The concept of ovarian reserve describes the natural oocyte endowment and is closely
associated with female age, which is the single most important factor influencing …

The integument forms a number of different types of mineralized element, including dermal
denticles, scutes, ganoid scales, elasmoid scales, fin rays and osteoderms found in certain …

Elucidation of the mechanisms controlling early development and organogenesis is
currently progressing in several model species and a new field of research, evolutionary …

Here for the first time we use micro-computed tomography (μCT) scanning techniques to
study dental replacement in the Early Triassic cynodont Thrinaxodon liorhinus. We analyzed …

Dental morphology and patterns of tooth replacement in representatives of the clade
Pliosauridae (Reptilia, Sauropterygia) are evaluated in detail. The jaws of one basal …

The dentition of osteichthyans presents an astonishing diversity with regard to the
distribution of teeth in the oral cavity, tooth numbers, arrangements, shapes, and sizes …

Tooth counts are commonly recorded in fossil diapsid reptiles and have been used for
taxonomic and phylogenetic purposes under the assumption that differences in the number …

The placodonts of the Triassic period (~ 252–201 mya) represent one of the earliest and
most extreme specialisations to a durophagous diet of any known reptile group …

Continuous tooth replacement is common for tetrapods, but some groups of acrodont
lepidosaurs have lost the ability to replace their dentition (monophyodonty). Acrodonty …

The molecular and developmental factors that regulate tooth morphogenesis in
nonmammalian species, such as snakes and lizards, have received relatively little attention …
