Bairdemys
''Bairdemys'' is an extinct genus of side-necked turtles in the family Podocnemididae. The genus existed from the Late Oligocene to Late Miocene and its fossils have been found in South Carolina, Puerto Rico, Panama and Venezuela. The genus was described in 2002 by Gaffney & Wood and the type species is ''B. hartsteini''. Description The first species in the genus described was ''B. venezuelensis'' as '' Podocnemis venezuelensis'' by Wood and Díaz de Gamero in 1971.Gaffney et al., 2008 Species * ''B. hartsteini'' * ''B. healeyorum'' * ''B. sanchezi'' * ''B. thalassica'' * ''B. venezuelensis'' * ''B. winklerae'' Phylogeny ''Bairdemys'' was placed phylogenetically by Ferreira et al. in 2015.Ferreira et al., 2015, p.10 Distribution Fossils of ''Bairdemys'' have been found in:''Bairdemys'' at ...

Laventan
The Laventan ( es, Laventense) age is a period of geologic time (13.8 to 11.8 Ma) 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.Madden et al., 1997 Etymology The age is named after the Miocene Lagerstätte La Venta, where a rich biodiversity from the Middle Miocene has been recovered from the Honda Group.

Chasicoan
The Chasicoan ( es, Chasiquense or es, Chasicoense) age is a period of geologic time from 10–9 Ma within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Mayoan and precedes the Huayquerian age. at Fossilworks

Podocnemididae
Podocnemididae is a family of pleurodire (side-necked) turtles, once widely distributed. Most of its 20 genera and 30 species are now extinct. Seven of its eight surviving species are native to South America: the genus ''Peltocephalus'', with only one species (''P. dumerilianus'', the big-headed Amazon River turtle); and the genus ''Podocnemis'', with six living species of South American side-necked river turtles. There is also one genus native to Madagascar: ''Erymnochelys'', the Madagascan big-headed turtle, whose single species ''E. madagascariensis''. Like other pleurodire turtles, podocs have a "side-necked" defensive posture, turning the head sideways to hide it under the shell. Another characteristic of pleurodires is that the pelvis is fused to the shell which prevents pelvic motion, making it difficult to walk on land. Podocnemididae turtles live in aquatic environments and have shells streamlined to aid in swimming. Taxonomy and systematics According to Ferreira et ...

Castillo Formation, Venezuela
The Castillo Formation is an Early Miocene (Burdigalian, Colhuehuapian to Santacrucian in the SALMA classification) geologic formation in the Falcón Basin of Venezuela. The formation unconformably overlies the Matatere, Misoa, El Paují and Jarillal Formations.Urbani & Mendi, 2010, p.17 The Castillo Formation is overlain by Quaternary alluvium and in places by the Capadare Formation.Urbani & Mendi, 2010, p.19 The formation, deposited in a calm near-shore lagoonal brackish environment, with possibly fluvial influence, has provided a rich assemblage of fossil crocodylians, turtles, giant sloths and various types of fish. Description The Castillo Formation crops out cover a wide semicircular area that extends through the northwestern Venezuelan states of Falcón and Lara. During Oligocene to Miocene times, the formation formed the northwest to southeast edge of the Falcón Basin.Solórzano et al., 2018a, p.3 The formation, with a minimum thickness of ,Rincón et al., 2014, ...

Alajuela Formation
The Alajuela Formation, originally Alhajuela Formation (Tau),Geologic Map, 1980 is a Miocene, Late Miocene (Tortonian, Hemphillian, Early Hemphillian or Clarendonian, Latest Clarendonian in the North American land mammal age, NALMA classification) Formation (geology), geologic formation in the Panama Canal Zone of central Panama. The formation overlies the Caimito Formation and comprises sandstones, limestones and conglomerate (geology), conglomerates deposited in a tidal-dominated estuary, estuarine to shallow marine depositional environment, environment. The formation crops out in a small area along the southern and western shores of Lake Alajuela, of which it derives its name, and preserves a rich fossil faunal assemblage of mammals, fish (among which fossil teeth of megalodon), invertebrates and flora. The fauna is of paleontological significance as an insight into the ecosystem of Central America preceding the Great American Biotic Interchange (GABI). Description The Alaj ...

Urumaco Formation
The Urumaco Formation is a formation in Venezuela that includes deposits from the Late Miocene. It is the site of several "giant forms": the turtles, crocodiles, sloths and rodents of Urumaco are among the largest of their groups. Location The Urumaco formation is located in the Urumaco region in the Caribbean coastal Falcón state. The deposits date from 10 to 5.3 million years ago and the Urumaco formation was deposited in an area with large rivers, swamps, estuaries, lagoons and shallow coastal seas. These conditions in the Late Miocene contrast strongly with the current dry environment in the area today. Fauna Cartilaginous fish There are 21 known species of cartilaginous fishes from the Urumaco Formation, belonging to the orders Lamniformes, Carcharhiniformes, Myliobatiformes and Rajiformes. ''Carcharhinus caquetius'' is an endemic species of predator shark from Urumaco. A large number of well-preserved fossils of the sawfish ''Pristis rostra'' have been found in th ...

Pleurodira
The Pleurodira are one of the two living suborders of turtles, the other being the Cryptodira. The division between these two suborders represents a very deep evolutionary divide between two very different types of turtles. The physical differences between them, although anatomical and largely internal, are nonetheless significant, and the zoogeographic implications of them are substantial. The Pleurodira are known more commonly as the side-necked turtles and the name Pleurodira quite literally translates to side neck, whereas the Cryptodira are known as hidden-necked turtles. The Pleurodira turtles are currently restricted to freshwater habitats in the Southern Hemisphere, largely to Australia, South America, and Africa. Within the Pleurodira, three living families are represented: Chelidae, also known as the Austro-South American side-necked turtles, the Pelomedusidae, also known as the African mud terrapins, and the Podocnemididae, also known as the American side-neck river tur ...
