The long-necked dinosaur is called a sauropod, which is a group of plant-eating dinosaurs with long necks, small heads, and four thick legs. Some examples of sauropods include:
- Apatosaurus: A massive sauropod that lived in the late Jurassic period, around 156-151 million years ago. It was around 22 meters in length and weighed up to 22 tons. Its neck measured a huge 5.9 meters.
- Brachiosaurus: A sauropod that lived in North America and Africa during the Jurassic and early Cretaceous periods. It was a plant-eating dinosaur that measured around 75 feet long and 41 feet tall, weighing approximately 89 tons. Its forelimbs were much longer than its hind limbs, and its neck was the longest of any animal to ever live.
- Diplodocus: A herbivorous dinosaur that lived 150 million years ago during the late Jurassic period. It had four large, sturdy legs to support its long neck and whip-like tail. It measured around 98 feet in length and weighed around 16 tons. Its neck could reach over 6 meters (20 feet) and its long tail had 80 vertebrae.
- Mamenchisaurus: A sauropod that lived in China during the Jurassic period. It had the longest neck of any animal to ever live, sometimes measuring up to half the length of its body.
- Argentinosaurus: The largest land animal to have ever lived, weighing an estimated 70 tons and measuring 122 feet (37 meters) long. It was also a sauropod with a very long neck.
These are just a few examples of the many sauropods that existed during the Mesozoic Era.
