Miocene paleoenvironments and paleosol pH proxies.
… performed at Coffee Ranch, the site of a late Miocene (6.6 Ma) bonebed in the Texas Panhandle. Using sedimentology, stratigraphy, and paleopedology, the depositional environments at Coffee Ranch were reconstructed as a fluvial system with seasonally-variable discharge, alluvial paleosols with …

Pressuremeter testing in miocene stiff clays
… place. This study focuses on in situ testing in Miocene stiff clays using an advanced nine strain arm self-boring pressuremeter (SBPM). This device was used to test the soils in both a self-boring and a simpler, non-boring mode (pre-bored or PBPM tests). The Miocene stiff clay was unique in that …

The oligo-miocene sediments of the Maltese Islands
The Maltese Islands are situated at the south-western end of the Malta-Ragusa Rise, an area characterised by high gravity anomaly values and a ridge-like bathymetrical profile. The Islands lie 50-80km. south of Sicily and 282km. away from the north African coastline.The sedimentary sequence is …

Middle Miocene carbon cycle dynamics: A multi-proxy approach
… sheets in Antarctica happened during the middle Miocene, about 14 million years ago (Flower and Kennett, 1995; Zachos et al., 2001). The middle Miocene therefore represents one of the distinct phases of rapid change in the transition from the “greenhouse” of the Cretaceous to the “icehouse” of …

Eocene to Miocene geology of southwest Viti Levu, Fiji
… unconformity by the Upper Oligocene to Middle Miocene Wainimala Group which includes volcaniclastic turbidites, hemipelagic carbonates and vitric tuffs deposited in the Sigatoka sedimentary basin, and further south volcaniclastic rudites, intrusive/extrusive dacites and andesites, and minor …

Bilateral Asymmetry in Incisors: Implications for Miocene Hominoid Species Diagnosis
… ASYMMETRY IN INCISORS: IMPLICATIONS FOR MIOCENE HOMINOID SPECIES DIAGNOSIS MAJOR PROFESSOR: Dr. Robert S. Corruccini The primary purpose of this dissertation is to show how knowledge of variation and asymmetry in incisor antimeric pairs of living great ape genera can be utilized as a …

Sedimentology of Marine Vertebrate Burial in the Miocene Pisco Fm., Peru
<p>The Miocene Pisco Basin of Peru is known for abundant, well-preserved marine vertebrate fossils (Esperante et al. 2000). Cetacean fossils are particularly abundant—so much so that we were able to locate 10 outcrops containing specimens in cross section, which allowed us to do detailed …

Depositional Environments of the Miocene Esmeralda Formation, Stewart Basin, Stewart Valley, Nevada
… specific depositional environments of the Miocene Esmeralda Formation in Stewart Basin (Stewart Valley), Mineral County, Nevada. Previous workers have concentrated on paleontological aspects of the basin and have described in detail the molluscs, mammals and macroflora. Less work has been …

Miocene core complex development and coeval supradetachment basin evolution of Paros, Greece
This study evaluates the tectonosedimentary evolution of Paros, Greece using apatite and zircon (U-Th)/He dating to assess the currently accepted kinematic history and resolve controversy about the formation of and sources to the Paros supradetachment basin. Overdispersed and improbable results in …

Paleoclimate and paleoecology of Miocene Eastern African primate habitats : a multiproxy approach.
Reconstructing Miocene climate and ecosystem in eastern Africa is essential for understanding the environmental and geological contexts in which early primates evolved. Particularly, correlations between leaf size, shape, temperature, and precipitation have become a widely used tool for …

Mammal and bird trackways in the Miocene Horse Spring Formation, Clark County, Nevada
The Thumb Member of the Miocene Horse Spring Formation contains a vertebrate track assemblage of mammal (camel and carnivore) and avian footprints. Camelid tracks identified are Lamaichnum alfi, Lamaichnum macropodum, and Lamaichnum etoromorphum. Carnivore tracks include canid tracks (Canipeda sp.) …

Miocene herpetofaunas from the central Gulf Coast USA: their paleoecology, biogeography, and biostratigraphy
… The herpetofaunal composition of Fort Polk and Miocene east Texas localities is similar enough to Great Plains localities that they are all considered to be one biogeographical province during the Barstovian. The use of ternary diagrams, ratios of herpetological elements to kg matrix screened, …

Protein Preservation in Fossil Whale Bones of the Miocene/Pliocene Pisco Formation, Peru
Fossil remains have recently been the focus of considerable attention due to several independent reports of protein and soft-tissue preservation in ancient biological remains. The fossil whales from the Pisco Formation in Peru were previously reported to be very well preserved. A considerable …
