Eumaiochoerus is an extinct genus of even-toed ungulates that existed during the Miocene in Italy. [1] [2]
Eumaiochoerus had a short snout, spatulate upper incisors and small, chisel-shaped lower tusks.
Fossils of Eumaiochoerus were found in Baccinello and Montebamboli in Italy, which at the time of its existence would have been an island chain. Eumaiochoerus does show characteristics of an insular mammal, being much smaller in size than its mainland relative Microstonyx . [3]
The snowy egret is a small white heron. The genus name comes from Provençal French for the little egret, aigrette, which is a diminutive of aigron, 'heron'. The species name thula is the Araucano term for the black-necked swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.
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.
Caiman is a genus of caimans within the alligatorid subfamily Caimaninae. They inhabit Central and South America. They are relatively small sized crocodilians, with all species reaching lengths of only a couple of meters and weighing 6 to 40 kg on average.
Carcharhinus is the type genus of the family Carcharhinidae, the requiem sharks. One of 12 genera in its family, it contains over half of the species therein. It contains 35 extant and eight extinct species to date, with likely more species yet to be described.
The Deseadan age is a period of geologic time within the Oligocene epoch of the Paleogene to the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification of South America. It follows the Tinguirirican and precedes the Colhuehuapian age.
The Laventan age is a period of geologic time within the Middle Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Colloncuran and precedes the Mayoan age.
Habroichthys is an extinct genus of prehistoric bony fish that lived during the early Ladinian stage of the Middle Triassic epoch, 242 to 232 million years ago. It has been found in Austria, China, Italy, Slovenia, and Switzerland. It was a small fish measuring 26 cm (10 in) long.
Madysaurus is an extinct genus of cynodonts which existed in Kyrgyzstan. It was first named by Leonid Petrovich Tatarinov in 2005. Madysaurus is known from the Madygen Formation, a Triassic Lagerstätte that also includes well-preserved remains of insects and small reptiles like Sharovipteryx and Longisquama. Madysaurus is one of the most primitive cynodonts and is placed in its own family, Madysauridae.
The Kokoamu Greensand is a geological formation found in New Zealand. It is a fossil-bearing, late Oligocene, greensand rock unit of the eastern South Island, especially the Waitaki District of North Otago and the southern Canterbury region. The formation was named by geologist Maxwell Gage in the 1950s. In North Otago it underlies the thicker and harder Otekaike Limestone. The formation gets its green colour from the mineral glauconite which forms slowly on the ocean floor.
Tusciziphius is an extinct genus of ziphiid cetaceans. The distribution includes the Miocene of Portugal and Spain, and the Pliocene of Italy and the United States. Two species are known: T. atlanticus and T. crispus. The type specimen of T. crispus is IGF 1534, 1536, 1537, 1569, 1570, 1572, 1594 V, a partial skeleton. Its type locality is Case il Poggio, which is in a Zanclean coastal sandstone/claystone in Italy.
The Yaguarasaurinae are a subfamily of mosasaurs, a diverse group of Late Cretaceous marine squamates. Members of the subfamily are informally and collectively known as "yaguarasaurines" and have been recovered from North and South America and Europe. Three genera, Yaguarasaurus, Russellosaurus and Romeosaurus are known. Yaguarasaurus and Russellosaurus were previously considered part of the Tethysaurinae until they were grouped with Romeosaurus as yaguarasaurines.
Eschrichtioides is an extinct genus of baleen whale known from the early Pliocene of northern Italy. Its type species, E. gastaldii, had a complex taxonomic history, starting as a cetothere, then as an extinct member of Balaenoptera, before being finally recognized as a relative of the gray whale.
Micromomyidae (Micromomids) is a family of extinct plesiadapiform mammals that include some of the earliest known primates. The family includes five genera that lived from the Paleocene epoch into the early Eocene epoch.
Cainochoerus was an extinct genus of even-toed ungulates which lived during the Miocene and Pliocene in Africa. Fossils have been found in Kenya, Ethiopia and South Africa.
The Hiló Formation is a geological formation of the Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The predominantly shale formation dates to the Middle Cretaceous period; Late Albian to Early Cenomanian epochs and has a measured thickness at its type section of 470 metres (1,540 ft). The fossiliferous formation has provided a great abundance of ammonites and other marine species.
Boreostemma is an extinct genus of glyptodonts from northern South America. Fossils assigned to the genus were first described as belonging to Asterostemma from southern South America, but have been placed in the new genus Boreostemma by Carlini et al. in 2008. The type species is B. pliocena. Fossils of Boreostemma have been found in the Honda Group of Colombia, in Peru and Venezuela.
Miocochilius is an extinct genus of small notoungulate mammals (typotheres) native to South America. The genus lived during the Middle Miocene epoch. The genus contains two described species, the type species M. anomopodus described in 1953 by Ruben Arthur Stirton and M. federicoi, described and included in the genus by Darin A. Croft.
Tyrrhenotragus is an extinct genus of bovid that lived in the Late Miocene of Italy. It contains a single species, Tyrrhenotragus gracillimus. Fossils were of Late Vallesian and Early Turolian age and have been found in Baccinello, which at the time of its existence was an island. T. gracillimus has features that are suggestive of an insular animal adapted to island existence.
