The Dreadnoughtus was one of the largest dinosaurs to be discovered. This dinosaur lived somewhere between 84 million and 55 million years ago during upper cretaceous period in the Campanian and Masstrichian geoclinal timeline.
Dreadnoughtus weight
The estimated weight of the Dreadnoughtus is 65 tons which is equivalent to twenty H2 Hummers or seven Tyrannosaurus species. It is nearly double the size of a Brachiosaurus. The mass of dinosaurs such as this Titanosaur are accurately measured by the femur and the humerus. Other extinct Sauropod in the Titanosaur family are also very large such as the Argentinosaurus, Gianotosaurus, and Supersaurus.
About Dreadnoughtus Fossils
Dreadnoughtus is known from one holotype specimen and one paratype specimen. The most recent discovery was an impressive 142 bones equaled at a 70.4% complete skeleton. The previous discovery was a partially articulated postcranial skeleton. Both specimens were discovered in the Cerro Fortaleza Formation of Santa Cruz province, Argentina.
About the Cerro Fortaleza Formation
The Fortaleza Formation is located in the Rio La Leona Valley in Santa Cruz Province, Argentina. It is often referred as the Pari Aike, Chorrillo, or Mata Amarilla Formation. The Cerro Fortaleza Formation is clearly terrestrial and consists predominantly of cross-bedded, friable sandstones inner bedded with layers of mudstones and occasional lignitic horizons.
Cerro Fortaleza Formation has brought many discoveries such as extinct shark teeth, dipnoan teeth, testudine shell fragments, semionotiform/lepisoteid scales, and Chondrichthyan teeth, Agathoxylon, Planoxylon, Taxodioxylon, Cupressinoxylon, and Podocarpoxylon.
About The Dreadnoughtus
A lot of information about Dreadnoughtus can be said due to the most recent discovery being a 45% complete skeleton. This herbivore is 85ft long and 30ft tall. 20ft tall to the dinosaurs shoulder, 37ft long neck, and a 30ft long tail. The Sauropod weighed 59.3 metric tons or 130,734 pounds. The name Dreadnoughtus means “fearer of nothing”. It comes from powerful battleships called dreadnoughts due to them being constructed to be invulnerable to attack. Dreadnoughtus probably spent its days munching massive quantities of plants to fuel its enormous body.

- MPM-PV 1156: This was a partial skeleton of the dreadnoughtus fossil to be discovered. The layout of only somewhat preserved. It consisted of a fragment of a maxilla, a tooth, a posterior cervical vertebra, cervical ribs, multiple dorsal vertebrae and dorsal ribs, the sacrum. For the tail skeleton, thirty two caudal vertebrae and eighteen haemal arches that include a sequence of seventeen anterior, middle caudal vertebrae, and their corresponding haemal arches were discovered in their original layout. Also the left pectoral girdle, forelimb, minus the front foot, both sternal plates, the full pelvic elements, the left hind limb lacking a hind foot and right tibia, metatarsals I and II, and one claw from digit I. MPM-PV 1156 is a holotype specimen.
- MPM-PV 3546: This discovery was a younger and smaller dreadnoughtus. It consisted of a partial anterior cervical vertebra, multiple dorsal vertebrae and ribs, the sacrum, seven caudal vertebrae and five haemal arches, a nearly complete pelvis, and a left femur. MPM-PV 3546 is a paratype specimen.
