Diphyodont
the distolingual cone or cusp of the talonid of the mandibular molars
Entoconid
bearing or supporting teeth; supplied with teeth; also containing teeth, as a dentigerous cyst
Dentigerous
pertaining to the jaw cheek
Gnathic-
hinged, as the jaw articulation of the carnivore; a joint that allow motion around an axis
Ginglymoid-
the first, single coned tooth observed in prehistoric reptiles according to the premolar-molar analogy theory
Eocone
attachment of the teeth by implantation in a bony socket or alveolus

the distobuccal cusp of mandibular molars
Hypoconid
the distal cusp, the fifth cusp of mandibular molars
Hypoconulid
Having maxillary and mandibular teeth of the same size and pattern.
Isognathous
Having the crowns of the teeth formed in transverse or longitudinal crests or ridges, as in the herbivore.
Lophodont
The distobuccal cone or cusp of the maxillary molars.
Metacone
The distolngual cone or cusp of the primitive mandibular molars, becoming mesiolingual due to the loss of the paraconid cusp in the Primates.
Metaconid
Small, intermediate cusp between the metacone and the protocone of the maxillary molars.
Metaconule
Having only one set of teeth

Perissodactyle
Having multiple lophs or cusps.
Polylophodont
Leaning or extending forward; like the incisors in Insectivores.
Procumbent
Having multiple sets of teeth.
Polyphyodont
The lingual cusp of a maxillary premolar, the primitive reptilian cone or cusp of a maxillary tritubercular molar, i.e., the lingual cusp or the mesiolingual cusp of a maxillary molar.
Protocone
Having four tubercles or cusps.
Quadritubercular
The primitive buccal cusp of a mandibular premolar; the primitive reptilian cone or cusp of a mandibular tritubercular molar, or the mesiobuccal cusp of a mandibular molar.
Protoconid
Artiodactyl animals that chew the cud, as oxen, sheep, goats, deer, and others.
Ruminantia or Ruminants

To cut as with a pair of scissors.
Sheer
Having longitudinal crescent shaped ridges, as a molar tooth of the Artiodactyla (ox, deer, sheep, hog, etc.).
Slenodont
Having the same shape or size on both sides.
Symmetrical

Talon
Persisting alveolar sockets that are independent of the presence or teeth, as in crocodiles and alligators.
Thecodont
The heel, or distobuccal portion of a mandibular molar crown, upon which may develop the entoconid, the hypoconid and the hypoconulid.
Talonid
Having three cones or cusps in a linear arrangement, the central one the largest.
Triconodont
Jurassic animals, unmistakably mammals, which show a triconodont condition of the molars.
Triconodonta
See triconodont.
Tribosphenic
The arrangement of the first three cones or cusps of a mandibular molar (Protoconid, Paraconid + Metaconid).
Trigonid
The arrangement of the first three cones or cusps of a maxillary molar (Metacone, Paracone + Protocone).
