10 Scary Things You Never Knew about Dinosaurs
We think we know everything about dinosaurs, then these facts pop up. Today we will be talking about
10 scary things you never knew about dinosaurs. Are you one of the people that think that the TRex
doesn’t deserve its title as king of dinosaurs? Wait till number one, it will probably change your mind.

Number 10. The Biggest of Them All
Dinosaurs had a rather large range in terms of size. The smallest known dinosaur, the Compsognathus,
only grew to about the size of a chicken. On the other side of the scale was the Argentinosaurus.
Amazingly, these two ends of the spectrum lived in the same time period as each other, which was
about 94 to 97 million years ago.
The Argentinosaurus not only holds the record for the biggest dinosaur, but it is also the heaviest and
longest land creature to ever live. Despite being so massive, the Argentinosaurus started off small. Their
eggs were about the size of coconuts and when they were born, they weighed a little more than 10
pounds. It took about 40 years to grow to their full size, which was about 26 feet tall, and they were 121
feet long, which is as long as three school buses. They also weighed 100 tons, which is about as much as
12 African elephants. In order to sustain their size, they would have needed 100,000 calories a day,
which is about 200 Big Macs.
Perhaps the most impressive feat this animal could do was rise up and stand on its back feet. If some
unlucky dinosaur, even huge carnivores, were to get underfoot, they’d be flattened like pancakes.

Number 9. A Vegetarian with a Bad Attitude
The Triceratops horridus, which means “threehorned face,” was a herbivore, but it still wasn’t an
animal you’d want to come across. They were 10 feet tall, 30 feet long, and they weighed four to six
tons. If it’s hard to visualize. Just think of a rhino as big as a midsized elephant, but 100 percent meaner.
Of course, the Triceratops’ most notable feature is its three horns. There were two above their eyes, and
one above their mouth. When a Triceratops reached adulthood, the horns were three feet long and
curved upwards. It was used to fight with other Triceratops over mates and territory. However, they
were also used to fight off the apex predator that lived at the same time as them – the TRex. Evidence
they would have been able to fend off a TRex was that a Triceratops fossil had a healed wound from a
TRex’s bite, suggesting the Triceratops was able to fight off the dominant predator and lived long
enough after the encounter for the bite to heal. If you were bad enough to thwart an attack from the
meanest predator around, you’re someone I wouldn’t want to mess around with.

Number 8. The Fast and the Hungry
The fastest known dinosaurs are believed to be part of a group of Theropod dinosaurs called
Ornithomimids. One of the most famous subspecies is the Gallimimus bullatus, which are the ostrichlike

dinosaurs in the first Jurassic Park movie. It’s believed that they could run 50 miles per hour. However,
given that they are toothless, they probably don’t eat meat, so this entry is not about them.

On the other hand, a dinosaur that was deffinitely fast and terrifying was the Carnotaurus sastrei, which
means “meateating bull.” It got its name because of the bulllike horns on its head, which it would have
used to bully other Carnotauruses trying to enter its territory. Also, unlike the Gallimimus, the
Carnotaurus was a pretty big animal. They were 13 feet tall, nearly 30 feet long, and weighed up to two
tons. Despite their huge size, they were surprisingly fast thanks to their massive thighs, which were up
to 15 percent of their body weight. According to calculations, they would have been able to reach
speeds of 40 miles per hour. It would be like trying to outrun a car that is driving over the speed limit on
a city street, but instead of being run over, you stand the chance of being bitten in half.

Number 7. Jurassic Park Lied to You
According to the Jurassic Park movies, Velociraptors were sixfoot tall dinosaurs that hunted in packs. As
menacing as they were on screen, they were nothing close to that in real life. While it’s highly probable
they hunted in packs, they weren’t nearly as big as they were in the movies.
