Tagicetus
''Tagicetus'' is an extinct genus of dolphin belonging to the polyphyletic family Kentriodontidae. Although classified in the subfamily Kentriodontinae by Lambert et al. (2005), recent cladistic analysis places it as closer to extant delphinoids than to ''Kentriodon ''Kentriodon'' is an extinct genus of Odontoceti, toothed whale related to modern-day dolphins.

Kentriodontidae
Kentriodontidae is an extinct family of odontocete whales related to modern dolphins. The Kentriodontidae lived from the Oligocene to the Pliocene before going extinct. Taxonomy Kentriodontids have been variously divided into three or four subfamilies: Kampholophinae, Kentriodontinae, Lophocetinae, and Pithanodelphinae. However, recent cladistic studies have recovered Kentriodontidae as paraphyletic. Pyenson ND Vélez-Juarbe J Gutstein CS Little H Vigil D O’Dea A . 2015.

Kentriodon
''Kentriodon'' is an extinct genus of Odontoceti, toothed whale related to modern-day dolphins. Fossils have been found in North America, Europe and Japan. Several species have been described. Description ''Kentriodon'' was the most diverse of all the Kentriodontidae, kentriodontids, which are represented by seventeen described genera. These were small to medium-sized odontocetes with largely symmetrical skulls, and thought likely to include ancestors of some modern species. ''Kentriodon'' is also the oldest described kentriodontid genus, reported from the Late Oligocene to the Middle Miocene. Kentriodontines ate small fish and other nectonic organisms; they are thought to have been active Animal echolocation, echolocators, and might have formed pods. The diversity, morphology and distribution of fossils appear parallel to some modern species.

Prehistoric Toothed Whales
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
