According to Dr. Jordan Mallon, paleontologist and research scientist at Canadian Museum of Nature, dinosaurs had varying diets: some ate plants, some ate meat, and some ate both, but most were actually plant eaters. “If every dinosaur were a meat eater, their environment would be unable to support them,” he says.
Velociraptor (and other dromaeosaurs), Allosaurus, Giganotosaurus, Tyrannosaurus, Albertosaurusand Carcharodontosaurus had sharp teeth typical of modern flesh-eaters. They also had serrations on at least one tooth-edge.
T. rex was a very big meat-eating dinosaur, also called a carnivore. It would have been at the top of the food chain. It is known to have fed on other large dinosaurs, such as Edmontosaurus, Anatosaurus, and Triceratops, and probably could have swallowed smaller dinosaurs in a single bite.
To understand what extinct animals, such as dinosaurs, ate, we can compare their tooth types to the range of tooth types that we see with modern animals such as these carnivorous and omnivorous animals. When we look at this tiger skull, we can look at aspects of its dentition, or its teeth to understand what it ate.
The Spinosaurus is the biggest carnivore ever recorded that we know of. This mammoth dinosaur measures 50 feet in length and weighed 7 ½ tons meaning it trumps even the biggest carnivorous dinosaurs in the size stakes. It is larger than the Giganotosaurus and the infamous Tyrannosaurus Rex!
The title of largest land predator that ever walked on Earth goes to the Spinosaurus. This meat-eating dinosaur lived about 90-100 million years ago.
At a length of more than 50 feet (15 metres) and a mass of nearly 50 tons (tonnes), Megalodon was both larger and heavier than Tyrannosaurus rex.
Spinosaurus was an enormous theropod dinosaur that lived around 95-70 million years ago in the Late Cretaceous. It's the longest carnivorous dinosaur currently known, around three times the length of an African elephant and more than 20% heavier.
Dinosaurs would not have had much of a reason to eat humans. However, if they did happen to come across a human, it is likely that they would view them as potential prey.
Well, we can safely assume dinosaurs never fell prey to humans – mainly because the two never even met (despite what the Jurassic Park films suggest). Dinosaurs had already been extinct for about 62 million years by the time modern humans started roaming the planet!
rex tasted more like poultry than, say, beef or pork. Its flavor would likely have been closer to that of a carnivorous bird—perhaps a hawk—than a chicken. What does a hawk taste like? It's probably not far off from the dark meat of a turkey but would be more pungent because of its all-meat diet.
rex surely would have been able to eat people. There are fossil bite marks, matching the teeth of T. rex, on the bones of Triceratops and duck-billed dinosaurs such as Edmontosaurus, which were both over 50 times heavier than an average person. But that doesn't mean we would be hunted to extinction.
Tyrannosaurus rex craved meat so much that it ate individuals from its own species, according to new research supporting that this 35-foot-long carnivorous dinosaur from the Cretaceous Period was a cannibal.
That said, T. rex had the strongest bite force of any land animal known, even though the ancient shark Megalodon had an even more powerful chomp. It used those jaws to not only tear flesh, but also crush bone — fossilized T.
Pterosaurs are often commonly referred to as “flying dinosaurs” or “pterodactyls”, and these are the “dinosaurs” that we'll be covering today. You might have seen them in movies or pop culture, but these flying creatures were 100% real. There are currently only a handful of known pterosaurs.
So, we finally get to the world's largest carnivore, the blue whale. At a maximum size of over 90 feet, it is also the world's largest animal. Blue whales lunge through giant clouds of krill with their mouths open and then push the water they have scooped up through their baleens, swallowing the captured krill.
According to new research, dinosaurs would have lived on Earth for many more years, if a huge asteroid hadn't smashed into the planet and wiped them out.
Variables such as temperature, food sources, and oxygen levels are all factors that might impact dinosaur survival. Because dinosaurs lived in much warmer climates millions of years ago, many experts doubt they could even survive today.
T. rexes were vicious carnivores. Though the belief that they were the largest dinosaur predator has been disproven, there is no denying that they were ferocious, effective hunters. In fact, their bodies were designed for it.
Paleontologists don't know for certain, but perhaps a large body size protected them from most predators, helped to regulate internal body temperature, or let them reach new sources of food (some probably browsed treetops, as giraffes do today).
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth's climate that happened over millions of years.
It's thought that megalodon sharks became extinct in part due to climate change: as oceans grew colder, they may not have been able to regulate their temperatures as needed. Lack of prey could be behind the megalodon's extinction, as many marine animals and fish could not survive the cold temperatures.
The megalodon had a stomach volume of almost 10,000 litres, meaning it would have been capable of eating prey up to 26 feet (8 m) long. While it would have been able to chomp up a modern Orca, this means it could not swallow a T. rex whole like in 'Meg 2: The Trench'.
The T-rex would beat a Komodo dragon in a fight using its massive size advantage and powerful bite. Although unlikely, the Komodo dragon might attempt an ambush attack if it absolutely had to fight the monstrous dinosaur. It would probably not succeed in doing much damage, though.
