Q. What is the name of the supercontinent that means all earth?
Pangaea
Q. Did Pangea happen before dinosaurs?
At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.
Q. What was the strongest dinosaur?
Q: Which dinosaur was the strongest? A: The strongest was probably the biggest, ultrasauros, who was six-stories high. Or, among meat-eaters, T. rex.
Q. What was the biggest baddest dinosaur?
Spinosaurus
Q. Was Spinosaurus bigger than T Rex?
Known as Spinosaurus, the colossal predator sported a massive finlike sail on its back and a 3-foot-long (0.9 meters) jaw full of jagged teeth. Bigger than both T. rex and Gigantosaurus, it lived in the swamps and rivers of North Africa during the Cretaceous Period, about 112 million to 97 million years ago.
Q. What can beat at Rex?
A Tyrannosaurus Rex might be known for its ferocious bite, but now scientists say a caiman that lived eight million years ago, had a bite TWICE as powerful. Known as Purussaurus brasiliensis, the reptilian predator lived in the Amazon region in South America.
Q. What do T Rex use arms for?
T. Rex used its arms to clutch tightly onto squirming prey before it delivered a killer bite with its jaws. (This dinosaur’s powerful arm muscles lend further credence to this idea, but once again, we can’t adduce any direct fossil evidence for this behavior.)
Q. Why did T Rexes 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.
Q. Why do carnotaurus have small arms?
As fearsome as Carnotaurus looked, though, it’s hard not chuckle at the dinosaur’s arms—the hand and lower part of the forelimb were so reduced in size that some paleontologists have viewed them as vestigial structures that have almost entirely lost their ability to function in acquiring prey.
Q. Why did theropods have small arms?
According to Steven Stanley, a paleontologist at the University of Hawaii at Manoa, T. rex arms were used to slash prey in close proximity to the dinosaur. And the short arm length was actually more beneficial for slashing, considering the size of T. rex’s head.
