Everybody loves dinosaurs. We all love those huge majestic prehistoric creatures that roamed the earth in ancient times. Various dinosaur species have been featured across popular media, From “Jurassic Park” to “The Land Before Time.” According to the American Museum of Natural History, scientists have been able to discover over 700 species of dinosaurs.

You’ve probably read about the deadliest dinosaurs that ever lived, or the Jurassic Park dinosaur movies, or some dinosaur videos on youtube, but have you ever wondered what are the top biggest dinosaurs have been discovered?

Dinosaurs are some of the most exotic creatures the world has ever known. Some dinosaurs were so huge, they were as tall as skyscrapers, much bigger than the elephant and the humpback whale (the largest living animals in modern times). We can just meet them in a dinosaur movie. A pity we never got to meet them.

Well, if you are curious about these titanosaurs that most live in the Mesozoic Era (about 252 million to 66 million years ago), then here is the list for you. It includes:

Amazingly, most dinosaurs on this list are herbivores. If humans existed in prehistoric times, the only danger would probably be getting unwitting squashed under the massive weight. Do you know the dinosaur names of these?

If you’re ready, let us explore some of the biggest dinosaurs that have been discovered.

Biggest Dinosaurs That Have Been Discovered

Type: Sauropod

Period: Late Cretaceous

Size and Weight: 98 to 115 feet in length and 88 to 110 tons in weight

Diet: Herbivore (foliage)

The Argentinosaurus huinculensis is considered as the biggest dinosaur ever found. This largest land animal existed around 97-93.5 million years ago, is estimated to be as long as 30 to 40 metres and is believed to have weighed between 60 and 124 tonnes. The Argentinosaurus lived in South America and was part of a subgroup of dinosaurs called the titanosaurs. Archaeologists have also compared it to other popularly known dinosaurs like the diplodocus and the apatosaurus because of its long neck and tail and because it was also a herbivore. If you want to know more about the Argentinosaurus, the blog A Fun Guide to Long Neck Dinosaurs [With 10 Dino Names] is also a good choice.

Size and Weight: up to 26 meters (85 feet) in length and more than 60 tons in weight

Diet: Herbivore

The Dreadnoughtus schrani is the longest dinosaur that has ever walked on land and whose body mass can be accurately measured. The dinosaur is 85 feet long and weighs a whopping 65 tons. This means that it has a combined size of 12 African elephants or more than seven Tyrannosaurus rex dinosaurs.

The difference between the accurate size of Argentinosaurus huinculensis and the Dreadnoughtus schrani is that while the Argentinosaurus was possibly more prominent than the Dreadnoughtus, there is no simple method of calculating the actual size of the Argentinosaurus because it lacks upper limb bones and its vertebrae only starts from the middle of its back.

Period: Late Cretaceous

Size and Weight: 40 meters (131 feet) in length and 85 tons in weight

Diet: Herbivore

The Patagotitan mayorum has been described as the biggest dinosaur to have ever been discovered. Although there are currently no complete skeletons, the existing fossils have been able to prove that it was on par with several other dinosaur giants such as Argentinosaurus. The dinosaur is a subgroup of titanosaur dinosaurs that grew prominent in Patagonia, a place in South America, about 100 million years ago. The Patagotitan mayorum weighed 76 tons when researchers estimated it — that is, it was the size of 10 African elephants. It was also 122 feet long and was almost 20 feet high.

Scientists have said that they were not scary animals and that they were probably slow-moving animals who found it difficult to get up, walk around or try to run. It Is also believed that the dinosaurs got so big because there was a lot of food for the dinosaurs to eat. The Patagonian Mayorum’s bone formation is incomplete — meaning that there are probably even more enormous than we think.

Size and Weight: up to 15 meters (49 feet) in length and 3 to 6 tons in weight

Diet: Herbivore

The Rapetosaurus is one of the longest and largest herbivorous dinosaurs to have ever existed. It is a sauropod dinosaur that lived in present-day Madagascar, sub-Saharan Africa, some 70 to 66 million years ago. It is estimated to be as long as 15 metres. Archaeologists have described the Rapetosaurus as having a short and slim tail, a very long neck and a big body, like an elephant. It also had small teeth for ripping leaves from trees.

Size and Weight: 12 meters (39 feet) in length and 8 tons in weight

Diet: Herbivore

The Saltasaurus is a herbivorous dinosaur that lived between 70 and 65 million years ago. Saltasaurus means “lizard from Salta”, and even though the animal was a relatively small dinosaur, it was still significant compared to the size of humans.

The Saltasaurus was a herbivorous animal with an estimated length of 12 metres and a mass of 7 tonnes and is believed to use its hind legs to reach higher branches of a tree.

Diet: Herbivore

The Austropeidon magnificus is one of the biggest and longest dinosaurs that has been discovered in Brazil, reaching up to 82 feet long from tip to tail. It is quite hard to estimate the length of ancient dinosaurs since only a few bones are available for scientists to examine correctly. The Austropeidon was a great animal, nonetheless.

The Austropeidon was discovered in 1953 by a group of paleontologists from the Baaru Group. The scientific name of the dinosaur was taken from the Greek god of earthquakes of the same name. The Latin word magnificus means tremendous or noble since the relic was huge.

The Paraltitan was a giant sauropod dinosaur that lived in present day Egypt between 99 and 94 million years ago. It was a herbivorous dinosaur that was as long as 28 metres. The Paralititan had an estimated body mass of 65.3 tonnes to 72.5 tonnes, with an estimated weight of 50 tons.

Scott Harman, a very influential scientist, has estimated that even though the Paralititan is a giant dinosaur, it is smaller than the enormous dinosaurs such as the Puertasaurus, the Alamosaurus, and the Argentinosaurus.

Size and Weight: 26 feet (8 meters) long in length and 5.5 tons in weight

Diet: Herbivore

The newly-discovered Shingopana songwensis is a dinosaur that lived between 100 and 70 million years ago. A partial skeleton of the Shingopana was only discovered in 2012 in Tanzania through the Rukwa Rift Basin Project, an effort led by paleontologists at the Ohio State University.

Shingopana” is a Swahili word for a wide neck, and the average Shingopana dinosaur can reach up to 8 metres when fully grown. The structure of the Shingopana is fascinating because it has four vertical backbones or vertebrae. Two of these backbones are preserved cervical ribs, while the other is an isolated cervical rib.

Generally, the giant sauropods can be divided into two categories: the shorter but stockier and more massive forms (mainly titanosaurs and some brachiosaurids ). The Diplodocus is second type sauropod dinosaur that lived between 152 and 154 million years ago and was first discovered in 1877 by a scientist named S.W. Williston. The Diplodocus is one of the longest dinosaurs ever discovered, with its oversized shape, long neck, long tail, and muscular legs. The Diplodocus carnegii is regarded as one of the longest dinosaurs from a complete skeleton, with a total length of 24 metres and an extremely long tail.

The Diplodocus has been described as one of the most dangerous animals ever, and many experts allude to the fact that it can attack its enemies at the speed of light because of its 20-foot long tail and its 100-foot size.

The Brachiosaurus is a type of sauropod dinosaur that lived in North America about 154-153 million years ago. The Brachiosaurus is estimated to have been between 18 and 21 metres long, with an estimated weight of 28.3 to 58 metric tons. It had a long neck, a small skull, and a large size, including longer forelimbs than hind limbs and a shorter tail, the typical structure of a sauropod dinosaur.

The Torvosaurus dinosaur is one of the largest carnivorous dinosaurs to have ever been discovered. The Torvosaurus lived approximately 165 to 148 million years ago in many parts of America, Europe and Africa, including Colorado, Portugal, Germany, England, Tanzania and Uruguay.

The Torvosaurus is organised into two species: Torvosaurus tanneri and the Torvosaurus gurneyi, including an unnamed species from Germany. The dinosaur is among the largest dinosaurs ever discovered, and it can grow as long as 12 metres. It was also estimated to have arms that were short but very powerful.

The Spinosaurus takes the prize as the largest carnivorous dinosaur, It is the Top 12 Largest Meat-eating Dinosaurs That Ever Lived, believed to be even bigger than other dinosaurs like the Tyrannosaurus, Giganotosaurus, and the Carcharodontosaurus. The Spinosaurus’ length is estimated to be between 12.6 to 18 metres, and it could even grow as long as 15 to 16 metres. An interesting thing is that the enormous size crocodile Sarcosuchus, the world’s largest crocodile, may sometimes be mixed with Spinosaurus.

Scientists believe that the Spinosaurus used to eat fishes and other animals inland and on water, and there is enough evidence to support the fact that the Spinosaurus used to live in both land and water.

Diet: Herbivore (conifers and early flowering trees)

The Sauroposeidon is a sauropod dinosaur that existed in American states over 40 million years ago. This big dinosaur had an unusual size, and estimates suggest that it could reach 17 to 18 metres if its neck were extended, making it one of the tallest dinosaurs ever known. The sauroposeidon is estimated to have a body mass of 40 to 60 tons, effectively making it one of the longest and heaviest dinosaurs to have ever existed.

Sauroposeidon is a name that translates to “lizard earthquake god”, and it possibly lived in the American states of Oklahoma, Wyoming, and Texas.
