What would happen if dinosaurs were brought back?
Most dinosaur species haven’t walked the Earth in about 65 million years, so the chances of finding DNA fragments that are robust enough to resurrect are slim. After all, if dinosaurs were alive today, their immune systems would probably be ill-equipped to handle our modern panoply of bacteria, fungi and viruses.
Could T Rex survive today?
It’s doubtful. Tyrannosaurus Rex, and Triceratops for example, lived in the Cretaceous Period 145-66 million years ago (whatever Jurassic Park would have you believe).
What dinosaur was bigger than the T Rex?
Spinosaurus
The water-loving Spinosaurus had a spiny “sail” on its back, and a crocodile-like head, neck and tail, but was much larger than the Tyrannosaurus Rex. At 50 feet long, it’s the largest carnivore to walk (and swim) the Earth… that we know of.
What was the world like when T Rex was alive?
T. rex lived about 66–68 million years ago during the Cretaceous Period in the western United States, including Montana and Wyoming. What was the world like when T. rex was alive? Although the current landscape of Wyoming and Montana is dry and grassy, it probably resembled a Louisiana floodplain when T. rex walked the Earth.
What other dinosaurs are similar to T Rex?
Other species, such as Carcharodontosaurus, Giganotosaurus and Spinosaurus, were similar in size but lived earlier in the Cretaceous Period. They belonged to different families of predatory dinosaurs than T. rex.
What was the world’s largest city 100 years ago?
With a population of just 35,000, the ancient Egyptian city of Memphis was the world’s largest for 100 years from 2050 BC. Other Egyptian cities to feature during this early 2,000-year period included Thebes and Alexandria, which had a peak of 350,000 in 150 BC and was the largest population of any city up to 100 BC.
How much does a T Rex weigh in tons?
The Nation’s T. rex was 38 feet (11.6 meters) long, and scientists estimate that it weighed 4–5 tons, which is about 8,800–11,000 pounds. How complete is the Nation’s T. rex?
