Was T Rex the biggest carnivore?
Spinosaurus was larger than both T. rex and Giganotosaurus, which was previously the largest carnivorous dinosaur known. But it’s unclear just how big Spinosaurus was, due to incomplete fossils.
Could a Spinosaurus kill at Rex?
T. rex thus must kill Spinosaurus in order to win, while Spinosaurus only has to drive away T. rex, a much easier task. This asymmetry in conflict goal provides a decisive advantage to Spinosaurus, in which T. rex’s superior intelligence will actually favor Spinosaurus.
Was the Giganotosaurus real?
Today, Giganotosaurus is believed to have been slightly larger than T. rex, though even Giganotosaurus ranks behind Spinosaurus in size among the meat-eating dinosaurs. Giganotosaurus should not be confused with Gigantosaurus, a lesser-known sauropod discovered in England.

Is a blue whale a predator?
Because of their size, power and speed, adult blue whales have virtually no natural ocean predators. The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”. They have been known to work in groups to attack blue whales.
What is the largest mammal to ever walk the earth?

Which animal is at the top of the food chain?
Top of the Food Chain: 5 Deadly Marine Predators
- Killer Whales. When you think of top ocean predators, you probably think of sharks.
- Great White Shark. They can smell a single drop of blood floating in 10 billion drops of water.
- Polar Bears. Although polar bears are land mammals, they spend much of their life at sea.
- Leopard Seals.
- Sea Lions.
Who is at the top of the food chain?
That’s where humans rank, with a trophic level of 2.2. Above us are carnivores, such as foxes, that eat just herbivores. At the top of the scale are meat-eaters that don’t have any predators themselves, such as polar bears and orca whales.
What is the top predator in the food chain?
Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. Food chains are often far shorter on land, usually limited to being secondary consumers – for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers).
Was anything ever bigger than a blue whale?
A blue whale is the largest animal ever known to exist on Earth. It might not seem like it, but we live in a world full of giants. Blue whales are the largest animal ever to move across the planet, with the biggest measuring in at over 100 feet long and weighing hundreds of thousands of pounds.
Is the blue whale bigger than the Megalodon?
Monster-size sharks in The Meg reach lengths of 20 to 25 meters (66 to 82 feet). That’s massive, although a tad smaller than the longest known blue whales. Scientists have made estimates of how big C. megalodon got, based on the size of their fossil teeth. Even the largest reached only 18 meters (about 60 feet).
Are blue whales the biggest animal ever?
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons. Their tongues alone can weigh as much as an elephant.
How old is the T Rex?
T. rex fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous period, which lasted from 67 million to 65 million years ago, toward the end of the Mesozoic Era.
Was the Spinosaurus real?
The skull of Spinosaurus was long and narrow, similar to that of a modern crocodilian. Spinosaurus is known to have eaten fish, and most scientists believe that it hunted both terrestrial and aquatic prey; evidence suggests that it lived both on land and in water as a modern crocodilian does.
How fast does at Rex run?
That’s why gigantic animals like elephants usually aren’t the fastest runners on the block, at least compared to their size. Despite this, many scientists have estimated that the enormous T. rex could run at speeds up to 45 miles per hour. But those figures were just guesses based on eyeballing the dinosaur’s body.
