Angiosperm pollen grains from the Cuayuca Formation (Late Eocene to Early Oligocene), Puebla, Mexico [PDF]
Systematic descriptions and illustrations of the best preserved angiosperm pollen grains (Monocotyledonae or Liliopsida: n= 7 and Dicotyledonae or Magnoliopsida: n= 41) recovered from Cuayuca Formation (late Eocene-early Oligocene), Puebla State ...

New fossil taxa of Monophlebidae (Sternorrhyncha: Coccoidea) from Baltic amber
The family Monophlebidae is distributed worldwide and is classified as one of the "archaeococcoid" families. After almost 160 years since Germar & Berendt (1856) described the first and so far only fossil monophlebid species, Monophlebus irregularis, two

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

A Predictive Algorithm For Wetlands In Deep Time Paleoclimate Models [PDF]
Methane is a powerful greenhouse gas produced in wetland environments via microbial action in anaerobic conditions. If the location and extent of wetlands are unknown, such as for the Earth many millions of years in the past, a model of wetland fraction ...

The relationship between form and function of the carnivore mandible
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Geometric morphometrics of endophytic oviposition traces of Odonata (Eocene, Argentina) [PDF]
The insertion of the Odonata ovipositor in the plant tissue generates a scar that surrounds the eggs (trace). In insects, individual egg traces are known to vary in size, but their variation in individual shape is mostly unknown.

Searching for the Terrestrial Paleocene/Eocene Boundary at the Canadian High Arctic: A Carbon Isotope Study [PDF]
The Paleocene Eocene Thermal Maximum (PETM) is a rare climatic event in the history of the Earth, which marks the abrupt transition from the Paleocene to Eocene of the Cenozoic era with a rapid increase in global surface temperatures of up to 5-8C ...
