1. When did the Therizinosaurids live?

From Quiz The Long Arm of the Claw

Answer: Cretaceous

The Therizinosaurids all lived during the Cretaceous period, from the middle of the Early Cretaceous up to the end of the Late Cretaceous.

From Quiz Weirdosaurus Rex Returns

Answer: Gargoyleosaurus

Gargoyleosaurus, the gargoyle lizard, was discovered in western North America in the Morrison Formation and dated to about 155 million years ago. (For comparison purposes, most known ankylosaurs lived during the Cretaceous.) Unlike later ankylosaurs, it had teeth on its upper jaw and its armor was hollow. The holotype skeleton resides at the Denver Museum of Nature and Science.

From Quiz When Dinosaurs Ruled the Earth

Answer: Coelophysis

Coelophysis was a slender and small dinosaur that grew to lengths of 3 meters. While tiny compared to most dinosaurs and other fauna, it proved successful in the time of the Triassic. They have been depicted in pop culture, most famously being one of the first dinosaurs featured in BBC's 'Walking with Dinosaurs' to represent the arrival of a new breed of reptiles, for supremacy of the planet.

From Quiz Weirdosaurus Rex

Answer: Medusaceratops

Medusaceratops is of many ceratopsids (Triceratops-like dinosaurs) that lived in what is now western North America during the Cretaceous period. It was originally mistaken for the similar-looking Albertaceratops. The realization that it was a different dinosaur caused the creation of the "Medusaceratops" genus. The holotype is classified as Medusaceratops lokii ("Loki's horned-faced Medusa"). It's a reference to the snakelike horns along its frill as well as the fact that it stymied scientists when first discovered.

From Quiz Once a terrible lizard...

Answer: Coelophysis

The name "Coelophysis" is derived from two Greek words: "Koilos", meaning "hollow" and "Physis", meaning "form". The name refers to the structure of its limb bones. Coelophysis was one of the earliest dinosaurs. The genus has also been referred to as Longosaurus and Riobarrasaurus, while the genus Megapnosaurus is now considered synonymous with Coelophysis.

From Quiz Dinosaurs: Carnivores

Answer: Archaeopteryx

Archaeopteryx is the first known flying bird, but it would not have been a very efficient flyer because of its primitive skeleton and long tail. The chick of the hoatzin bird, which lives in Venezuela and Guyana, has claws on each wing that are very similar to archaeopteryx's. It uses them to climb and cling onto trees.

From Quiz The Very Vicious Velociraptor

Answer: Cretaceous

Velociraptors lived in the late Cretaceous Period, about 71 to 75 million years ago. It was a part of the Mesozoic Era and the Phanerozoic Eon.

From Quiz The Dinosaur Proficiency Test

Answer: Their complex brains

Amazingly, the part of the brain in Troodon devoted to thought processes is huge, more developed than any other dinosaur. Aside from that, it had the highest brain-body ratio of any dinosaur as well as one of the most well-developed occipital lobes, or the part that had to do with visual information processing. This means that Troodon could well have the ability to see well in the dark.

From Quiz The King of the Dinosaurs

Answer: North America

The first T-Rex fossils were a partial skeleton found by Barnam Brown in Wyoming in 1900, and then in Montana in 1902.

From Quiz Dinosaur Etymology

Answer: Carcharodontosaurus

Carcharodontosaurus, at 43 feet was larger than the famed T.Rex.

From Quiz Fossils and Dinosaurs

Answer: Albertosaurus

The Albertosaurus was much like the Tyrannosaurus Rex, although it was slightly smaller.

From Quiz Dinosaur Nomenclature

Answer: Double Beamed

The prefix 'di' is a Greek word that means 'two'. The suffix 'docus' is from the Greek word dokos, meaning 'beam, bar, or shaft'. Diplodocus is so named because its neck and tail are so long.

From Quiz Pterosaurs: Rulers of the Sky

Answer: Winged Lizard

The name 'Pterosaur' comes from the Greek words 'Pteron' (wing) and 'Sauros' (lizard.)

From Quiz Dinosaur Ages

Answer: Cretaceous Period

There were no dinosaurs in the Permian. The Triassic didn't host any sauropods, and Saltasaurus is a weird sauropod, due to the fact that it existed one age too late to see his big brothers.

From Quiz Dinosauria

Answer: Mesozoic

The dinosaurs roamed the Earth for about 185 million years (over ninety times longer than us humans have ruled the planet). The Mesozoic Era is divided into the Triassic (250-206 mya), the Jurassic (206-144 mya) and the Cretaceous (144-65 mya). During this whole period, dinosaurs were masters of the land and at the same time, reptiles also ruled the seas and the skies.

From Quiz Dinosaurs - Missing Links

Answer: Plateosaurus

Saurischia -> Sauropodomorpha -> PROSAUROPODA This group consisted of large herbivores that may have had the same ancestors as the sauropods. Prosauropods lived from Late Triassic to Early Jurassic and they were spread throughout the world.

From Quiz When Dinosaurs Roamed The World

Answer: Permian

The Dimetrodon was a sail-backed reptile.

From Quiz 9 for 10 - Dinosaurs

Answer: Triceratops

The Triceratops is believed to have existed during the late Cretaceous period around 68 million years ago. First discovered near Denver, Colorado in 1887, the Triceratops has had several remains found in the Western parts of Canada and the United States including the Hell Creek Formation, Denver Formation, Laramie Formation, and Evanston Formation. With three horns on its head, it is believed that the horns served two purposes; combat and courtship. As they were low lying creatures, it is believed that they were herbivores and fed off of the low ground on small plants or shrubs. As one of the more popular and well known dinosaurs, they have been used in many pop-culture features including the popular film "Jurassic Park" and BBC documentary "Walking with Dinosaurs".

From Quiz The Long Arm of the Claw

Answer: one metre

At one metre long, the claws of Therizinosaurus are the longest of any known animal.

From Quiz Weirdosaurus Rex Returns

Answer: Pantydraco

Dug up in Pant-y-ffynnon, Wales, Pantydraco is a sauropodmorph from the Triassic era. It was originally classified as a Thecodontosaurus but reclassified as its own genus. Pantydraco grew to about the size of an adult human and its low center of mass suggests it was bipedal. Pantydraco appears to have traits of both carnivores and herbivores, and is thus believed to have been omnivorous.

From Quiz Weirdosaurus Rex

Answer: Geminiraptor

Celina and Marina Suarez are twins you say? That'd explain why the dinosaur they discovered in Utah in 2010 was named Geminiraptor. Only a part of the jaw was discovered. It was enough to classify the dinosaur as a troodontid (kind of like Velociraptor but smaller and sleeker), but not enough to give a clear idea of where it belonged on the troodontid lineage tree. Geminiraptor is the first dinosaur of its kind known to have lived during the Cretaceous period in North America.

From Quiz If Dinosaurs Could Talk, part two

Answer: Struthiomimus

The first complete Ornithomimid to be discovered, Struthiomimus was named by Henry Fairfield Osborn in 1917. Although classed as Theropods, Ornithomimids had no teeth and this has raised considerable debate about their feeding habits. The most widely-accepted view is that they fed on insects, lizards and small mammals.

From Quiz Once a terrible lizard...

Answer: Diplodocus

The name "Diplodocus" is a neo-Latin expression which combines two Greek words: "diplos" meaning "double" and "dokos", meaning "beam". The name was coined by paleontologist Othniel Charles Marsh in 1878, one year after the discovery of the first diplodocus fossils. The name was chosen because of the double-beamed form of the chevron bones located behind the dinosaur's tail.

From Quiz Dinosaurs: Carnivores

Answer: Carnotaurus

The eyebrow 'horns' of carnotaurus are a puzzling feature. They do not seem large or strong enough to be weapons, and in any case, this dinosaur was already a very large and powerful creature. The horns may have grown with maturity, indicating that the owner was adult and able to breed.

From Quiz Dinosaurs for Dummies

Answer: Three-horned face

The Triceratops had three horns on its face and a frill around its neck/back of the head. This 30 foot (9 metre) species was a plant eater.

From Quiz The Very Vicious Velociraptor

Answer: Mongolia

It was found during an American Museum of Natural History expedition in the Gobi Desert. The area it was found in is known as the Flaming Cliffs. The fossil was complete, although the skull was crushed.

From Quiz Dinosaurs for Dummies

Answer: Mesozoic

The Mesozoic Era is broken down into three periods: the Triassic, Jurassic and Cretaceous. The era spans the period from around 252 million years ago to 66 million years ago and is sometimes known as the Age of Reptiles. The Paleozoic Era started around 541 millions years ago and immediately preceded the Mesozoic Era. The Proterozoic Eon preceded the Paleozoic Era and the Cenozoic Era took over from the Mesozoic Era and runs to the present day.

From Quiz The Dinosaur Proficiency Test

Answer: They are smaller

As there are far less resources on islands compared to the mainland, dinosaurs had to get smaller to compensate for less food. Fossils have been found of titanosaurs barely 7m long compared to their 25m long relatives. Studies have shown that these dwarf sauropods were all adults and the area which they had died 85 million years ago had once been an island.

From Quiz Dinosaurs or Dragons? Faulty Fossil Findings

Answer: Apatosaurus

Othniel Charles Marsh, a Yale University professor, first discovered the bones of a nearly complete apatosaurus in 1877. In 1879 he then discovered what he thought was a new species of Sauropod and called it "Brontosaurus", meaning "thunder lizard". It was later discovered that the apatosaurus was actually just a juvenile brontosaurus, and thus the brontosaurus was renamed to apatosaurus as it was the first to be named. Also, the skull that was put on the brontosaurus actually belonged to that of the camarasaurus, another Sauropod. In 2015, a study completed by Emanuel Tschopp, Octavio Mateus, and Roger Benson concluded that the brontosaurus was separate to the apatosaurus and should be treated as a distinct genus. While this has some support, the matter is not conclusive, with other palaeontologists such as Michael D'Emic critiquing the conclusion. The apatosaurus was a herbivorous sauropod from the Jurassic Period. Weighing in at about 23 000 kilograms (25 short tons) and with a length of about 23 metres (74 feet), it was one of the biggest land animals to ever walk the Earth. Its name comes from the Greek words "apatelos" (meaning "deceptive") and "sauros" (meaning lizard), so named because its chevron bones were similar to those of ancient marine reptiles known as mosasaurs. The other three dinosaurs were also Sauropods but did not cause the brontosaurus confusion.

From Quiz The Dinosaurs of "Jurassic Park"

Answer: a bony shield

In addition to its three horns, Triceratops also had a wide, bony shield that stretched over the back of its neck. It would probably have been quite difficult for a predator, such as Tyrannosaurus Rex, to fit its large head behind the shield.
