Deinosuchus

名字的意思： “terrible crocodile”1

吃：肉史前傳奇白堊紀晚期不是恐龍，而是史前傳奇

Deinosuchus was a giant crocodile-like reptile that lived during the Late Cretaceous, about 82 to 73 million years ago. It was one of the biggest crocodilian predators ever, growing longer than a school bus! Even though it looked like a crocodile, it was actually more closely related to alligators.1

這隻不是恐龍，但牠是史前時代最有名的動物之一，所以在 Dino Wiki 也有一席之地。

酷東西

趣味知識

Deinosuchus could grow over 9 meters (30 feet) long, making it one of the largest crocodilian relatives ever.1

Its back was covered in thick, round bony plates called osteoderms, which acted like armor.1

Scientists think Deinosuchus may have lived for up to 50 years, growing slowly but for a very long time.1

Deinosuchus lived on both sides of the Western Interior Seaway, a huge sea that split North America in two during the Cretaceous.1

Bite marks on dinosaur bones show that Deinosuchus attacked and ate large dinosaurs.2

The first Deinosuchus fossils were found in North Carolina in the 1850s, but the animal was not named until 1909.1

Deinosuchus had a longer skull than modern crocodiles and alligators, and its teeth were built for crushing.1

發現: The first Deinosuchus fossils were found in North Carolina in the 1850s, but the genus was named in 1909 by William Holland based on fossils from Montana. Later, in the 1940s, more complete remains were found in Texas by an American Museum of Natural History expedition led by Barnum Brown and Roland Bird.1 2
仍有爭議: Scientists still debate whether Deinosuchus from eastern and western North America were different species or just one species that lived across a wide area.2
