Microvenator (meaning “small hunter”) was a small, fast-moving, lightly-built dinosaur that walked on two long legs. It was about 4 ft. (1.2 m) long and weighed roughly 6.5 to 14 pounds (3 to 6.4 kg). This turkey-sized predator had short arms, large eyes, a long neck, a small head, and a long snout tat may have had a toothless beak. Each hand had three long fingers, each equipped with a claw.
igongosaurus was a large quadrupedal (walked on four legs) herbivore. It was a about 35 feet (10.7 m) long and may have weighed about 20 tons. It had a long neck, a long tail, a small head with spoon-shaped teeth, and thick, elephant-like legs. Zigongosaurus lived during the late Jurassic period. Zigongosaurus was an herbivore, a plant eater. It stripped foliage with spoon-shaped teeth. It used to be thought that the sauropods (like Zigongosaurus, Brachiosaurus and Apatosaurus) and Stegosaurus had a second brain.
Vulcanodon was about 20 feet (6.5 m) long. It was a long-necked, long-tailed plant-eater with a small head, thick legs, and a bulky body. It […]
Majungatholus atopus, or popularly known as Majungasaurus was a meat-eating dinosaur, a therapod. It was up to 30 feet (9.1 m) long and was at the top of the food chain in its locale. It probably ate sauropods, long-necked plant-eaters and other large dinosaurs.
Dsungaripterus was a pterosaur with 10 feet (3 m) wide leathery wings. It had an unusual bony crest running along its snout and had long, narrow, curved jaws with a pointed tip. It had flat teeth at the back of the jaws, probably for crushing the shells of its prey. It was not a dinosaur, but a type of extinct, flying reptile. They were lightly built with hollow bones, long, curved necks, long skulls, and small bodies. They had large brains and good eyesight.
This dinosaur, unlike other, is a different type of dinosaur, with a 7 inch puffed head, used for defensive purposes. Small in size gave it advantage, it made it extremely agile. Agility made it faster, thus saving it from predators. It’s puffed head was used for butting, and even for territorial defence.
Ankylosaurus was a huge armored dinosaur, measuring about 25-35 feet (7.5-10.7 m) long, 6 feet (1.8 m) wide and 4 feet (1.2 m) tall; it […]
Dilophosaurus was a speedy, slender, bipedal (walked on two legs), meat-eater that lived during the early Jurassic period. It was a theropod (a meat-eating dinosaur) about 20 feet (6 m) long, about 5 feet (1.5 m) tall at the hip, and weighing about 650 to 1,000 pounds (300 kg to 450 kg). It had two thin, bony, almost semi-circular crests on its head; these may have been for mating displays.
iplodocus was a long-necked, whip-tailed giant, measuring about 90 feet (27 m) long with a 26 foot (8 m) long neck and a 45 foot (14 m) long tail, but its head was less than 2 feet long. It was among the longest land animals ever. Its nostrils were at the top of its head and it had peg-like teeth, but only in the front of the jaws. Its front legs were shorter than its back legs, and all had elephant-like, five-toed feet. One toe on each foot had a thumb claw, probably for protection. A fossilized Diplodocus skin impression reveals that it had a row of spines running down its back. Diplodocus was more lightly built than the other giant sauropods, and may have weighed only about 10-20 tons. Its backbone had extra bones underneath it, which had bony protrusions running both forwards and backwards (anvil shaped), a “double-beam”, probably for support and extra mobility of its neck and tail. It may have used its whip-like tail for protection. A recent Diplodocus skin impression was found, showing a row of spines running down the back. It has been determined that Diplodocus (and the other diplodocid sauropods, like Apatosaurus) could not hold their necks over about 17 feet (5.4 m) off the ground (Parrish and Stevens,1999). Gastralia (hanging belly ribs) are thin, fragile ribs that helped support and protect the internal organs (like the lungs) in the middle area of the body. These ribs were not attached to the backbone; they were attached to the skin in the belly area. It used to be thought that the sauropods (like Diplodocus, Brachiosaurus and Apatosaurus) and Stegosaurus had a second brain. Paleontologists now think that what they thought was a second brain was just an enlargement in the spinal cord in the hip area. This enlargement was larger than the animal’s tiny brain. Diplodocus was a sauropod, whose intelligence was the among the lowest of the dinosaurs.
Psittacosaurus (meaning “parrot lizard”) was a small, very primitive ceratopsian. This fast-moving plant-eater had a narrow, horny beak with no teeth, and cheek teeth towards the rear of the mouth. It had a boxy skull with short, horn-like projections on the cheeks. It had four long fingers on each hand; the arms were much shorter than the legs.
Probably the most well-known flying dinosaur, the Pterodactyl is not actually a dinosaur at all, but a distant cousin called Pterosaur! Pterosaurs were airborne reptiles of the late Jurassic period, and therefore are frequently associated with dinosaurs in the popular imagination. Pterodactyl used to soar through the pre-historic skies of what is now Europe and northern Africa.
