Exempel på hur man kan använda MOLARIFORM i en mening

• Extensive pharyngeal tooth pads are present in upper and lower sets, with cardiform and villiform teeth gradually being replaced by molariform teeth as the fish grows larger.
• Spalacotheriidae, which has acute−angled molariform teeth, strongly reduced talonids, and conspicuous anterior and posterior cingulids.
• The two roughly conical teeth in each premaxilla would have been used for nipping off plant material or possibly for defence, while the molariform, polycuspid teeth in the maxillae (at least four in each) could have ground up the food.
• Glossotherium has a layer of cementum surrounding all molariform cheek teeth with some traces on caniniform teeth.
• The teeth are noticeably heterodont in Adamantinasuchus, with a mixture of incisiform, caniniform and molariform teeth.
• marsupium, yet these are generally true of Herpetotherium) that he felt were especially comparable to Didelphis, such as "(1) the strong canine, (2) weak anterior premolar, (3) dominance of the protocone in the premolars, (4) fourth tooth of the series molariform, (5) position of mental foramen under this tooth, (6) identical form of the molars, (7) groove on the jaw suggesting an inflected angle," yet he pointed out several differences, such as "(1) absence of diastemata around the anterior premolar, (2) trend of the mental foramen forward instead of backward, (3) the inflected angle, seeming to begin beneath the molars" (p.
• At the front of the mouth there were two pairs of tusk-like "caniniform" teeth on the upper and lower jaws which are separated from the molariform teeth by a large diastema (gap).
• Like other gobiconodontids, it possessed several speciations towards carnivory, such as shearing molariform teeth, large canine-like incisors and powerful jaw and forelimb musculature, indicating that it probably fed on vertebrate prey.
• Past this toothless region of the snout, there were larger tricuspid (three-pronged) cheek teeth on the maxilla and a large molariform tooth which is elongated in an anteroposterior (front-to-back) direction.
• Its postcanine molariform teeth are tricuspate or tetracuspate and the tooth roots are incipiently divided.
• One, a fragmentary molariform (molar or molar-like premolar—the identities of gondwanathere tooth are poorly understood) is larger and lower-crowned than the Lavanify teeth and the other, which is complete and unworn, is yet lower-crowned and has the surface obliquely oriented.
• The molariform teeth are well suited to shearing food like modern mammalian carnivores (for example, all many species of bears, canids, big cats, hyenas, mustelids, procyonids, mongooses and pinnipeds).
• Among the seven teeth in their sample, Wilson and colleagues tentatively identified five as fourth lower molariforms (mf4)—because gondwanathere premolars and molars cannot be distinguished, they are collectively known as "molariforms"—one as a third lower molariform (mf3) and one as a lower incisor (i1).
• Characteristic features are found in the caniniform and incisiform design of the anterior tooth in each case, as well as in the molar-like (molariform) designed posterior teeth.
• Huang and colleagues observed that the development of molariform teeth occurred independently many times in aquatic animals (including multiple lineages of monitor lizards, moray eels, and sparid and cichlid fish), and thus the frequency among ichthyosauriforms is not unusually high.
• The incisors are rootless and extend lingually along the ventral border of the dentary up to the level of molariform 3, and the molariforms are hypsodont.
• Symmetrolestes is more derived than zhangheotheriids as it had acute−angled molariform teeth with completely developed shearing surfaces, taller crowns on its teeth and more complete cingulids.
• The molariform m2 is intermediate in structure between the triconodont pattern seen in taxa such as Morganucodon (with large triangular cusps in a single row) and the specialized two-row pattern found in the more derived euharamiyidans.
• The mandibular dentition was similar to that of other mylodonts with one anterior canine (caniniform) tooth and three posterior molariform teeth.
• In addition, Proargyrohyrax can be distinguished from Santiagorothia in having the upper and lower premolars more molariform, a larger development of the labial fossettes on the upper premolars, and the widened trigonid and talonid on the third premolar.
