Ever wonder what the biggest dinosaur was? According to paleontologist Alejandro Otero, determining the size of the largest of them is difficult. After all, there were no gigantic scales that they could step on during their lifetime. In most cases, paleontologists have to guess based on incomplete fossil records. Then, when they learn more about sauropods, they may find themselves filling up with air sacs, making them smaller than they initially appeared.
In addition, there is the problem of the disappearance of fossils. For example, the 19th century fossil hunter E.D. Cope claims to have found a fossil that is twice as large as any other fossil, but mysteriously disappeared. The fossils of Bruhathkayosaurus in India have disintegrated and are no longer available for study.
However, we have tried to list the largest types based on their length. First, we took into account the length of the dinosaur. Then their weight is according to this list.
# 10 The largest dinosaurs in the world: Xinjiang titan shanshanaisis – 98 feet long
IN Xinjiang titan shanshanaisis lived in the northwest of China in the Middle Jurassic period. Scientists believe that this dinosaur had the longest neck that ever existed, judging by the fossils found in Xinjiang. Some evidence suggests that this type may have been as little as 88.6 feet in length but was over 56 feet in height. He weighed approximately 88,000 pounds.
# 9 The largest dinosaurs in the world: Gatesaurus reuili – 98 feet long
The only fossils found in Gatesaurus reuili came from the late Cretaceous period. They were found in southwestern Patagonia, Argentina. Paleontologists believe this dinosaur was about 98 feet long and weighed roughly 110,000 pounds. Its recorded dorsal vertebra, 5 feet 6 inches, is the widest fossil vertebra ever found. The size and shape of this vertebra indicates that it may have had a very wide ribcage. Consequently, it could be heavier than other species of the same period.
Scientists believe this dinosaur had a more flexible neck than most. Consequently, he could eat a wider diet than people with stiff necks. This could be a big advantage because he could find food without going too far.
# 8 The largest dinosaurs in the world: Swimsuit Patagotitan – 98 feet long
Experts believe that Swimsuit Patagotitan lived in the Late Cretaceous period, about 97 million years ago. Unlike many dinosaurs, where scientists have to guess a lot, 84 fossils have been found in the Argentine region of Patagonia. They are on display at the American Museum of Natural History. Its length exceeds 121 feet, but many experts believe that this is a mistake in how the fossils were collected. They think this species was only about 98 feet long.
Paleontologists believe that if this dinosaur pointed its neck straight up, it would be taller than 164 feet. Scientists believe they have fossils of six different animals that returned to the bottom of the lake at different times. They believe that dinosaurs could die due to the fact that the lake dried up at different times, so the dinosaurs could not get enough water. This dinosaur weighed about 152,000 pounds.
# 7 The largest dinosaurs in the world: Ruyangosaurus giant – length 102 feet
Very little is known about Ruyangosaurus giant… Chinese paleontologists found fossils in China in 2009. They believe that the fossils date back to the Early Late Cretaceous. Based on these limited fossils, which are the only ones found from this dinosaur, scientists believe it was about 102 feet long. They also think that this dinosaur weighed about 100,000 pounds.
# 6 The largest dinosaurs in the world: Sauroposeidon Proteles – 105 feet long
IN Sauroposeidon Proteles lived in Texas, Oklahoma, and Wyoming during the Early Cretaceous. This dinosaur, which could be up to 105 feet long, could reach 55 feet in height. He could weigh 112,000 pounds. The first fossils were discovered in Oklahoma in 1994, and they were deposited in the Oklahoma University vault because they were believed to be petrified wood. It wasn’t until six years later that a graduate student discovered the error and realized that it was one of the largest dinosaur bones ever discovered.
If this dinosaur could stick its head straight into the air, it would probably be about 59 feet tall, but only about 105 feet long. He could weigh up to 132,000 pounds. If you want to see Sauroposeidon Proteles dinosaur footprints, head to Dinosaur Valley State Park, near Glen Rose, Texas.
# 5 The largest dinosaurs in the world: Maraapunisaurus fragillimus – 105 feet long
at is sometimes considered the largest dinosaur ever discovered.
Only one fossil from Maraapunisaurus fragillimus has ever been discovered. This fossil has been lost, making it difficult to accurately describe this dinosaur. A vertebral fossil was first discovered and studied in the 1870s, when it was estimated that this dinosaur weighed 300,000 pounds and was over 164 meters long. A later study of field notes suggests that this dinosaur belongs to the Rebbachizaurids. As a result, the size of this North American dinosaur has decreased to 105 feet in length and its weight has decreased to 336,000 pounds. No one will ever know for sure unless a new fossil is found, because the movement of this dinosaur, the only fossil found that has been lost, also requires you to believe there was a typo in the paleontologist’s original report.
# 4 The largest dinosaurs in the world: Argentinosaurus huinculensis – length 108 feet
Although Argentinosaurus huinculensis lived in the Late Cretaceous period, the fossils of this dinosaur were not discovered until 1987, when a farmer working in his fields excavated them near Huincul Square in Argentina. Scientists believe that this dinosaur could move at speeds up to 5 miles per hour and that it simultaneously moved its front and hind legs on each side of its body.
As with many dinosaurs, there is a lot of controversy about the size of this animal. Some believe it was 106 feet long, while others insist that this dinosaur was 130 feet long. It is the same with its weight. Some believe that he weighed only 132,000 pounds, while others believe that he outweighed the scales by more than 220,000 pounds. If more fossils are found, scientists can formulate a stronger hypothesis.
# 3 The largest dinosaurs in the world: Bruhathkayosaurus matleyi – length 112 feet
IN Bruhathkayosaurus matleyi The Indian dinosaur, which lived about 70 million years ago, was originally thought to be about 115 feet long and weighing about 160,000 tons. They later downgraded their grades to about 112 feet in length, but left the weight alone. Even as new scientific methods are developed, further testing of this species is impossible unless new fossils are found. Those that have been studied have disintegrated.
Due to India’s climate, it is unlikely that more fossils will ever be found. Monsoons saturate the fossils, causing them to decay very easily. During the dry season, they increase in size during the day, but decrease in size at night. This often leads to the decay of the fossils.
# 2 The largest dinosaurs in the world: Supersaurus vivianae – length 112 feet
Fossils from Supersaurus vivianae were found in Colorado and may have been found in Portugal. This animal lived about 153 million years ago. In the past, experts believed that this species could reach 141 feet in length, but they lowered their opinion. He could weigh up to 80,000 pounds. This plant-eating dinosaur needed to eat about 1 ton of food every day.
Travelers exploring Wyoming discover the most complete Supersaurus vivianae fossils. About 60% of the animal is present. They reported their findings to the owner of the land. This fossil was named Jimbo. Scientists believe that Jimbo was still very young and was 107 feet long. Scientists believe there was a big fire followed by a landslide that knocked Jimbo down and killed him. Jimbo’s fossils are kept at the Wyoming Dinosaur Center, but they often travel the world for viewing.
# 1 The largest dinosaurs in the world: Barosaurus cool – 125 feet long
Leftovers Barosaurus cool have been found in Utah and South Dakota. These animals were probably about 125 feet long and could have weighed up to 44,000 tons. This dinosaur, which lived about 155 million years ago, had an extra vertebra on its neck compared to many other dinosaurs, so scientists assume that its neck was extremely long.
This dinosaur had forked bones with spikes in its tail. The tail ended in a whiplash. Perhaps this dinosaur knew how to use its tail as a weapon. This dinosaur may have stood on its hind legs to dine on plants far from the ground. When this happened, he may have been 164 feet tall.
Scientists will continue to debate what is the largest dinosaur in the world and its characteristics.
