The biggest dinosaur fossil ever discovered is that of the Argentinosaurus. It was a type of sauropod dinosaur that lived during the Late Cretaceous period, about 100 million years ago. It is estimated to have been up to 100 feet (30 meters) long and weighed up to 110 tons (100 metric tonnes). This makes it one of the largest land animals to have ever existed.
Where was the largest dinosaur found?
The fossils of the Argentinosaurus were discovered in Argentina, specifically in the Neuquén Province, in the western part of the country. The first fossils of Argentinosaurus were discovered in the early 1980s by Guillermo Heredia, a local farmer, and later studied by Jose Fernando Bonaparte and Jorge Orlando Calvo. It was found in the Rio Limay Formation, which is a geological formation that dates back to the Late Cretaceous period. The fossils of Argentinosaurus are now housed in several museums in Argentina, including the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires.
What is the most complete dinosaur skeleton ever found?
The most complete dinosaur skeleton ever found is that of the Tyrannosaurus rex named "Sue". Sue was discovered in 1990 by paleontologist Sue Hendrickson in the Black Hills of South Dakota, USA. The skeleton is approximately 90% complete and includes the skull, which is nearly complete. The bones have been well preserved and are in excellent condition, making Sue one of the most valuable and scientifically important fossils of any dinosaur ever found. It is the largest and most complete T. rex skeleton ever found and it is currently on display at The Field Museum of Natural History in Chicago. The T. rex named "Scotty" is also considered one of the most complete T. rex ever found, and it was found in Canada in 1991. It is about 65% complete.
Is there a dinosaur bigger than argentinosaurus?
Argentinosaurus is currently considered to be one of the largest known dinosaurs, if not the largest. However, it is important to note that the estimates of the size of dinosaurs are based on fragmentary fossil evidence and subject to ongoing scientific debate. Other sauropods, such as the Futalognkosaurus, Puertasaurus, and Dreadnoughtus, are also believed to have been as large or even larger than Argentinosaurus. But their size is also based on fragmentary remains and their size estimates are less certain. Some studies suggest that these sauropods were bigger than Argentinosaurus, but it is hard to confirm it with the current fossils and research. It's also worth noting that size estimates are not always accurate, and the size of dinosaur fossils can vary greatly depending on the method used to estimate them.
In summary, while Argentinosaurus is currently considered one of the largest dinosaurs, there may be other sauropods that were as large or larger, but the current evidence is not enough to confirm it.
How big was the biggest T rex ever found?
The biggest T. rex ever found is the one named "Sue", which was discovered in 1990 in South Dakota, USA. The skeleton is approximately 90% complete and includes the skull, which is nearly complete. The length of Sue is estimated to be around 12.8 meters (42ft) and it is estimated to have weighed around 11,000 kg (12 tons). It should be noted that estimating the size of T. rex and other dinosaurs is challenging and can vary depending on the method used. The size of "Scotty" also considered one of the most complete T. rex ever found, is estimated to be around 12.3 meters (40ft) and estimated to have weighed around 9,100 kg (10 tons).
It's worth noting that these measurements are estimates and there is some variation in estimates depending on the methodology used.
What is the biggest animal that has ever lived?
The blue whale (Balaenoptera musculus) is considered the largest animal that has ever lived. Blue whales can grow up to 100 feet (30 meters) long and can weigh as much as 200 tons (180 metric tonnes). They are found in all of the world's oceans and are known for their distinctive vocalizations, which can be heard for miles. Blue whales feed on tiny marine animals called krill, consuming up to 4 tons of krill per day. It's worth noting that the largest animals to have ever lived are all aquatic and include other whale species such as the Fin Whale (Balaenoptera physalus) and the Bowhead Whale (Balaena mysticetus) and some species of prehistoric marine reptiles such as the Mosasaurus and the Liopleurodon.
