The ontogenetic trajectory of a marginal jawbone of Lophosteus superbus (Late Silurian, 422 Million years old), the phylogenetically most basal stem osteichthyan, visualized by synchrotron microtomography, reveals a developmental relationship between teeth and dermal odontodes that is not evident from the adult morphology. The earliest odontodes are two longitudinal founder ridges formed at the ossification center. Subsequent odontodes that are added lingually to the ridges turn into conical… Expand

Oral and Palatal Dentition of Axolotl Arises From a Common Tooth-Competent Zone Along the Ecto-Endodermal Boundary
The results indicate that a single tooth-competent zone gives rise to both dental arcades of a complex tetrapod dentition, and propose that the ecto-endodermal boundary running through this zone should be accounted for as a potential source of instruction factors instigating the onset of the odontogenic program.

Diverse stem-chondrichthyan oral structures and evidence for an independently acquired acanthodid dentition
It is shown that the dentigerous jaw bones of disparate genera of ischnacanthids are united by a common construction, being growing bones with non-shedding dentition, and that this taxon is deeply nested within an edentulous radiation, representing an unexpected independent origin of teeth. Expand
Paleontology: There are more placoderms in the sea
Fossil fish from the Silurian of China, including the newly described Bianchengichthys micros, show a range of anatomical features that question the picture of vertebrate evolution and diversification. Expand


Comparison of teeth and dermal denticles (odontodes) in the teleost Denticeps clupeoides (Clupeomorpha)
This close structural agreement between teeth and odontodes in Denticeps suggests that 1) competent cells from the same (ecto)mesenchymal population might be involved and 2) the genetic control of the developmental processes could be identical. Expand
Retention of fish-like odontode overgrowth in Permian tetrapod dentition supports outside-in theory of tooth origins
It is shown that, unlike the well-known one-to-one replacement patterns of marginal dentition, the palatal dentition of the early Permian tetrapods, including the dissorophoid amphibian Cacops and the early reptile Captorhinus, is overgrown by a new layer of bone to which the newest teeth are then attached.

Vascularization and odontode structure of a dorsal ridge spine of Romundina stellina Ørvig 1975
Detailed descriptions of the microstructure and growth of a dorsal ridge spine from the acanthothoracid placoderm, Romundina stellina, are provided using virtual three-dimensional paleohistological datasets and indicate that the spine grew differently from the dentinous fin spines from extant and fossil chondrichthyans.

Evolution of patterns and processes in teeth and tooth-related tissues in non-mammalian vertebrates.
The evolutionary links that exist between odontodes and organs that are phylogenetically related to them (teeth and scales) suggest the use of comparative approaches to study these structures, and the current state of knowledge on developmental mechanisms involved in non-mammalian odontogenesis is reviewed.

Evolution of development of the vertebrate dermal and oral skeletons: unraveling concepts, regulatory theories, and homologies
It is concluded that Reif's theory is close to a universal theory of the evolution of development for the dermoskeleton and dentition, and additional components of theory are tested and extended in light of data on the development of the chick feather array. Expand
Structure and Development of the Odontodes in an Armoured Catfish, Corydoras aeneus (Siluriformes, Callichthyidae)
This work studied the odontodes fixed on the scutes in a growth series of Corydoras aeneus using light, scanning and transmission electron microscopy to compare odontode with tooth development, structure, attachment to a bony support and replacement. Expand
Development of cyclic shedding teeth from semi-shedding teeth: the inner dental arcade of the stem osteichthyan Lophosteus
The numerous cushion-shaped tooth-bearing plates attributed to the stem group osteichthyan Lophosteus superbus display a previously unknown and presumably primitive mode of tooth shedding by basal hard tissue resorption, which broadens understanding of the development of the gnathostome dental systems and the acquisition of the osteICHthyan-type of tooth replacement.

Scales and Tooth Whorls of Ancient Fishes Challenge Distinction between External and Oral ‘Teeth’
The new findings reveal, for the first time, how polyodontode scales grow in 3D in an extinct bony fish and show that dentition-like odontode patterning occurs on scales and that the primary patterning unit of a tooth whorl may be the bony base rather than the odontodes it carries. Expand
The stem osteichthyan Andreolepis and the origin of tooth replacement
A three-dimensional virtual dissection of the dentition of a 424-million-year-old stem osteichthyan, Andreolepis hedei, is reported, using propagation phase-contrast synchrotron microtomography, with a reconstruction of its growth history. Expand
The odontode explosion: The origin of tooth‐like structures in vertebrates
It is shown how teeth can form equally from any epithelium, be it endoderm, ectoderm or a combination of the two and that the gene expression programs of oral versus pharyngeal teeth are remarkably similar. Expand
