1.
What dinosaur is considered the first true bird?
Correct Answer
A. Archaeopteryx
Explanation
Archaeopteryx is considered the first true bird because it possesses both reptilian and avian characteristics. It had feathers, wings, and a bird-like beak, but also retained reptilian features such as teeth, a long bony tail, and claws on its wings. These characteristics make it a transitional fossil, providing evidence for the evolutionary link between dinosaurs and birds. Its discovery in the late 19th century was significant in supporting the theory of evolution and understanding the origins of birds.
2.
Which dinosaur was the longest of them all?
Correct Answer
D. Diplodocus
Explanation
Diplodocus is believed to be the longest dinosaur of all time. It was a herbivorous dinosaur that lived during the Late Jurassic period. Diplodocus had a long neck and tail, reaching lengths of up to 90 feet. Its long, slender body allowed it to efficiently browse for vegetation. Its small head, with a tiny brain, was positioned high above the ground, enabling it to feed on tall trees. Diplodocus also had a whip-like tail that it could use for defense against predators. Its length, combined with its unique body structure, makes Diplodocus the most likely candidate for the longest dinosaur.
3.
What kind of dinosaur ran on two legs?
Correct Answer
C. T-Rex
Explanation
Among the options provided, the Tyrannosaurus Rex (T-Rex) is the correct answer as it is well-known for being a bipedal dinosaur, meaning it ran on two legs. The T-Rex is perhaps the most famous of all dinosaur species, characterized by its massive body, sharp teeth, and dynamic posture, indicative of its two-legged movement.
4.
Which of these dinosaurs had very short front legs compared to its back legs?
Correct Answer
D. Diplodocus
Explanation
Diplodocus is the correct answer because it is a long-necked dinosaur known for its long and slender body. It had very short front legs compared to its back legs, which is evident from its skeletal structure. This adaptation allowed Diplodocus to graze on vegetation at ground level while its long neck reached higher branches.
5.
What meat-eating dinosaur is known for having really bad breath?
Correct Answer
B. Tyrannosaurus Rex
Explanation
The Tyrannosaurus Rex is infamous not only for its size and predatory habits but also, hypothetically, for having bad breath, which is a facet often mentioned in popular culture and scientific conjecture. This idea stems from the T-Rex's diet of raw, often decaying meat, which likely caused a buildup of bacteria in its mouth, leading to less-than-fresh breath.
6.
What does Tyrannosaurus Rex mean?
Correct Answer
B. Tyrant Lizard King
Explanation
Tyrannosaurus Rex means "Tyrant Lizard King." This name reflects the characteristics of this dinosaur, as it was a large and powerful predator with a dominating presence. The term "tyrant" suggests its fierce and intimidating nature, while "lizard king" refers to its classification as a reptile. This name accurately portrays the dominant and fearsome nature of the Tyrannosaurus Rex.
7.
Where will you find a real skeleton of a Tyrannosaurus Rex?
Correct Answer
B. At field museum In Chicago
Explanation
The correct answer is "At Field Museum In Chicago." The Field Museum in Chicago is known for its extensive collection of natural history artifacts, including a real skeleton of a Tyrannosaurus Rex. The museum houses one of the most complete and well-preserved T. Rex specimens ever discovered, named "Sue." Visitors can see the skeleton on display and learn about the fascinating history and biology of this iconic dinosaur.
8.
Which of these dinosaurs had really short front legs that looked like little arms?
Correct Answer
A. Tyrannosaurus Rex
Explanation
Tyrannosaurus Rex had really short front legs that looked like little arms. This is a well-known characteristic of this dinosaur, as depicted in various movies and illustrations. The short front legs of Tyrannosaurus Rex were not used for walking or supporting its massive body, but rather for grasping prey or objects.
9.
What is the nickname of the T-Rex skeleton that was discovered by Sue Hendrickson?
Correct Answer
B. Tyrannosaurus Sue
Explanation
Tyrannosaurus Sue is the correct answer because it accurately identifies the nickname of the T-Rex skeleton discovered by Sue Hendrickson. The name "Sue" refers to the paleontologist who found the skeleton, while "Tyrannosaurus" is the species to which the skeleton belongs. Therefore, "Tyrannosaurus Sue" is the appropriate nickname for this particular T-Rex skeleton.
10.
How much did a full-grown T-Rex weigh?
Correct Answer
D. 7-8 Tons
Explanation
A full-grown T-Rex weighed around 7-8 tons. T-Rex was one of the largest carnivorous dinosaurs that ever existed, with a length of about 40 feet and a height of about 15 feet. Its massive size and weight were necessary to support its powerful muscles and enable it to hunt and feed on large prey.
11.
What is the largest dinosaur to be discovered in South America?
Correct Answer
C. Giganotosaurus
Explanation
Giganotosaurus is the correct answer because it is known to be one of the largest dinosaurs ever discovered in South America. It lived during the Late Cretaceous period and is estimated to have been around 40 to 46 feet long and weighed up to 8 tons. Its size and weight make it larger than other dinosaurs like Pterodactyl, Velociraptor, and Brachiosaurus, which were not as large as Giganotosaurus.
12.
Before its name was changed to Apatosaurus, what did we call this dinosaur?
Correct Answer
B. Brontosaurus
Explanation
Before it was officially recognized as Apatosaurus, this dinosaur was commonly known as Brontosaurus. The name change is a result of a long-standing mix-up in paleontology that began in the late 19th century. In 1877, the first Apatosaurus fossils were discovered, and two years later, more complete fossils were found and mistakenly classified under a new name, Brontosaurus. Later research determined that both specimens belonged to the same genus, Apatosaurus, which had naming priority as it was named first.
13.
What giant dinosaur was so big it was able to eat the huge Argentinosaurus?
Correct Answer
B. Giganotosaurus
Explanation
Giganotosaurus is the correct answer because it was a giant dinosaur that was capable of eating the huge Argentinosaurus. Giganotosaurus was one of the largest carnivorous dinosaurs and had a size and strength that allowed it to prey on large herbivorous dinosaurs like the Argentinosaurus. Its large size and powerful jaws would have made it possible for Giganotosaurus to successfully hunt and consume such a massive prey.
14.
What would happen when an Allosaurus lost a tooth?
Correct Answer
C. It grew a new tooth.
Explanation
When an Allosaurus lost a tooth, it grew a new one. This is a common phenomenon in many reptiles, including dinosaurs. Reptiles continuously replace their teeth throughout their lives, as they wear down or fall out. This process is known as dental replacement or tooth regeneration. Therefore, when an Allosaurus lost a tooth, it would naturally grow a new one to replace it.
15.
During what Era did dinosaurs become extinct?
Correct Answer
C. Mesozoic Era
Explanation
The Mesozoic Era is the correct answer because it is widely known as the "Age of the Dinosaurs." This era, which lasted from about 252 million years ago to 66 million years ago, saw the rise and dominance of dinosaurs on Earth. It is during the Mesozoic Era that dinosaurs evolved, diversified, and eventually became extinct, most likely due to a combination of factors including a large asteroid impact and volcanic activity. Therefore, the Mesozoic Era marks the end of the dinosaur's reign on Earth.
