Sur la terre des dinosaures (6/6)

La fin du crétacé, il y a 65 millions d'années, est marquée par la disparition de la dynastie des dinosaures. L'un de ses derniers représentants est le tyrannosaure, le plus formidable prédateur avec ses 5 tonnes de muscles.

@Alevinmaker Dinosaur is referred to a lizard from ancient times... Now the science discovered that they were not all lizards but also birds...Now a dinosaur may be referred to any avian, non avian, marine, reptilian or amphibian... thousands of species... discovered in the fossils of the Triassic/ Cretaceous / Paleogene periods.

@2Pains1 Ok, I know that monkey never became human, but when you say they have same ancestry I beg we are fine because this is what I'm saying too and that's the same for crocodiles and Deinosochus. Dinosaurs were'nt only biped, but there were some quadruped and avian dinosaurs. So how could I know that Deinosochus wasn't dinosaur ? He was at least a dinosaur hunter so he lived just before the K-T extinction, thats why I believed it was dinosaur. What's dinosaur and what is not ?

@Alevinmaker There are some anatomical facts we use when defining dinosaur. First, its legs stretch out from its main body to the ground STRAIGHT. Have you ever seen crocodile standing on its legs straight? I'm sure you never did. There are also other features, like: Land animal, number of skeletal holes, reptilian skin, etc. Surely crocodiles share some of these features since they have same ancestry, but dinosaurs are more like relative of crocs, not its ancestor.

@Alevinmaker It's you who got the fact wrong. Besides, monkey never became human. MOnkey and Human have 'same' ancestors. Dinosaurs and crocodiles/turtles are in same relationship. Also, Deinosuchus was not even a dinosaur. Deinosuchus is a 'crocodile' lived in cretaceous and earlier crocodiles first appeared in triassic. If you wanna tell me I don't know what I'm talking about, at least google and check the fact, period.
