The first scientifically recognized dinosaur egg fossils were discovered in 1923 by an American Museum of Natural History crew in Mongolia.
How did T rex become extinct?
The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some 65.5 million years ago. For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaurs’ food supply.
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 T rex a dinosaur?

Is Spinosaurus related to crocodiles?
It was Spinosaurus aegyptiacus, a 50-foot long creature with powerful jaws and a solid, spiny sail on its back that dwelled in Northern Africa 95 million years ago.

Spinosaurus was larger than both T. rex and Giganotosaurus, which was previously the largest carnivorous dinosaur known.
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.
Why are ostrich eggs so big?
In most birds and reptiles, an egg is the zygote, resulting from fertilization of the ovum. It nourishes and protects the embryo. The 1.5 kg ostrich egg contains the largest existing single cell currently known, though the extinct Aepyornis and some dinosaurs had larger eggs.
Can ostriches kill you?
An ostrich’s powerful, long legs can cover 10 to 16 feet in a single stride. These legs can also be formidable weapons. Ostrich kicks can kill a human or a potential predator like a lion. Each two-toed foot has a long, sharp claw.

Adult
Female: 1.7 – 2 m

Did dinosaurs have hearts?
Both modern crocodilians and birds, the closest living relatives of dinosaurs, have four-chambered hearts, although modified in crocodilians, and so dinosaurs probably had them as well. However such hearts are not necessarily tied to metabolic rate.
Are dinosaurs warm or cold blooded?
Dinosaur researcher Michael D’Emic analyzes dinosaur bones. Dinosaurs were once thought to be the cold-blooded kings of the Mesozoic era. But new research on their growth rates suggests the prehistoric beasts grew just as fast as mammals, indicating they were warm-blooded creatures.
Did all dinosaurs have feathers?
Almost all dinosaurs were probably covered in feathers, Siberian fossils of a tufted, two-legged running dinosaur dating from roughly 160 million years ago suggest. Over the past two decades, discoveries in China have produced at least five species of feathered dinosaurs.
