Long neck dinosaurs
Long neck dinosaurs are from the Jurassic period and are also called ''long necks''. Long necks form a group of dinosaurs called sauropods. Sauropods are the biggest dinosaurs that we know of. A few long necks are: Apatosaurus, Diplodocus, Ultrasaurus and Brachiosaurus(see bellow). They ate a gigantic amount of food every day. They were alive in the Jurassic period because the Jurassic climate was wet and warm which is ideal for reptiles. The main predator of long necks was the powerful Allosaurus. Allosaurus was a 37 meter long carnivore and enjoyed feasting on many Jurassic dinosaurs. Some long necks such as Diplodicus had a few defenses besides its intimidating size: thumb spikes and a whiplash tail. All long necks lived together in large herds. They enjoyed feasting on tree ferns and other lush vegetation. Brachiosaurus (bellow), is a well known long neck has and nostrils on the top of its head.
