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.
Scallop is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters.
Podocnemididae is a family of pleurodire (side-necked) turtles, once widely distributed. Most of its 41 genera and 57 species are now extinct. Seven of its eight surviving species are native to South America: the genus Peltocephalus, with two species, only one of which is extant ; and the genus Podocnemis, with six living species of South American side-necked river turtles and four extinct. There is also one genus native to Madagascar: Erymnochelys, the Madagascan big-headed turtle, whose single species E. madagascariensis.
Chesapecten jeffersonius is the fossilized form of an extinct scallop, which lived in the early Pliocene epoch between four and five million years ago on Virginia's coastal plain. Chesapecten jeffersonius are commonly found in strata exposed along Coastal Plain cliffs along major rivers in southeastern Virginia and eastern North Carolina, and it is the index fossil for the Lower Yorktown Formation.
Argopecten gibbus, the Atlantic calico scallop, is a species of medium-sized edible marine bivalve mollusk in the family Pectinidae, the scallops.
Obinautilus is an extinct genus of shelled cephalopod that has been variously identified as an argonautid octopod or a nautilid. It is known from the Late Oligocene to Pliocene of Japan. The shell is discoidal and very involute, with rapidly expanding and compressed whorls, fine radial ribs, a rounded venter with a shallow furrow, and almost closed umbilicus.
Pecten jacobaeus, the Mediterranean scallop, is a species of scallop, an edible saltwater scallop, a marine bivalve mollusc in the family Pectinidae, the scallops.
Kyptoceras is a small extinct artiodactyl ungulate mammal of the family Protoceratidae, endemic to southeastern North America from the Miocene to Early Pliocene epoch 23.03—3.6 Ma, existing for approximately 19.43 million years. The species name, amatorum, comes in honor of all amateur fossil collectors, including Frank Garcia the amateur who found it and donated it to the Florida Museum of Natural History.
Hesperotestudo is an extinct genus of tortoise native to North and Central America from the Early Miocene to the Late Pleistocene. Species of Hesperotestudo varied widely in size, with a large undescribed specimen from the Late Pleistocene of El Salvador reaching
Mimachlamys varia, also known under common names variegated scallop and black scallop, is a species of small scallop, a marine bivalve mollusk in the family Pectinidae, the scallops. It occurs in the North Sea, the English Channel, the eastern Atlantic Ocean, and the Mediterranean Sea.
Otodus chubutensis, meaning "ear-shaped tooth of Chubut", from Ancient Greek ὠτ and ὀδούς – thus, "ear-shaped tooth", is an extinct species of prehistoric megatoothed sharks in the genus Otodus, that lived during Oligocene, Miocene, and Pliocene, in ~28–5.3 milions years ago. The largest individuals were about 13.5 metres (44 ft) long. This shark is considered a close relative of the famous prehistoric megatoothed shark O. megalodon. However, as is the case with O. megalodon, the classification of this species is disputed.
Ecphora is the common name for a group of extinct predatory marine gastropod mollusks within the family Muricidae, the rocks snails or murexes. The common name is based on the first officially described genus, Ecphora. The entire lineage of these ocenebrinid murexes are descended from the Eocene murex, Tritonopsis. Ecphoras were indigenous to the North American Eastern Seaboard, being found in marine strata from the Late Eocene until their extinction during the Pliocene. Many ecphora species are important index fossils.
Thecachampsa is an extinct genus of gavialoid crocodylian, traditionally regarded as a member of the subfamily Tomistominae. Fossils have been found from the eastern United States in deposits of Miocene age. Those named in the 19th century were distinguished primarily by the shape of their teeth, and have since been combined with T. antiquus. More recently erected species were reassigned from other genera, although their assignment to Thecachampsa has since been questioned.
The Antarctic scallop is a species of bivalve mollusc in the large family of scallops, the Pectinidae. It was thought to be the only species in the genus Adamussium until an extinct Pliocene species was described in 2016. Its exact relationship to other members of the Pectinidae is unclear. It is found in the ice-cold seas surrounding Antarctica, sometimes at great depths.
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.
Ecphora is a genus of extinct predatory ocenebrinid murexes indigenous to the North American Eastern Seaboard from Miocene until their extinction during the Pliocene. The common name for this genus and a group of related genera is "ecphora"(s).
Gigantopecten is a genus of fossil scallops, marine bivalve molluscs in the family Pectinidae, the scallops.
Gigantopecten latissimus is a species of fossil scallop, a marine bivalve mollusk in the family Pectinidae, the scallops. This species lived during the Miocene and the Pliocene. Fossils have been found in the sediments of France and Spain.
Sediliopsis chowanensis is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.
Adamussium is a genus of scallops belonging to the family Pectenidae from the Southern Ocean around Antarctica. There are three known species but only one is extant, the Antarctic scallop. Of the two extinct species A. jonkersi is from the Oligocene deposits on King George Island in the South Shetland Islands and the other, A. necopinatum, was described in 2016 from Pliocene marine deposits in the Vestfold Hills of East Antarctica.
