haplodont," " triconodout," " tritubercular," so the retrogressive stages
reverse this order, passing from " tritubercular " back to " tricono- dont " then into "
haplodont." Another view therefore is that such primary forms have been ...
Henry Fairfield Osborn, William King Gregory, 1907
The above table shows somewhat indefinitely, but none the less positively, the
general progression of the Mammalia, to and from the primitive tritubercular type.
As already stated, even with our present very limited knowledge, certain stages ...
Henry Fairfield Osborn, 1879
Considerable significance, therefore, attaches to the question as to whether the
superior true molars of Homo sapiens are quadritubercular or tritubercular. The
inferior molars are also either quadritubercular or quinquetubercular ; but less ...

Fossil Vertebrates in the American Museum of Natural History
In 1888 Professor E. D. Cope, in his article “On the Tritubercular Molar in Human
Dentition,” 1 maintained that “first, the quadritubercular type of molar crown,
illustrated by the first superior true molar of man, belongs to the primitive form
from ...

The American Naturalist
It is true we find many more recent " triconodont " teeth, the lower molar of
Mesonyx for example, which are positively known to be of tritubercular origin.
Richard Owen compared the lower molars of Thylacinua with those of
Triconodon, but we ...

Bulletin of the American Museum of Natural History
(3) The lower molars of Diademodon have a transverse ridge analogous to a
protolophid, and if the external tip of this ridge were produced dorsally it would, in
mastication, occupy precisely the relations of a protoconid in a tritubercular molar
.
According to the tritubercular theory, the so-called quadri- tubercular superior
molars (composed of four principal cusps), were derived from the tritubercular
pattern by the addition of a postero-intemal cusp (hypocone). In order to test the
value ...

The Primary Factors Of Organic Evolution
It is further questioned by Forsyth»Major, whether the tritubercular molar has
been derived from the triconodont. He believes, on the contrary, that it is derived
from the multitnbercular type by reduction. There are two objections to this view: (I
) ...
