Middle Miocene closure of the Central American Seaway

Science, 2015
Early closing between oceans The Central American Seaway, which once separated the Panama Arc from South America, may have closed 10 million years earlier than is believed. Montes et al. report that certain minerals of Panamanian provenance began to appear in South America during the Middle Miocene, 15 to ...

Nacholapithecus skeleton from the Middle Miocene of Kenya

Journal of Human Evolution, 2004
An almost entire skeleton of a male individual of Nacholapithecus kerioi (KNM-BG 35250) was discovered from Middle Miocene (approximately 15 Ma) sediments at Nachola, northern Kenya. N. kerioi exhibits a shared derived subnasal morphology with living apes.

ASTROCHRONOLOGY OF LATE MIDDLE MIOCENE MEDITERRANEAN SECTIONS

2004
High-resolution cyclostratigraphy and calcareous plankton astrobiochronology have been obtained from the latest Langhian to the earliest Tortonian of the Mediterranean. The investigated areas (Malta, Tremiti, and Sicily) are located in different geological settings, and the three studied sections show different cyclicity. Direct correlation between the

Endemism in Middle Miocene Caribbean Molluscan Faunas

Science, 1965
The term "middle Miocene Caribbean province" is used for a faunal province that embraced both western Atlantic and eastern Pacific waters. The percentage of endemic species in 13 local faunas in that province is tabulated. In general the largest faunas have the highest percentage of endemic species, but notable exceptions to that generalization are ...

Chronicle of Miocene, Phase III: Middle Miocene Events: ABSTRACT

AAPG Bulletin, 1979
Studies of climate evolution and Cenozoic cooling published in the past several years strengthen our previous paleontologic and stratigraphic models for significant refrigeration accompanied by lowered sea level during the middle Miocene (±15 to 12 m.y.B.P.). Currently, there is general acceptance of a eustatic lowering of sea level during late Miocene

A new Pitheciin primate from the middle Miocene of Argentina

American Journal of Primatology, 1998
We report here a new fossil primate from the middle Miocene of Argentina. The material consists of isolated teeth, mandibular fragments, and a talus. The fossils were collected in the Collón Cura formation at Cañadón del Tordillo in Neuquén Province. An age of 15.71 +/- 0.07 Ma has been reported for the Pilcaniyeu Ignimbrite, which lies just below the ...

Species Recognition in Middle Miocene Hominoids

1993
This chapter addresses the issue of species recognition in fossil samples. The particular example that is examined is the extensive collection of dental and gnathic remains from the middle Miocene locality at Pasalar, Turkey. This site is unusual in that available sedimentological and taphonomic evidence indicate that it was accumulated extremely ...

A Middle Miocene hominoid from Thailand and orangutan origins

Nature, 2003
The origin of orangutans has long been debated. Sivapithecus is considered to be the closest ancestor of orangutans because of its facial-palatal similarities, but its dental characteristics and postcranial skeleton do not confirm this phylogenetic position. Here we report a new Middle Miocene hominoid, cf. Lufengpithecus chiangmuanensis n. sp.

Middle Miocene palaeoenvironments of the Niger Delta

Palaeogeography, Palaeoclimatology, Palaeoecology, 1992
Abstract In order to recognize the palaeoenvironments of the deltaic sequence of the Middle Miocene oil-bearing E2.0 Reservoir in the Kolo Creek field, investigations of sediment grain size, textures, structures, trace fossils, mineralogical composition, diagenetic imprints, palynodebris types, palynomorphs and foraminifera have been carried out on ...

Naticid gastropods from the middle Miocene of western Ukraine

Zootaxa, 2019
The paper covers 11 species of naticid gastropods occurring in the lower Serravallian (Upper Badenian) strata of western Ukraine (Central Paratethys). The studied material (over 1,700 naticids) represents six genera and 11 species, of which eight are new: Cochlis odovychenorum, Cochlis ukrainensis, Tectonatica anistratenkorum, Tectonatica pseudoprietoi,
