Question 1 of 10
1. Sharks have been around for the past 400 million years. Their reign over the ocean began at the end of the Mesozoic era, when they developed the features of modern-day sharks. Which was their superlative representative, an underwater terror gone extinct only 1.6 million years ago and regarded as the largest ever predatory fish? Hint


Question 2 of 10
2. The crocodile is yet another creature that sends chills up the spine when thinking about it. Despite the sheer strength and deadliness of modern-day crocodiles, they are still overshadowed by some of their ancestors, at least in regards to size. Which was one of the gargantuan crocodiles that roamed the Mesozoic, its name meaning "terrible crocodile"? Hint


Question 3 of 10
3. Perhaps the most successful group of land predators in Earth's history were the bipedal, meat-eating theropod dinosaurs. Although its reputation as a deadly hunter may have been tarnished by recent theories suggesting it was in fact a scavenger, this Cretaceous monster still endures, at least in popular culture, as the image of the ultimate carnivore dinosaur.

Answer: (two words)
Question 4 of 10
4. During the Mesozoic, the reptiles ruled both on land and underwater. While on land, meat-eating dinosaurs were the dominant predators, the seas were disputed by several distinct groups of reptiles. Out of these, the most ferocious were the serpent-like mosasaurs. Which was one of their largest and most vicious exponents? Hint


Question 5 of 10
5. While some predators rely on strength and size, others compensate by speed and agility to make exceptional hunters. And when the latter are moreover endowed with terrible weapons, like for instance sickle-shaped talons on the hind limbs, they definitely make some of the most deadly and vicious killers around. These were the Dromaeosaurid dinosaurs, generally known as the raptors. Which was one of their prominent representatives? Hint


Question 6 of 10
6. Following the extinction of the dinosaurs, the reign over the terrestrial ecosystem was taken by the mammals. Yet, nothing much changed in places like Patagonia, where bipedal creatures were still the ones to terrorize the lands with their meat-hook-like claws and massive beaks. This time round it was the giant flightless predator birds, whose best known representative was... Hint


Question 7 of 10
7. Eventually, birds became masters of the skies. Relying on surprise attacks upon unexpecting land/water targets, the large birds of prey are some of today's most efficient predators. Which was the largest eagle to have ever lived, which only went extinct 500 years ago? Hint


Question 8 of 10
8. Following the dinosaurs' good old habit of growing to immense proportions, the mammals also kept this tendency when the stage was finally set for them. Part of the Pleistocene megafauna, this creature was the largest land predator during the Ice Age in North America.
Hint


Question 9 of 10
9. Felines are the most strictly carnivorous mammals of the nine families in the order Carnivora. Extremely agile and deadly, the members of the cat family are some of the most skilled predators ever. This family also included the now extinct saber-toothed cats. Which is the most famous representative of these fierce and ferocious Cenozoic felines? Hint


Question 10 of 10
10. Although not naturally equipped with any special hunting weapon, humans are the definitive super-predators. Superior intelligence is the single, most important feature that separates humans from other predators. Which was the first hominids to organize in hunter gatherer societies, making use of hand-made crafted tools and weapons in order to become predators instead of prey. Hint

Quiz Answer Key and Fun Facts
1. Sharks have been around for the past 400 million years. Their reign over the ocean began at the end of the Mesozoic era, when they developed the features of modern-day sharks. Which was their superlative representative, an underwater terror gone extinct only 1.6 million years ago and regarded as the largest ever predatory fish?

Answer: the megalodon

Charcarodon megalodon was in many respects a king-size great white shark, as shown by recent studies. The main difference between the extinct shark and its living close relative is the size, as the megalodon's maximum size range is estimated to have been around 12-16 meters, weighting as much as 20-30 tons.
Since shark's skeletons are made out of cartilage and not bone, the fossil record for the megalodon is poor and the species is generally known from its fossilized teeth which could measure up to 168 mm (the largest yet found).
By extrapolating from the feeding habits of the modern great white shark, we can speculate that the megalodon also used the ambush tactic, delivering massive disabling bites. It is generally believed that the megalodon's diet consisted of whales, large fish and primitive pinnipeds and sirenians.
2. The crocodile is yet another creature that sends chills up the spine when thinking about it. Despite the sheer strength and deadliness of modern-day crocodiles, they are still overshadowed by some of their ancestors, at least in regards to size. Which was one of the gargantuan crocodiles that roamed the Mesozoic, its name meaning "terrible crocodile"?

Answer: Deinosuchus

Deinosuchus ("terrible crocodile") lived 80 to 73 million years ago, in the Late Cretaceous period. The physical appearance of Deinosuchus was very similar to that of modern crocodiles. The only main difference is that Deinosuchus dwarves them in regards to size: while the largest modern crocodiles reach no more than 7 meters in length, it is estimated that Deinosuchus measured between 10 and 15 meters.

Its massive size indicates that it was a top killer in its time, being capable of killing and eating even large dinosaurs.

Another amazing feature of Deinosuchus was its bite force, estimated to exceed 18000 newtons, whereas that of modern alligators (who have the strongest bite of any living animal) have been measured no higher than 9500 newtons.
3. Perhaps the most successful group of land predators in Earth's history were the bipedal, meat-eating theropod dinosaurs. Although its reputation as a deadly hunter may have been tarnished by recent theories suggesting it was in fact a scavenger, this Cretaceous monster still endures, at least in popular culture, as the image of the ultimate carnivore dinosaur.

Answer: Tyrannosaurus

Tyrannosaurus Rex has fascinated people ever since its discovery in Montana, back in 1908. A very powerful animal, T.Rex would have been a fright to any living creature: it had a large brain and keen eyesight, a strong, flexible neck, a bone-breaking bite and the famous 20 centimeter (8 inch) long teeth.

However, it was slow and its unbelievably short forearms would have been to weak to be useful for hunting. These facts made some scientists conclude T.Rex was mainly a scavenger. Contrary to popular belief, T.Rex was not the largest predator ever to roam the earth, being outmatched by dinosaurs like Spinosaurus, Giganotosaurus and probably others yet to be discovered.
4. During the Mesozoic, the reptiles ruled both on land and underwater. While on land, meat-eating dinosaurs were the dominant predators, the seas were disputed by several distinct groups of reptiles. Out of these, the most ferocious were the serpent-like mosasaurs. Which was one of their largest and most vicious exponents?

Answer: Tylosaurus

Mosasaurs were serpent-like marine reptiles who disputed their supremacy over the Cretaceous seas with sharks and plesiosaurs. Tylosaurus was among the largest of all the mosasaurs (the others being Hainosaurus and Mosasaurus), reaching lengths of over 15 meters. It was a ferocious predator who had a varied diet including fish, sharks, plesiosaurs and flightless diving birds, as it was indicated by the analysis of its stomach content. Its name means "knob lizard" and refers to its elongated snout which might have been used for ramming and stunning prey.
5. While some predators rely on strength and size, others compensate by speed and agility to make exceptional hunters. And when the latter are moreover endowed with terrible weapons, like for instance sickle-shaped talons on the hind limbs, they definitely make some of the most deadly and vicious killers around. These were the Dromaeosaurid dinosaurs, generally known as the raptors. Which was one of their prominent representatives?

Answer: Deinonychus

Deinonychus was the almost perfect killing machine of the Early Cretaceous. It was rather small (10 ft - 3 m) compared to some of its meat-eating competitors of the era, but its deadly weapons fully compensated for the size aspect. Deinonychus was built for speed and its large eyes suggest it had a good eyesight, these being essential characteristics of a successful hunter. Deinonychus also came equipped with a full slicing package: a large head and powerful jaws packed with sharp, serrated teeth, curved inside the mouth, long arms with three-fingered hands, ending in sharp talons and of course the 13cm long razor-sharp, curved claw on the second toe of each foot. Since it was among the smartest dinosaurs around, Deinonychus could use its flesh-tearing claw to kill its unfortunate prey in uniquely terrifying ways. And taking into account that Deinonychus probably hunted in packs, there was virtually no escape from its killing frenzy.
6. Following the extinction of the dinosaurs, the reign over the terrestrial ecosystem was taken by the mammals. Yet, nothing much changed in places like Patagonia, where bipedal creatures were still the ones to terrorize the lands with their meat-hook-like claws and massive beaks. This time round it was the giant flightless predator birds, whose best known representative was...

Answer: Phorusrhacos

Terror birds were an extremely successful group of predators, being the dominant predators in South America, until the continent joined with North America. Phorusrhacos stood as high as 2.5 meters and weighed approximately 130 kilograms, being one of the largest carnivorous birds to have ever existed.

A genuine "terror bird", it was equipped with meat-hook like claws and a powerful hook-tipped beak. Phorusrhacos mostly fed on small mammals and it is speculated that the bird grasped its prey with its beak and smashed it to the ground repeatedly, based on the feeding habits of its closest modern relatives - the Seriemas.
7. Eventually, birds became masters of the skies. Relying on surprise attacks upon unexpecting land/water targets, the large birds of prey are some of today's most efficient predators. Which was the largest eagle to have ever lived, which only went extinct 500 years ago?

Answer: Haast's Eagle

Haast's Eagle was the largest eagle to have ever lived, going extinct only a few hundred years ago. It lived on the South Island of New Zealand and preyed upon large flightless bird species, mainly moas. These were eventually hunted to extinction by the Maori settlers (which came to the island about 1000 years ago), causing Haast's Eagle to became extinct itself soon after. Taking into account that its main prey, the moa, weighed 10-15 times more, it is obvious that Haast's Eagle was truly a remarkable predator, striking at lighting speeds of up to 80 km/h.
8. Following the dinosaurs' good old habit of growing to immense proportions, the mammals also kept this tendency when the stage was finally set for them. Part of the Pleistocene megafauna, this creature was the largest land predator during the Ice Age in North America.

Answer: the short-faced bear

The grizzly bear is one of the largest predators today. However, its not so distant cousin, the short-faced bear, surpasses it in almost every aspect. An imposing predator, it stood as tall as 3.4 meters when standing on its hind legs and had an estimated average weight of 900 kg.

It also had an olfactory area twice as large as that of a grizzly. Analysis on its bones showed high concentrations of nitrogen-15, a stable nitrogen isotope accumulated by meat-eaters with no evidence of ingestion of vegetation. All these facts suggest that the short-faced bear was a dominant carnivore of its time, requiring about 16 kg of flesh daily in order to survive.
9. Felines are the most strictly carnivorous mammals of the nine families in the order Carnivora. Extremely agile and deadly, the members of the cat family are some of the most skilled predators ever. This family also included the now extinct saber-toothed cats. Which is the most famous representative of these fierce and ferocious Cenozoic felines?

Answer: Smilodon

Alongside the meat-eating dinosaurs, the so called sabre-toothed cats are the most amazing and fascinating predators that have ever lived. One of their best known representatives is Smilodon, which lived between 2.5 to 10,000 years ago in North and South America. Slightly smaller than a tiger, Smilodon was extremely powerful and was almost bear-like in build.

It hunted a wide range of large mammals including: bison, elks, deers, American camels, horses, ground sloths, mammoths and mastodons. Recent research that Smilodon more probably used its great upper-body strength to wrestle prey to the ground, where its long canines could deliver a deep stabbing bite to the throat.
10. Although not naturally equipped with any special hunting weapon, humans are the definitive super-predators. Superior intelligence is the single, most important feature that separates humans from other predators. Which was the first hominids to organize in hunter gatherer societies, making use of hand-made crafted tools and weapons in order to become predators instead of prey.

Answer: Homo Erectus

Homo erectus is thought to be the first hominid to hunt on a large scale. Archaeological excavations have revealed that Homo erectus developed a cooperative hunting organization and the use of fire. Sites at Torralba and Ambron, dated to 500,000 years ago, offer evidence that Homo erectus used to hunt large animals.
While larger brains facilitated the hunt, hunting and acquiring meat also facilitated growth of larger brains by providing needed high concentrations of protein and aminoacids vegetable foods didn't provide. Successful hunters provided their offspring with the nutritional needs necessary to encourage brain growth.
