A Fossilized Giant Rhinocerotoid Bone Calls into Question the Isolation of Anatolia, 25 Million Years Ago

Contrary to generally accepted belief, Anatolia1 was not geographically isolated 25 million years ago (during the Oligocene epoch): this has just been demonstrated by researchers from the Laboratoire des Mécanismes et Transferts en Géologie (LMTG) (CNRS/ University of Toulouse 3/IRD) and the Paléobiodiversité et paléoenvironnements laboratory (CNRS/Muséum national d’histoire naturelle/University of Paris 6).

These results were obtained thanks to analyses of the first fossilized giant rhinocerotoid bone discovered in 20022 in an Anatolian deposit during a Franco-Turkish paleontology expedition funded by the ECLIPSE INSU-CNRS program. The presence of this bone in Anatolia, with the remains of associated fauna, are indicative of animal migrations between Europe and Asia. The results, published online in the March 2008 issue of the Zoological Journal of the Linnean Society, thus call into question the isolation of Anatolia, which until now was considered to have been an archipelago.

This is the first time that a fossilized giant rhinocerotoid bone dating from the Oligocene epoch (a period corresponding to intense tectonic movements around the Mediterranean Sea) has been found in Anatolia. Discovered in 2002 during a Franco-Turkish paleontology expedition in the region of ÇankiriÇorum (Central Anatolia, Turkey), the bone fragment3 from the forearm (radius) described by the scientists measures 1.20 meters long and probably belonged to a very large male (about 5 meters to the shoulder), attributed to the Paraceratherium genus. These herbivorous animals, also called baluchitheres or indricotheres, are considered to have been the largest terrestrial mammals that ever existed, equal in size to the largest mammoths (with a height to the shoulder estimated to be 5 meters or more, and a body weight of 15 to 20 tons).

As well as this specimen of Paraceratherium, known to have existed notably in Pakistan, China, Mongolia and Kazakhstan, the remains of ruminants and rodents were also found in the deposit. They enabled dating of the specimen to about 25 million years, and also exhibited close affinities with contemporary fauna in Asia and/or Europe. This observation is particularly surprising in that Anatolia was until now considered to have been an archipelago at that time, separated from both Europe and Asia by what is referred to as the Paratethys Sea; the Black, Caspian and Aral seas are today the only remaining vestiges of this body of water. The discovery thus proves the existence of terrestrial communication and close links at that period between Europe (including France) and Asia (China, Mongolia, Pakistan). Thus, during the Oligocene epoch, Anatolia was not isolated by the sea and was at least an isthmus: animals could therefore cross on dry land from continental Asia to Anatolia.

On the other hand, this discovery also tends to confirm that there was indeed a separation from Africa, as to date no species of African affinity has been found in the Oligocene soils of Anatolia.

1 A peninsula situated at the western tip of Asia, it now corresponds to the Asiatic part of Turkey (96% of the total Turkish landmass, the remaining 4% being situated in Thrace).

2 In the region of Çankiri-Çorum (Central Anatolia, Turkey).

3 This is similar in size to the largest radius from a baluchithere known to date, a specimen discovered in Mongolia during the 1930s in strata dating from the same period (approximately 25 million years).

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
