Hyoliths are animals with small conical shells, known as fossils from the Palaeozoic era. They are at least considered as lophotrochozoan, and possibly being lophophorates, a group which includes the brachiopods, while others consider them as being basal lophotrochozoans, or even molluscs.
Miacis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
The evolution of the molluscs is the way in which the Mollusca, one of the largest groups of invertebrate animals, evolved. This phylum includes gastropods, bivalves, scaphopods, cephalopods, and several other groups. The fossil record of mollusks is relatively complete, and they are well represented in most fossil-bearing marine strata. Very early organisms which have dubiously been compared to molluscs include Kimberella and Odontogriphus.
Microsauria is an extinct, possibly polyphyletic order of amphibians from the late Carboniferous and early Permian periods. It is the most diverse and species-rich group of lepospondyls. Recently, Microsauria has been considered paraphyletic, as several other non-microsaur lepospondyl groups such as Lysorophia seem to be nested in it. Microsauria is now commonly used as a collective term for the grade of lepospondyls that were originally classified as members of Microsauria.
Ceratodus is an extinct genus lungfish. It has been described as a "catch all", and a "form genus" used to refer to the remains of a variety of lungfish belonging to the extinct family Ceratodontidae. Fossil evidence dates back to the Early Triassic. A wide range of fossil species from different time periods have been found around the world in places such as the United States, Argentina, Greenland, England, Germany, Egypt, Madagascar, China, and Australia. Ceratodus is believed to have become extinct sometime around the beginning of the Eocene Epoch.
Vulpavus is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Miocyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to late Eocene.
Prodaphaenus is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America during the middle Eocene.
Uintacyon is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene.
Vassacyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America and Europe from late Paleocene to early Eocene. It is considered the largest of the early Eocene mammals.
Xinyuictis is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Asia from early to late Eocene.
Messelogale is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Europe during middle Eocene.
Hapsidopareion is an extinct genus of microsaur belonging to the family Hapsidopareiidae. Fossils have been found in the early Permian of Oklahoma.
Gracilocyon is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America and Europe from late Paleocene to early Eocene.
Orthotheca is a genus of sessile bottom-dwelling hyolith.
Dawsonicyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from early to middle Eocene. Fossils of type species Dawsonicyon isami are known from the ‘Bridger B’, site of Black’s Fork member of the Bridger Formation in Wyoming, and includes an almost complete skeleton.
The orthothecids are one of the two hyolith orders.
Dormaalocyon is an extinct genus of placental mammals from clade Carnivoraformes, that lived in Europe during early Eocene. Type species, Dormaalocyon latouri was discovered when fossils were unearthed in the village of Dormaal, near Zoutleeuw, in the Belgian province of Flemish Brabant.
The Ash Hollow Formation of the Ogallala Group is a geological formation found in Nebraska and South Dakota. It preserves fossils dating back to the Neogene period. It was named after Ash Hollow, Nebraska and can be seen in Ash Hollow State Historical Park. Ashfall Fossil Beds State Historical Park is within this formation.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2016.
