Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albertocetus Reconstruction Outline
''Albertocetus'' is an extinct genus of primitive odontocete cetacean from early Oligocene (Rupelian) marine deposits in North Carolina, and belonging to the family Xenorophidae. Description ''Albertocetus'' is a relatively small whale, measuring long and weighing approximately . It is distinguished from other xenorophids in having a large lacrimal bone, a steep ascending process of the maxilla, a short but present intertemporal constriction with a sagittal crest, and a tall median ridge on the premaxilla. The teeth were heterodont In anatomy, a heterodont (from Greek, meaning 'different teeth') is an animal which possesses more than a single tooth morphology. In vertebrates, heterodont pertains to animals where teeth are differentiated into different forms. For example, ..., and may have been polydont, because other xenorophids are polydont.

Coronodon Anterolateral At Mace Brown Museum Of Natural History
''Coronodon'' is a genus of toothed mysticetes from the Early Oligocene Ashley Formation of South Carolina. Description It was about the same size as '' Dorudon'', measuring long and weighing . The rostrum of ''Coronodon'' is wide, judging by its straight sides and short mandibular symphysis. Despite being similar to some archaeocetes in having a rostrum that is twisted counterclockwise in anterior view, it differs in having posterior teeth with subequal cusps and an upturned anterior process of the maxilla. ''Coronodon'' differs from other toothed mysticetes in having anterior lower molars labially overlapping posterior lower molars. * Phylogeny ''Coronodon'' falls basally within Mysticeti, being closely related to the unnamed taxon ChM PV 5720 and more primitive than ''" Metasqualodon" symmetricus'', Aetiocetidae, Mammalodontidae, and ''Llanocetus ''Llanocetus'' ( "Llano's whale" ) is a genus of extinct toothed baleen whales from the Late Eocene of Antarctica.

Mysticete
Baleen whales (systematic name Mysticeti), also known as whalebone whales, are a parvorder of carnivorous marine mammals of the infraorder Cetacea (whales, dolphins and porpoises) which use keratinaceous baleen plates (or "whalebone") in their mouths to sieve planktonic creatures from the water. Mysticeti comprises the families Balaenidae (right and bowhead whales), Balaenopteridae (rorquals and the gray whale), and Cetotheriidae (the pygmy right whale). There are currently 16 species of baleen whales. While cetaceans were historically thought to have descended from mesonychids, molecular evidence instead supports them as a clade of even-toed ungulates (Artiodactyla). Baleen whales split from toothed whales (Odontoceti) around 34 million years ago. Baleen whales range in size from the and pygmy right whale to the and blue whale, the largest known animal to have ever existed. They are sexually dimorphic. Baleen whales can have streamlined or large bodies, depending on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ankylorhiza Tiedemani Life Reconstruction By PaleoGeek
''Ankylorhiza'' (meaning "fused roots"; in reference to the type of dentition seen in early toothed whales) is an extinct genus of toothed whale that lived in what is now the United States during the Oligocene epoch, between 29 and 23.5 million years ago. The type and only known species is ''A. tiedemani'', though two fossil skeletons may represent an additional, second species within the genus. ''Ankylorhiza'' was about long, with a long, robust skull bearing conical teeth that were angled forwards at the tip of the snout. ''Ankylorhiza'' is the largest known Oligocene toothed whale and is one of the most completely known early members of this group, with characteristics intermediate between basal and derived cetaceans. The taxon would have had powerful jaw musculature and probably fed on large prey by seizing it and puncturing it with its robust teeth. The animal likely occupied a fast-swimming predator niche similar to that of living orcas. Discovery and naming The holo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odontocete
The toothed whales (also called odontocetes, systematic name Odontoceti) are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and sperm whales. Seventy-three species of toothed whales are described. They are one of two living groups of cetaceans, the other being the baleen whales (Mysticeti), which have baleen instead of teeth. The two groups are thought to have diverged around 34 million years ago (mya). Toothed whales range in size from the and vaquita to the and sperm whale. Several species of odontocetes exhibit sexual dimorphism, in that there are size or other morphological differences between females and males. They have streamlined bodies and two limbs that are modified into flippers. Some can travel at up to 20 knots. Odontocetes have conical teeth designed for catching fish or squid. They have well-developed hearing, that is well adapted for both air and water, so much so that some can sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
