Teeth and dentitions contain many morphological characters which give them a particularly
important weight in comparative anatomy, systematics, physiology and ecology. As teeth are …

This review considers the diversity observed during both the development and evolution of
tooth replacement throughout the vertebrates in a phylogenetic framework from basal extant …

Since their recruitment in the oral cavity, approximately 450 million years ago, teeth have
been subjected to strong selective constraints due to the crucial role that they play in species …

Albanerpetontids are tiny, enigmatic fossil amphibians with a distinctive suite of
characteristics, including scales and specialized jaw and neck joints. Here we describe a …

Tooth implantation provides important phylogenetic and functional information about the
dentitions of amniotes. Traditionally, only mammals and crocodilians have been considered …

To investigate correlation between the ameloblastin (Ambn) amino acid sequence and the
emergence of prismatic enamel, a notable event in the evolution of ectodermal hard tissues …

ABSTRACT The Lower Permian amphibamid Doleserpeton annectens (Temnospondyli) is
of great importance to our understanding of the origin of modern amphibians. Here, we …

Here we take the first look at cellular dynamics and molecular signaling in the developing
snake dentition. We found that tooth formation differs from rodents in several respects. The …

Beaks are innovative structures characterizing numerous tetrapod lineages, including birds,
but little is known about how developmental processes influenced the macroevolution of …

The development of a tooth germ in a precise size, shape, and position in the jaw, involves
meticulous regulation of cell proliferation and cell death. Apoptosis, as the most common …
