恐竜説明: The Age of the Dinosaurs seems to have had more than its fair share of giant meat eaters. The theropods were terrifying and, with gigantic pterosaurs patrolling the skies and fearsome mosasaurs menacing the oceans, nowhere was safe. And if these weren't enough, add one of the world's largest crocodiles skulking on the river bank and life becomes a nightmare world.
Deinosuchus was a huge creature with a 2‑m‑long (6 ft 6 in) skull and about a hundred large teeth. The teeth were very sturdy and the front, or incisor, teeth were razor sharp. Towards the back of the jaws the teeth were made for crushing.
Deinosuchus was a four-legged monster with a long tail. Normally, it would lie in wait in shallow water or rest on the river bank, but in attack it was a powerful swimmer. It could even lift its body and outrun unsuspecting prey over short distances.
The discovery of Sarcosuchus imperator (meaning 'Flesh Crocodile Emperor') in Niger, West Africa, in 1996, challenged the position of Deinosuchus as the world's largest ever crocodile. Whichever was the winner, both probably ate dinosaurs.
