Cerorhinca is a genus of auk containing the rhinoceros auklet and several fossil species.
The genus Cerorhinca evolved in the North Pacific during the Miocene. Fossils have been found as far south as Baja California. While previously only known from the Pacific region, an unnamed species has been discovered from the Pliocene of North Carolina, suggesting the genus had a much wider distribution in the past. [1]
Eschrichtiidae or the gray whales is a family of baleen whale with a single extant species, the gray whale, as well as three described fossil genera: Archaeschrichtius and Eschrichtioides from the Miocene and Pliocene of Italy respectively, and Gricetoides from the Pliocene of North Carolina. More recent phylogenetic studies have found this family to be invalid, with its members nesting inside the Balaenopteridae. The names of the extant genus and the family honours Danish zoologist Daniel Eschricht.
Puffins are any of three species of small alcids (auks) in the bird genus Fratercula. These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin, are found in the North Pacific Ocean, while the Atlantic puffin is found in the North Atlantic Ocean.
An auk or alcid is a bird of the family Alcidae in the order Charadriiformes. The alcid family includes the murres, guillemots, auklets, puffins, and murrelets. The family contains 25 extant or recently extinct species that are divided into 11 genera.
Loons or divers are a group of aquatic birds found in much of North America and northern Eurasia. All living species of loons are members of the genus Gavia, family Gaviidae and order Gaviiformes.
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the International Ornithologists' Union (IOU) adopted a consensus taxonomy of seven genera. The great cormorant and the common shag are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly.
Balaenoptera is a genus of rorquals containing eight extant species. Balaenoptera comprises all but two of the extant species in its family ; the genus is currently polyphyletic, with the two aforementioned species being phylogenetically nested within it.
The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America, migrating to more southernly coasts in winter, and as resident birds in the Hawaiian Islands. Alone in the Southern Hemisphere, a self-sustaining feral population derived from introduced Canada geese is also found in New Zealand.
Lysimachia is a genus consisting of 193 accepted species of flowering plants traditionally classified in the family Primulaceae. Based on a molecular phylogenetic study it was transferred to the family Myrsinaceae, before this family was later merged into the Primulaceae.
Ostriches are large flightless birds. They are the heaviest and largest living birds, with adult common ostriches weighing anywhere between 63.5-145 kilograms and laying the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. They are farmed worldwide, with significant industries in the Philippines and in Namibia. Ostrich leather is a lucrative commodity, and the large feathers are used as plumes for the decoration of ceremonial headgear. Ostrich eggs have been used by humans for millennia.
The rhinoceros auklet is a seabird and a close relative of the puffins. It is the only extant species of the genus Cerorhinca. Given its close relationship with the puffins, the common name rhinoceros puffin has been proposed for the species.
Teucrium is a cosmopolitan genus of flowering plants in the family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals.
The great albatrosses are seabirds in the genus Diomedea in the albatross family. The genus Diomedea formerly included all albatrosses except the sooty albatrosses, but in 1996 the genus was split, with the mollymawks and the North Pacific albatrosses both being elevated to separate genera.
Oncorhynchus rastrosus also known as the saber-toothed salmon, or spike-toothed salmon is an extinct species of salmon that lived along the Pacific coast of North America and Japan. They first appeared in the late Miocene in California, then died out some time during the Early Pliocene.
Ontocetus is an extinct genus of walrus, an aquatic carnivoran of the family Odobenidae, endemic to coastal regions of the southern North Sea and the southeastern coastal regions of the U.S. during the Miocene-Pleistocene. It lived from 13.6 mya—300,000 years ago, existing for approximately 13.3 million years.
Metaxytherium is an extinct genus of dugong that lived from the Oligocene until the end of the Pliocene. Fossil remains have been found in Africa, Europe, North America and South America. Generally marine seagrass specialists, they inhabited the warm and shallow waters of the Paratethys, Mediterranean, Caribbean Sea and Pacific coastline. American species of Metaxytherium are considered to be ancestral to the North Pacific family Hydrodamalinae, which includes the giant Steller's Sea Cow.
Pseudodontornis is a rather disputed genus of the prehistoric pseudotooth birds. The pseudotooth birds or pelagornithids were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty. Up to five species are commonly recognized in this genus.
Pterodromoides is an extinct genus of fulmarine petrel dating from the Late Miocene. It contains a single species, P. minoricensis. Its fossil remains were first discovered at the Punta Nati palaeontological site on the island of Menorca in the Balearic archipelago of the western Mediterranean. An additional specimen from North Carolina, USA has also been referred to this species, suggesting it lived across the North Atlantic. It was described in 2001, with the authors justifying the creation of a new genus by the large orbitonasal opening and characters of the postcranial skeleton, despite the similarity of the cranial osteology to that of Pagodroma.
Balaenula is an extinct genus of baleen whale species which lived during the Pliocene epoch of Europe and possibly North America. Balaenula is a small whale measuring within the range of 6–8 metres (20–26 ft) in length.
Albicetus is a genus of stem-sperm whales that lived during the Miocene Epoch, around 15 million years ago, and was discovered in Santa Barbara, California in 1909. It was categorized for decades as belonging to a group of extinct walruses erroneously thought to be sperm whales. It was named Albicetus, meaning "white whale", is a reference to the leviathan in Herman Melville's classic 1851 novel Moby-Dick.
Gavia howardae is an extinct species of loon from the Piacenzian age from United States. Fossils of this bird were initially found in 1947 by Clifford Kennell in the San Diego Formation, California and were given a name in 1953 by Pierce Brodkorb. These first specimens consisted of humeri bones, which Brodkorb indicated based on the distal end of the humerus were a smaller species of the genus Gavia, with a possible relationship with the pacific loon. More specimens were collected from the same deposits covering the entirety of the wing, some more complete than others. Chandler (1990) described and published these new materials and found G. howardae to be related to the red-throated loon instead. Additional material has been recovered from the Yorktown Formation, North Carolina where in addition more wing bones, there were also remains of the leg and shoulder regions. Based on the overall size of the remains, G. howardae was on average smaller than the red-throated loon, and one of the smallest species of Neogene loons from North America.
