- 摘要:
- ms, and differences in puncture performance also occurred among tooth types; however, few patterns emerged. In some cases, broader triangular teeth were less effective

- 摘要:
- Teeth were an important innovation in vertebrate evolution but basic aspects of early dental evolution remain poorly understood. Teeth differ from
Data from: Dental ontogeny in extinct synapsids reveals a complex evolutionary history of the mammalian tooth attachment system

- 摘要:
- The mammalian dentition is uniquely characterized by a combination of precise occlusion, permanent adult teeth, and a unique tooth attachment syste
Data from: Extreme dentition does not prevent diet and tooth diversification within combtooth blennies (Ovalentaria: Blenniidae)

- 摘要:
- , coral polyps, polychaetes, and pieces of other fishes), are blenny teeth indeed monomorphic? Or does tooth variation associated with diet still exist
Data from: Evolutionary origins of teeth in jawed vertebrates: conflicting data from acanthothoracid dental plates (‘Placodermi’)

- 摘要:
- for evolutionary origins of teeth, particularly with respect to the Arthrodira. The arthrodires represent a derived group of placoderms; the dentition of other mor
Data from: Sauropod tooth morphotypes from the Upper Jurassic of the Lusitanian Basin (Portugal)
- 负责人:
- DOI:
- doi:10.5061/dryad.s211m
- 摘要:
- morphotypes represented in this region. A large sample of teeth, both unpublished and published, is described and discussed here. Four main tooth morphologies
Data from: A peculiar tooth renewal in a Jurassic ray-finned fish (Lepisosteiformes: ?Scheenstia sp.)

- 摘要:
- tooth replacement mode that is, as far as we could trace back in the literature, unique among vertebrates. The formation of the replacement teeth comprises a 180

- 摘要:
- . Differentiation of form is evident among specimens only after the second volution or roughly the 85th tooth. Helicoprion davisii has widely-spaced, stout teeth
