By these measures, Argentinosaurus was the largest dinosaur, as well as the largest land animal, ever known.
What was the largest land animal ever?
Blue whales are the largest animals ever to have lived. They are bigger than even the largest of the dinosaurs. They can grow to be as large as a jumbo jet! The biggest mammal that ever roamed the land was Paraceratherium.
What is the largest dinosaur bone ever found?
Dinosaur fossils could belong to the world’s largest ever creature. Paleontologists discovered the fossilized remains of a 98 million-year-old titanosaur in Neuquén Province in Argentina’s northwest Patagonia.
Is titanosaur bigger than argentinosaurus?
The huge size of each suggests the dinosaur was a very large titanosaur—one that might be bigger than Argentinosaurus. That claim cannot be confirmed, however, until leg bones are found. … Titanosaurs belong to the sauropod family, which means they were herbivores, had massive bodies and long necks and tails.
Why can’t dinosaurs live today?
DNA breaks down over time. The dinosaurs went extinct around 66 million years ago and with so much time having passed it is very unlikely that any dinosaur DNA would remain today. While dinosaur bones can survive for millions of years, dinosaur DNA almost certainly does not.
What animal are the smartest?
Dolphins are well-documented as intelligent animals. They can recognize themselves in a mirror and communicate with each other. Their large brain is structured for awareness and emotion, and dolphin brains are even more structurally complex than those of humans.
Are dinosaurs still alive?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Are Dinosaurs Real?
Dinosaurs are a group of reptiles that have lived on Earth for about 245 million years. In 1842, the English naturalist Sir Richard Owen coined the term Dinosauria, derived from the Greek deinos, meaning “fearfully great,” and sauros, meaning “lizard.” Dinosaur fossils have been found on all seven continents.
What is the smallest dinosaur in the world?
Answer: The smallest dinosaurs yet discovered are: A new, crow-sized theropod, Microraptor was recently found in China. It is about 16 inches (40 cm long) and may be an adult. Compsognathus, a theropod (meat-eater) 2 feet (60 cm) long, from 145 million years ago.
Who was the strongest dinosaur?
A: The strongest was probably the biggest, ultrasauros, who was six-stories high. Or, among meat-eaters, T. rex. Q: In the book The Biggest Dinosaurs by Michael Berenstain, it says that the seismosaurus, found in Mexico, might be larger than the ultrasaurus.
Why does at Rex have small arms?
The precise purpose of T. rex’s relatively tiny arms has long been mysterious. Over the years, scientists have suggested that they might have been used to grasp struggling prey, to help resting dinosaurs push themselves up from the ground, or to grip tight to mates during sex.
What was the largest water dinosaur?
Ichthyosaurs. The largest ichthyosaur was Shonisaurus sikanniensis at ~21 metres (70 ft) in length. This would make it the largest extinct marine animal.
Will humans go extinct?
The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct. … Humans are inevitably heading for extinction.
Can we bring back the dodo?
The flightless bird, native to the Indian Ocean island of Mauritius, nested on the ground and laid only one egg at a time. Settlers who arrived in 1638 brought cats, rats and pigs that devoured dodo eggs. “There is no point in bringing the dodo back,” Shapiro says.
What if dinosaurs never went extinct?
“If dinosaurs didn’t go extinct, mammals probably would’ve remained in the shadows, as they had been for over a hundred million years,” says Brusatte. “Humans, then, probably would’ve never been here.” … Gulick suggests the asteroid may have caused less of an extinction had it hit a different part of the planet.
