When we think of the worlds tallest dinosaurs there is always one name most people will mention and that is the Diplodocus. While it does indeed make this top 10 list it isn’t our number 1 tallest, that comes to something almost unpronounceable…
Ten of the Worlds Tallest Dinosaurs That Ever Lived
10 – Savannasaurus from the Titanosauridae Family – Estimated Average Height: 29.9 ft(9.10 m)
Savannasaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous of Queensland, Australia, containing one species, Savannasaurus elliottorum, named in 2016 by Poropat et al.
9 – Diplodocus from the Diplodocidae Family – Estimated Average Height: 30 ft(9.14 m)
Diplodocus is an extinct genus of diplodocid sauropod dinosaurs whose fossils were first discovered in 1877 by S. W. Williston. When most kids have a tall toy dinosaur, it is often one of these.
8 – Mamenchisaurus from the Euhelopodidae Family – Estimated Average Height: 33 ft(10.05 m)
Mamenchisaurus is a sauropod dinosaur genus including several species, known for their remarkably long necks which made up half the total body length.
7 – Haplocanthosaurus from the Cetiosauridae Family – Estimated Average Height: 34 ft(10.36 m)
Haplocanthosaurus is a genus of sauropod dinosaur. Two species, H. delfsi and H. priscus, are known from incomplete fossil skeletons. It lived during the late Jurassic period, 155 to 152 million years ago.

6 – Bothriospondylus from the Brachiosauridae Family – Estimated Average Height: 35 ft(10.66 m)
The type species, Bothriospondylus suffossus, was described by Richard Owen in 1875. The specific epithet suffossus means “undermined” in Latin, a reference to the fact that pleurocoels had hollowed out the sides of the vertebra.
5 – Barosaurus from the Diplodocidae Family – Estimated Average Height: 39 ft(11.88 m)
Barosaurus was a giant, long-tailed, long-necked, plant-eating dinosaur closely related to the more familiar Diplodocus. Remains have been found in the Morrison Formation from the Upper Jurassic Period of Utah and South Dakota.
4 – Andesaurus from the Titanosauria Family – Estimated Average Height: 40 ft(12.19 m)
Andesaurus is a genus of basal titanosaurian sauropod dinosaur which existed during the middle of the Cretaceous Period in South America. Like most sauropods, it would have had a small head on the end of a long neck and an equally long tail.
3 – Brachiosaurus from the Brachiosauridae Family – Estimated Average Height: 50 ft(15.24 m)
Brachiosaurus is a genus of sauropod dinosaur from the Jurassic Morrison Formation of North America. It was first described by Elmer S. Riggs in 1903 from fossils found in the Grand River Canyon of western Colorado, in the United States.

2 – Argentinosaurus from the Titanosauridae Family – Estimated Average Height: 70 ft(21.33 m)
Argentinosaurus is a genus of titanosaur sauropod dinosaur first discovered by Guillermo Heredia in Argentina. The generic name refers to the country in which it was discovered. The dinosaur lived on the then-island continent of South America somewhere between 97 and 93.5 million years ago, during the Late Cretaceous Period. It is among the largest known dinosaurs.
1 – Seismosaurus from the Diplodocidae Family – Estimated Average Height: 84 ft(25.60 m)
In 1991, palaeontologist David Gillette announced that he had found the largest of the enormous sauropod dinosaurs. He called it Seismosaurus halli, and based on the parts of the skeleton that had been prepared at the time, Gillette believed Seismosaurus to be between 127 and 170 feet long plus the tallest of all the dinosaurs when on its back legs eating from the tallest of trees.
