Their fossils have been found by scientists in Morocco. They inhabited the seas in the ordovcico period, does between 488 and 472 million years. Scientists of the American university of Yale discovered, according to has occurred to know this week, in Morocco the fossils of ” extraas” giant creatures who inhabited the Earth seas in the ordovcico period, do between 488 and 472 million years. In a study published in the last number of the Nature magazine, the investigators Peter Van Roy and Derek Briggs consider that the anomalocardidos ones, giant predators with soft bodies and two thorny appendices that leave the mouth, of aspect similar to the prawns, were habitual marine creatures by a much more long time than was believed until now. One is strange animal with a mouth of sharpened teeth, equipment to perforate the armors of small arthropods like trilobites, and lobes in order to move in the water. The oldest specimens of those creatures, met like ‘ prawns extraas’ , they date from the average Cmbrico, does between 542 and 501 million years. The fossils shortages now are much majors that those of the Cmbrico which they were known until now, and each of them measures near a meter. The fact that the animal found in Morocco were 30 million years younger than those than they inhabited the Earth in the Cmbrico indicates that the anomalocardidos ones dominated the marine ecosystems long before which thought.
