Phylogenetic analysis of Middle-Late Miocene apes

Journal of Human Evolution, 2022
Despite intensive study, many aspects of the evolutionary history of great apes and humans (Hominidae) are not well understood. In particular, the phylogenetic relationships of many fossil taxa remain poorly resolved. This study aims to provide an updated hypothesis of phylogenetic relationships for Middle-Late Miocene fossil apes, focusing on those ...

Middle Miocene (∼14 Ma) and Late Miocene (∼6 Ma) Paleogeographic Boundary Conditions

Paleoceanography and Paleoclimatology, 2021
AbstractDuring the Miocene, major global cooling occurred during two intervals: the middle Miocene (∼14–13 Ma) and the late Miocene (∼7‐6 Ma). The Antarctic Ice Sheet expanded substantially at ∼14–13 Ma, and glaciation in the Northern Hemisphere was initiated at ∼7–6 Ma.

First middle Miocene sivaladapid primate from Thailand

Journal of Human Evolution, 2008
Sivaladapids are a group of Asian adapiform primates that were previously documented from deposits dating to the middle Eocene through the late Miocene in Pakistan, India, Myanmar, Thailand, and China. The group is notable for the persistence of three genera, Sivaladapis, Indraloris and Sinoadapis, into the late Miocene.

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

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 ...

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

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 ...

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.

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 ...

Middle Miocene lagomorphs from Paşalar, Turkey

Journal of Human Evolution, 1990
Abstract The Pasalar fauna contains two species of ochotonids: Alloptox anatoliensis and Prolagus oeningensis. The former has Asiatic affinities while the other is a European form. Their occurrence together in Pasalar shows once more the geographically intermediate position of Anatolia between the Asiatic and European bioprovinces.
