In The Morocco, found the ancient city of underground animals

21 Sep

ancientAbove 240 million years ago, unknown creatures dug up an entire underground city in Morocco.This is the oldest example of such a structure at low latitudes. Globally, the leader of South Africa are burrows constructed by 5 million years earlier. Perhaps the authors of both structures were similar establishment. “Imagine a sturdy four-legged animal with a rather short body, small tail and short neck – said study author Sebastian Voigt of the Geological Institute of Technology, University of Freiberg (Germany). – The length of the trunk was about 20-25 cm We have to admit that the beast had a five-strong fingers with claws adapted for use in moderately soft ground.
Burrows are located in the red sediments of the tectonic basin in the central part of Argan Morocco. The construction consists of several entrances, exits, tunnels and chambers. “This structure has no equivalent of either the fossil or among the dwellings of modern vertebrates – said Mr. Voigt. – It is extremely difficult, and her double twisting passages were not observed anywhere else. ”
The researchers concluded that the underworld was a refuge from predators. Dinosaurs at the time was not yet, but there were carried out massive and rapid “crocodiles” with long legs. Company they were close relatives of modern lizards, snakes and tuatara.
Geology of the place, as well as the normal design hints at what animals were hiding under the ground of bad weather. “In the Triassic the region, I think, was a large semi-desert, situated at some distance from the sea – says Mr. Voigt. – Rivers appeared only in the rainy season, and the channel was shallow. The banks covered the rather thin vegetation. It was hot during the day, at night – cold. ”
Smooth floor of tunnels said that they actively used. Most likely, residents were selected at night – to profit by plants, roots and insects.
Burrows constructed by individual animals (eg fish) are beginning to appear in the Early Paleozoic. In other words, this practice – almost as old as complex biological forms. Mr. Voigt suspects that at first they served as a refuge from adverse conditions – particularly drought.
It seems that the animals dug whenever the opportunity presented. Even some dinosaurs dug burrows. That’s just the soil is not always allowed. In the Moroccan case, the conditions were perfect: a local facility built in the sand, mixed with the wet mud of floodplain channel.
