Type of Dino

The number of validated genera and species of extinct non-avian dinosaurs discovered and named ranges from 300 to 700. These numbers, however, do not reflect the true diversity of extinct dinosaurs due to the fact that the fossil record is incomplete, in the sense that scientists have yet to discover fossils of other kinds of dinosaurs.

Rocks for some geologic time periods are not commonly found on the surface of the Earth, which is one reason for the incompleteness of the fossil record.

Outcrops of Late Cretaceous age are more common and more widely dispersed geologically than outcrops of Middle Jurassic age, for example, many additional sorts of Late Cretaceous dinosaurs have been discovered.

What Is a Dinosaurs?

Dinosaurs existed from 245 million to the present and were primitive reptiles that lived on Earth. Since modern birds and non-avian dinosaurs share a common ancestor, they are both considered dinosaurs.

Non-avian dinosaurs had a wide range of shapes and sizes; they are now extinct. They ranged in weight from 80 to 120 tons and were almost 120 feet long. Others weighed as little as 8 pounds and were the size of a chicken. Non-avian dinosaurs were exclusively terrestrial.

Some of them may have lived in the swamps and lakes, although they did not do so entirely. Meat-eaters hunted solo or in groups and walked on two legs. Plant-eaters grazing on plants had two or four legs.

Dinosaurs had a hole in the hip socket that allowed them to walk upright, which distinguishes them from other reptiles. This characteristic was not present in pterosaurs or plesiosaurs, both of which lived in the ocean.

His findings, however, shed new insight into the strange world of dinosaurs and piqued worldwide curiosity. We’ve been fascinated by these huge reptiles ever since! We’ve learned a lot about our favorite ancient creatures throughout the years.

To learn some interesting facts about dinosaurs, let’s take a look at some of the most popular types.

Pterodactyl

When you imagine a flying dinosaur, Pterodactyl is what comes to mind. This gigantic bird-dino, which lived in Europe and Africa, was the inspiration for almost all winged dinosaurs shown in contemporary books.

We have some detrimental news for you if you’re interested in what it would be like to ride one of these creatures. Your dragon-dino was not able to take off, according to new study, because of its unusual anatomy!

Deinonychus

When over a thousand bones were discovered in 1964, the Deinonychus was originally found near Montanawithia. In the early Cretaceous epoch, it roamed what is now western North America and central Mongolia.

Sharp front claws and feathered front legs are characteristic of this extinct beast. It might help link dinosaurs to modern-day bird species by using its “arms” in a flapping motion to keep stable.

It’s a three-toed theropod, which is a carnivorous species of dinosaur.

The Deinonychus was thought to weigh about 160 pounds and be about 11 feet long. Fossils indicate that it hunted bigger dinosaurs such as Tenontosaurus, despite its modest size.

Pachycephalosaurus

The fact that Pachycephalosaurus comes with a wicked hat makes it extra cool. A bony dome crowned the skull of this dino, and it might have had decorative knobs or spikes.

The domes, like the horns of current-day rams, were believed to be used for head butting at first. The facts, however, don’t add up. Cracking domes were never intended to be built. They were most likely used to identify species or show them off. To put it another way, bone hats.

Lirainosaurus

Lirainosaurus were plant-eaters with long necks. Fresh and succulent leaves from the tops of the trees in vast green fields are easy to imagine a Lirainosaurus enjoying. They seem to have liked Spain and lived throughout Europe.

Spinosauridae

Another group of large, bipedal meat-eaters were the spinosaurids. The snouts of spinosaurids were slender and crocodile-like. Spinosaurus and Baryonyx, for example, were specialized fish-eaters in this family.

The back of Spinosaurus was covered with a large sail. It was named after the spined bones that supported it (Spinosaurus means “spine lizard”). Although not all members of the Spinosauridae family have a sail, it was named after Spinosaurus.

Coelophysis

In the late Triassic, the Coelophysis is a saurischia theropod. It’s one of the earliest dated dinosaurs. “Lizard-hipped” dinosaurs belong to the Saurischian order of dinosaurs.

To catch its prey, this theropod utilized its slender body, speed, and agility. Coelophysis was a carnivorous theropod. Little reptiles and insects were frequently eaten by it.

The Coelophysis was roughly 50 pounds in weight and measured roughly 6.6 feet in length.

Dreadnoughtus

The largest terrestrial animal to have ever walked the planet, Dreadnoughtus schrani, was discovered in Argentina. During the Late Cretaceous Epoch (100.5 million to 66 million years ago), this enormous sauropod flourished.

It was about 26 meters (85 feet) long and weighed roughly 59 metric tons (65 tons), equivalent to roughly a dozen African elephants! Its name comes from the Latin phrase “fear nothing,” and it is believed that as an adult, this herbivore had few if any predators due to its enormous size. That’s amazing!

Iguanodon

The scientists may have identified Iguanodon as the first dinosaur. Local employees found fossil teeth in a British woodland, which led to the discovery. Their suspicions were brought to Gideon Mantell, a local physician, who recognized they were not dealing with something normal.

Herbivores are thought to have existed alongside Iguanodon. These enormous dinosaurs roamed the continents of Europe, North Africa, North America, Australia, and Asia on two legs.

Their claws had fingers, which would have allowed them to chop vegetation and fight off predators. During the late Jurassic and early Cretaceous epochs, they roamed the Erath some 161.2 million to 99.6 million years ago.

Diplodocus

From the late Jurassic period, the Diplodocus was a massive sauropod. Benjamin Mudge and Samuel Wendell first discovered it in 1877 in Colorado. Barnum Brown and Henry Fairfield Osborn discovered another skeletal piece near the Como Bluffs in Wyoming in 1897.

Since then, further Diplodocus species have been discovered in the midwestern United States. Many of them can be found in museums throughout the globe.

The Diplodocus, at around 85 feet long, was a big dinosaur. It weighed a massive 12 tons, or 24,000 pounds!

Troodon

From the late Cretaceous epoch, the Troodon is a saurischia theropod.

It belonged to the genus Microraptor, a small, bird-like dinosaur with three clawed toes. This dinosaur’s egg clutches are strongly linked to birds. Their hard-shelled eggs, parental care, and female reproductive systems are all similar to those of birds.

With a massive brain and eyes, the Troodon was a lively dinosaur. Little birds, mammals, and reptiles were most likely eaten.

It grew to be roughly 8 feet long and weighed roughly 110 pounds.

Velociraptor

Velociraptors were not much larger than a turkey, standing just under 0.6 meter (2 feet) in height, contrary to what Jurassic Park would have you believe.

Their second toes, on the other hand, were still formidable predators due to their trademark large sickle-shaped claws. Humans might have struggled to repel hungry velociraptors even if they were smaller in size.

Allosaurus

About 150 million years ago, allosaurus roamed the Earth. These dinosaurs were ferocious meat-eaters with their huge jaws lined with razor-sharp teeth. The hand claws of Allosaurus were more than 1 foot long, making them even more frightening. In contrast to the T-Rex, they were sharp enough to cut!

Moreover, it might travel at speeds of 40 miles per hour! The prehistoric world’s most dangerous hunter, Allosaurus, is made up of all of these qualities!

Hadrosaurus

The Hadrosaurus was the first dinosaur found in North America, and is well-known for it. The bones of this dinosaur were found near Haddonfield, New Jersey, in 1858 by William Parker Foulke. It has been designated as New Jersey’s state fossil because of its historical significance.

The Hadrosaurus is a cerapod.

The interior of the lower teeth of a cerapod, a herbivorous dinosaur, is covered in thick enamel. Fruits, leaves, and other plants were most likely eaten by this dinosaur.

The Hadrosaurus was thought to be 25 feet long and weigh 5,000 to 9,000 pounds when it was alive.

Ankylosaurus

Ankylosaurus is a creature that seems to be too good to be true, due to its overdesigned nature. It was more brilliantly defended against predators than Stegosaurus, with spiky head and side armor, a back covered in armored plates, and a tail that ended in a massive bone club.

Imagine a rhinoceros-turtle hybrid creature. Surprisingly, until Jurassic World, the most frigid of dinosaurs did not appear in many films. And why do you know that? Whenever a T-rex confronts some unlucky Triceratops, it’s all over once the T-rex gets behind the frill. Ankylosaurus is a tough opponent to beat.

Its gigantic bony club is in your face if you get in its blind spot. With an ankylosaur, there is no fair fight.

Brontosaurus

The name Brontosaurus is derived from Greek and means “thunder lizard.” In Hollywood, these dinosaurs are well-known. In reality, this dinosaur species was depicted on postal stamps in addition to films and other forms of fiction!

The Brontosaurus was a herbivore with a small, long neck and a huge, stocky torso. In what is now North America, the various species of Brontosaurus roamed. These monsters measured about 22 feet long and weighed up to 17 tons.

Did you know that the largest elephants weigh around 6–7 tons and are up to 3.2 meters tall to give you a better idea of how big they were?

Parasaurolophus

The Late Cretaceous cerapod Parasaurolophus existed. The name Parasaurolophus means “near crested lizard.” Like other modern kinds of chameleons, this dinosaur is recognized for its enormous head crest.

It is considered to have wandered North America and parts of Asia, having been first discovered in Alberta, Canada. Parasaurolophus ate leaves, twigs, and pine needles as a cerapod, which was typically found in plants.

The Parasaurolophus weighed roughly 7000 to 8000 pounds and measured roughly 36 feet long.

Compsognathus

The remarkable sense of scale provided by the diminutive members of the genus Compsognathus is wonderful.

They had the same beautifully raptorial proportions as their tyrannosaur cousins, whirling about on their lithe back legs and snatching up smaller creatures. They were roughly the size of a turkey, though they were exponentially smaller than their tyrannosaur relatives.

Compsognathus’ bulk and Whippet-like build clearly indicate that it belongs to the bird-dinosaur transition. Compsognathus may have had protofeathers, according to a fossil of a similar species with preserved protofeathers.

Gallimimus

The adult Gallimimus weighed around 440 kilograms and was approximately 6 meters long, with big eyes on each side of a relatively small head. Gallimimus may have feathers on its body, according to scientists. Can you picture a creature with no teeth?

It’s worth noting that this one was among them! It ate by munching on its massive beak. It had no teeth. Prey and feeding were made easier by the long, slender neck. Gallimimus is a creature you may have seen before if you’re a Jurassic Park movie fan!

Europasaurus

A newly-discovered Europasaurus long-necked dinosaur. A private collector called Holger Lüdtke discovered the first remains in 1998 in Oker, Germany.

Thousands of Europasaurus bones have been discovered since 1998.

In the Late Jurassic, the Europasaurus may have been discovered as a sauropod.

Large dinosaurs with long necks, tiny heads, and four thick legs were formerly known as sauropods. The Saurischian order includes all sauropods.

The juvenile size of this dinosaur was estimated to be 5.5 feet long, while the adult size was predicted to be 20 feet long and weigh about 1,100 pounds. As a result, it was smaller than other sauropods.

Therizinosaurus

Therizinosaurs are a group of nasty late Cretaceous theropods from Asia and North America. Despite their nightmarish Freddy Krueger claws, they were most likely not carnivorous. In the front part of the upper jaw, these strange dinosaurs lacked teeth but had a tiny skull and leaf-shaped teeth.

Isanosaurus

Isanosaurus, a herbivore that originated in Asia and lived during the Triassic epoch, which spanned 250 million to 199 million years ago. Around 210 million years ago, these dinosaurs established Asia, notably Thailand. If you want to brush up on your dinosaur knowledge,

You may be interested to know that the Isanosaurus used all four legs to move around, unlike most other “lizard-hipped” dinosaurs.

Archaeopteryx

The “first bird,” Archaeopteryx, is a dinosaur.

Hermnann von Meyer found a feather from this species in Germany in 1860, and a skeleton was found in 1861. Feather fossils have subsequently been discovered in abundance.

As a theropod, it was carnivorous and potentially ate tiny reptiles, mammals, and insects. Although very little is known about its particular diet.

During the late Jurassic era, Archaeopteryx was a tiny theropod dinosaur. The largest species didn’t grow much bigger than two feet.

Mosasaurus

Were dinosaurs able to swim? Of course! It’s only natural that dinosaurs lived in the ocean since they were discovered to roam over all lands.

One of the water reptiles that has become extinct is Mosasaurus. The lizard, sometimes known as the Meuse Lizard or the Meuse River Lizard, lived about 66 to 70 million years ago and was a carnivore.

These ancient fish dinosaurs, according to experts, avoided deep oceans and stayed on the surface of the water because to their barrel-shaped bodies and poor vision. Mosasaurus may grow to be as long as 17 meters in length!

Dilophosaurus

The two crests that sit on top of the head of the dilophosaurus are a characteristic of this theropod. It was named after a two-crested lizard that lived in North America during the early Jurassic period and had its first fossils discovered in northern Arizona in 1940.

Throughout the early Jurassic epoch, Dilophosaurus was the biggest known dinosaur.

It had a slender build, despite its large size. It seems to have hunted bigger herbivore dinosaurs because of its sleek body and strong legs.

The dilophosaurus measured roughly 23 feet in length and weighed roughly 900 pounds.

Tyrannosaurus Rex

Tyrannosaurus Rex is without a doubt the most well-known dinosaur. It’s worth noting that “Tyrannosaurs” is essentially a term meaning “tyrant lizard king.” The T-Rex is now widely recognized as a carnivore, after having been represented in various forms of media.

This dino’s prey most likely delighted it as it chased after it and ultimately ate its meal with its comically tiny arms and jaws. Most artists have portrayed it in this way.

Our favorite T-Rex, though, may have feathers all over its body, according to new research. What would a 40-foot terrifying bird look like with feathers?

Plesiosaurus

Plesiosaurus wasn’t a dinosaur, it was a marine lizard. It’s commonly mistaken with a water dinosaur.

In the early Jurassic epoch, dinosaurs roamed the earth, but aquatic reptiles ruled the seas. Fish and other aquatic reptiles were the prey of these predators.

They are not part of the Saurischian or Ornithischia orders because they are not technically dinosaurs.

In 1823, early paleontologist Mary Anning described the first complete skeleton.

Plesiosaurus have turtle-like bodies and a long neck. It had a broad body and flipper-like arms, despite the fact that it did not have a shell. They could reach a height of 49 feet and weigh between 1,100 and 1,300 pounds.
