Abstract Juvenile material with the main focus on the upper jaw of the fossil predator Hyaenodon was evaluated to study the tooth eruption sequence and to examine the ontogeny of its dentition in detail. The comparison in size of milk to permanent teeth indicates a growth rate of 12–16 % in Hyaenodon. The thin section of a deciduous canine of a North American taxon shows four dental rings. Based on the knowledge of recent carnivores, this implies an age of 3–4 years in the last stage of tooth… Expand

First Radiological Study of a Complete Dental Ontogeny Sequence of an Extinct Equid: Implications for Equidae Life History and Taphonomy
It is determined that the order of permanent cheek teeth mineralization and eruption of hipparionine horses is m1, m2, (p2, p3), p4, m3, and there are differences in the eruption timing of the p4 and m3 between horses belonging to the Anchitheriinae and Hipparionini compared to equids of the Equus genus.

Deciduous dentition and dental eruption of Hyainailouroidea (Hyaenodonta, “Creodonta,” Placentalia, Mammalia)
The deciduous dental morphology for six hyainailouroids, a clade of hyaenodonts distantly related to Hyaenodon that dominated early Cenozoic meat-eating niches of Afro-Arabia for nearly 20 Ma, is described and the dental eruption sequence of Hyainailsouroidea is reconstructed. Expand
Tooth Eruption Sequences in Cervids and the Effect of Morphology, Life History, and Phylogeny
In ruminants, the different patterns of emergence of permanent teeth seem to be best explained by phylogeny, but the degree of hypsodonty, age of first molar eruption, and life history parameters do not explain the observed sequential differences in eruption patterns. Expand
Deciduous dentition and dental eruption sequence of Bothriogenys fraasi ( Anthracotheriidae , Artiodactyla ) from the Fayum Depression , Egypt
Paleogene anthracotheres are poorly documented from Afro-Arabian localities. This is due, in large part, to the fragmentary nature of the specimens that have been described. However, sediments in theExpand
Palaeobiology of Hyaenodon exiguus (Hyaenodonta, Mammalia) based on morphometric analysis of the bony labyrinth
This study provides the first anatomical description of the bony labyrinth of the extinct European species Hyaenodon exiguus in comparison to selected extant carnivoran taxa discussed from a functional–morphological perspective. Expand
Based on body mass and the general Hyaenodon body plan, it is confidently identified H. leptorhynchus as a cursorial hypercarnivorous predator, hunting prey such as small artiodactyls. Expand
Taxonomic affinities of the enigmatic Prionogale breviceps, early Miocene, Kenya
Understanding of the deciduous dentition of Prionogale allows future analyses to compare homologous morphology, and to explore the environmental factors that shaped carnivorous mammal evolution through the Miocene. Expand
The first hyaenodont from the late Oligocene Nsungwe Formation of Tanzania: Paleoecological insights into the Paleogene-Neogene carnivore transition
The description of Pakakali is important for exploring hyaenodont ontogeny and potential influences of Afro-Arabian tectonic events upon mammalian evolution, providing a deep time perspective on the stability of terrestrial carnivore niches through time. Expand


Differences in the Tooth Eruption Sequence in Hyaenodon (‘Creodonta’: Mammalia) and Implications for the Systematics of the Genus
ABSTRACT Specimens that give new information on the tooth eruption sequence in European Hyaenodon are described. These specimens show a marked difference from the tooth eruption sequence establishedExpand
Implications of the dental eruption sequence in Barbourofelis (Carnivora, Nimravidae) for the function of upper canines and the duration of parental care in sabretoothed carnivores
The eruption sequence of, and patterns of wear to, the dentition of Barbourofelis demonstrate that juveniles were processing meat before the eruption of the deciduous sabres and thus the upper canines were not necessary for feeding, supporting the view that the sabres were preferentially killing devices.

The deciduous lower dentition of Ouranopithecus macedoniensis (Primates, Hominoidea) from the late Miocene deposits of Macedonia, Greece.
The comparison of the lower milk dentition of Ouranopithecus confirms the previous conclusions suggesting that this fossil hominoid shares derived characters with Australopitalcus and Homo. Expand
Delayed eruption of the deciduous upper canine in the sabertoothed carnivore Barbourofelis lovei (Carnivora, Nimravidae)
ABSTRACT In Barbourofelis lovei, from the latest Clarendonian Love Bone Bed, Alachua County, Florida, the eruption of the deciduous upper canine was so delayed that it functioned not as part of theExpand
Dental eruption in afrotherian mammals
Morphological characteristics shared by such physically disparate animals such as elephants and golden moles are not easy to recognize, but are now known to include late eruption of permanent teeth, in addition to vertebral anomalies, testicondy and other features. Expand
Milk tooth morphology of small-sized Hyaenodon (Hyaenodontidae, Mammalia) from the European Oligocene – evidence of a Hyaenodon lineage in Europe
According to this study, Hyaenodon exiguus is more distantly related to North American and Asian species than H. filholi, and thus suggests this species is an Asian immigrant. Expand
Deciduous Dentitions of Eocene Cebochoerid Artiodactyls and Cetartiodactyl Relationships
Deciduous lower premolars (milk teeth) of the Eocene artiodactyl family Cebochoeridae possess accessory denticles and are remarkably similar to both deciduous and adult teeth of the cetacean familyExpand
Deciduous Dentitions of Eocene Cebochoerid Artiodactyls and Cetartiodactyl Relationships
The presence of accessory denticles on some artiodactyl dentitions weakens the morphological support for a monophyletic Artiodactela, suggesting either that whales and cebochoerids may be more closely related than had been thought, or that cebechoerid share a developmental pathway with cetaceans.

Eruption of cheek teeth in insectivora and carnivora.
Eruption sequences of permanent cheek teeth in various insectivores and carnivores were ascertained. The Insectivora shows relatively great variation in eruption sequences, reflecting theExpand
New visions of dental tissue research: Tooth development, chemistry, and structure
New areas of research centered on incremental tooth development, chemical composition, and internal structure have the potential to increase the understanding of developmental biology, including not only changes in the pace of growth and reproduction, but also assessments of diets, migration patterns, environments, and taxonomy.
