Tertiary conglomerates of the North border of Sierra de Cameros
Cuadernos de Investigación Geográfica, 2013 The present paper is a study of the age of the siliceous conglomerates not consolidates situated in the Northern Sierra de Cameros. The age of these rocks are: Upper Oligocene (Chattian or older) the oldest; middle Miocene (Vindobonian) the intermediate;

The Anatomical Record, EarlyView.Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Understanding the Middle Miocene Climatic Optimum: Evaluation of Deuterium Values (δD) Related to Precipitation and Temperature [PDF]
, 2013 The Middle Miocene Climate Optimum was a unique warming period in the Earth’s geologic history, when a high global mean annual temperature was accompanied by a relatively low global CO2 concentration. Hydrogen isotopic signals (specifically molecular δD,

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans
The Anatomical Record, EarlyView.Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

The Middle Miocene climate as modelled in an atmosphere-ocean-biosphere model [PDF]
Climate of the Past, 2011 We present simulations with a coupled atmosphere-ocean-biosphere model for the Middle Miocene 15 million years ago. The model is insofar more consistent than previous models because it captures the essential interactions between ocean and atmosphere and ...

Two Crusafontina (Mammalia, Insectivora) fossils from the Miocene of the Transdanubian Central Range (Hungary) [PDF]
, 2008 Two isolated teeth of Anourosoricini shrews, Crusafontina (Mammalia, Insectivora, Soricidae) are present in this paper. A complete left maxillary molar was found in the Sarmatian (Middle Miocene) locality of Várpalota Lignite Mine, Pit III.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence
Biological Reviews, EarlyView.ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Kangaroo morphometrics: how Miocene kangaroos can inform us about palaeoenvironments and how giant Pleistocene kangaroos managed to locomote [PDF]
, 2015 Kangaroos are known today for their spectacular hopping locomotion, but kangaroo diversity in the past tells a different story. Some kinds of extinct kangaroos (sthenurines) grew so large that hopping would seem to be unlikely.
