All extant toothed whales (Cetacea, Odontoceti) are aquatic mammals with homodont
dentitions. Fossil evidence from the late Oligocene suggests a greater diversity of tooth …

Studies involving anatomical description and taxonomy of fossil odontocetes offer insights
into their evolutionary history and diversity. This study analyses tusk-like teeth in …

Toothed whales (Odontoceti) are adapted for catching prey underwater and possess some
of the most derived feeding specializations of all mammals, including the loss of milk teeth …

Pre-Miocene, stem odontocetes are known for their procumbent incisors and their function
has been the subject of much speculation. Notable among these were Waipatia and several …

The Oligocene Epoch was a time of major radiation of the Odontoceti (echolocating toothed
whales, dolphins). Fossils reveal many odontocete lineages and considerable structural …

A fragment of mandible of an indeterminate squalodontid dolphin (Upper Oligocene or
lowermost Miocene, New Zealand) has 2 anomalous single-rooted teeth intercalated …

The early Miocene is one of the least understood intervals in cetacean evolution. A new
early Miocene dolphin described here, Papahu taitapu, gen. et sp. nov.(family incertae …

A partial odontocete skeleton comprising isolated teeth, forelimb elements, ribs, and
vertebrae is described from the upper Oligocene (Chattian) Jan Juc Marl of Jan Juc, Victoria …

The major increase in cetacean brain size happened in the middle Miocene, about 15
million years ago, and involved the modern oceanic dolphin lineage Delphinoidea. In this …

A late Oligocene marine dolphin–Awamokoa tokarahi gen. et sp. nov.–from the Kokoamu
Greensand (Duntroonian stage, 25.2–27.3 Ma) of Tokarahi, North Otago, New Zealand, is a …
