The study of rodent fossils allows to determine the climate of the south of the Iberian Peninsula six million years ago

29.11.2007
How did the rodents which inhabited the south of the Iberian Peninsula live six million years ago?

The researcher of the UGR Raef Minwer-Barakat has attempted to answer this question through his doctoral thesis "Rodents and insectivorous of Upper Turoliense and the Pliocene of the central section of the Guadix basin", supervised by doctors Elvira Martín and César Viseras, of the Dept. of Stratigraphy and Palaeontology of the University of Granada.

His studied has concluded with the discovering of three new species of rodents and insectivores (Micromys caesaris, Blarinoides aliciae and Archaeodesmana elvirae) and the finding, for the first time in the region, of nine more species.

Minwer-Barakat chose the Guadix basin to develop his study due to the excellent conditions of the area and its abundance of fossils of small mammals. Although there were previous studied on rodents in this region, no-one had had carried out such a complete study were on the fauna of fossil insectivores.

This research work is based on the analysis of the dental structures of rodents, key elements in Palaeontology to differentiate between two species as they become fossilized very easily.

The research work, backed by the UGR, has also managed to determine that the Myocricetodon jaegeri, a species of gerbil whose presence has been documented at the end of the Miocene from Africa, a theory which had not been confirmed yet.

The climate
Raef Minwer-Barakat´s thesis has allowed to carry out a radiography of the climate evolution in the south of the Iberian Peninsula in the analyzed periods. In the Upper Turoliense (from 6 to 5.3 million years ago) the climate was almost desert-like, with scarce vegetation, and during the Rusciniense and at the beginning of the Villafranquiense (from 5.3 to 3 million years ago) the conditions became warmer and damper. At the end of the lower Villafranquiense and during the middle Villafranquiense Granada’s climate became much colder and drier, with a predominance of open herbaceous environments.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
