Argentinosaurus has been known to science since 1993. Evidence of it was originally discovered in 1987, when a fossil the size of a fully grown human being was unearthed on a ranch in Argentina. ... By these measures, Argentinosaurus was the largest dinosaur, as well as the largest land animal, ever known.

Were dinosaurs the biggest animals that ever lived?
Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived. An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg - that's about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.
Why are animals not as big as dinosaurs?
A mammal of a given size uses ten times more energy than does a reptile or a dinosaur of the same size. In other words, mammals can't evolve bodies as large as the largest dinosaurs because they need to use so much of their physical energy – provided by the food they eat – towards keeping their bodies warm.
What was the biggest animal to walk on earth?
The blue whale is believed to be the largest animal to have ever lived. The largest land animal classification is also dominated by mammals, with the African bush elephant being the largest of these.
Is Megalodon bigger than Blue Whale?
No, the blue whale is much bigger. Megalodon was up to 60 feet long, while blue whales are 80 to 100 feet long.
Can dinosaurs come back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
What is the greatest predator of all time?
The title of largest land predator that ever walked on Earth goes to the Spinosaurus. This meat-eating dinosaur lived about 90-100 million years ago. It was about 60 feet long, 12 feet high, and weighed at least seven tons. The Spinosaurus got its name from the massive spikes that ran down its spine.
Do blue whales still exist?
Blue whales are still an endangered species and there are thought to be no more than 25,000 living in the world today.
Did dinosaur ever exist?
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Did dogs evolve from dinosaurs?
Modern dogs evolved from a line of carnivorous mammals called "canids," after the characteristic shape of their teeth. ... Oddly enough, mesonychids were ancestral not to modern dogs or cats, but to prehistoric whales.
Why prehistoric animals were so large?
For a long time, environmental factors such as higher oxygen content in the air and greater land masses (i.e., more space) were thought to contribute to their large size. ... These studies show that dinosaurs of various sizes existed at the same time. And in some cases, they grew smaller rather than larger over time.
What's the biggest creature in the ocean?
The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.
Did Megalodon have any predators?
Mature megalodons likely did not have any predators, but newly birthed and juvenile individuals may have been vulnerable to other large predatory sharks, such as great hammerhead sharks (Sphyrna mokarran), whose ranges and nurseries are thought to have overlapped with those of megalodon from the end of the Miocene and ...
What is the black demon shark?
The Black Demon is said to be between 20-60 feet long and weighing anywhere between 50-100,000 lbs. It is said to resemble a great white shark but with very dark coloration and a large tail. Some say it could be the Megalodon or a new species of shark, or perhaps an unusually large Great White.
Do we have dinosaur DNA?
A team has extracted what could be DNA molecules from a 125-million-year-old fossil dinosaur, according to a study published last month (September 24) in Communications Biology. ... Gizmodo reports the oldest sequenced DNA belongs to a million-year-old woolly mammoth.
Can humans create dinosaurs?
Recent studies show DNA deteriorates and ultimately disintegrates after about 7 million years. ... Dig up a fossil today, and any dino-DNA within would have long since fallen apart. That means, as far as scientists know, and even using the best technology available today, it's not possible to make a dinosaur from its DNA.
Who created dinosaurs?
Sir Richard Owen: The man who invented the dinosaur. The Victorian scientist who coined the word "dinosaur" has been honoured with a plaque at the school he attended as a child.
