The Australian Kronosaurus is the second largest well-known Pliosaurier. Its flat head was 2.7 m long. Thus it was clearly more largely and also more strongly than those of the largest carnivorous dinosaurs, e.g. Tyrannosaurus. During the Trias and law Australia dry country had been. But in the Unterkreide flooded flat seas far parts of the continent and created rich fischgruende, in which Kronosaurus and other kurzhalsige Pliosaurier, which were all quite good floats, found sufficient food. One found remnants of other maritime Saurier as well as turtle tanks in its stomachs. In addition might have belonged both fish and Ammoniten and tintenfische to its booty spectrum. Kronosaurus had sharp teeth in front and rounded molars, with which he could crack each bowl and nearly each tank. It was one the Top hunter of the seas of the earth Middle Ages.
