11 Interesting Prehistoric Species

"Dinosaurs are believed to have been highly intelligent creatures with exceptional senses. Learn interesting facts about these extinct creatures."

Dinosaurs  and other prehistoric creatures have always been a fascinating topic for kids and adults. They are part of our history, but how much do you really know about them? Do you know which ones were the largest or most dangerous? Which ones could fly and which could swim? 

Here are some interesting prehistoric beasts and some fascinating information about them.


The Pterodactyl lived during the late Triassic period, which occurred around 230 million years ago. It was a carnivore, meaning it ate meat and was also a reptile. The Pterodactyl had wings and could fly, making it an incredibly powerful predator.

With its long tail and powerful legs, this flying reptile was one of the first creatures to take to the skies after evolving from land animals. The Pterodactyl is not related to birds in any way; they are actually distant cousins of dinosaurs, such as Tyrannosaurus rex and Allosaurus.

The Pterodactyl was, by all accounts, a very large creature. It had a wingspan of about 33 feet, and it stood about 16 – 19 feet tall. Sir Richard Owen gave the Pterodactyl its name in 1841. He based his name on the Greek words pteron and daktylos, which mean “winged lizard.”

The diet of the Pterodactyl is primarily comprised of fish and small mammals, including bats and mice. It had a beak-like mouth that was used for crushing bones. It had no teeth, so it would swallow its food whole and then use its tongue and digestive system to break down the food into nutrients.

The Pterodactyl had large wings that allowed it to fly through the air and hunt for prey. Its body was covered with feathers that helped keep it warm during cold nights or when flying at high altitudes.

The Lirainosaurus lived in the Cretaceous period, which lasted from 145 million to 66 million years ago. It was roughly 32 feet long and probably weighed about 20 tons. It had small arms with three fingers on each hand.

The diet of the Lirainosaurus has been a topic of debate among paleontologists for quite some time. The most recent research suggests that this dinosaur was a herbivore, but it is possible that at least one species of Lirainosaurus was omnivorous.

The first thing to consider when examining an animal’s diet is its teeth. For example, carnivores have sharp, pointed teeth designed to tear flesh from their prey; herbivores have flat molars built for chewing plant matter; and omnivores have both types of teeth, depending on what they eat.

The second thing to consider is the size and shape of the skull. Carnivores tend to have long snouts with large brains to process their prey’s meat and bone; herbivores tend to have shorter snouts with smaller brains because they don’t need as much processing power, and omnivores have a mixture of both long and short snouts depending on what they eat most frequently.

The Iguanodon is an extinct genus of ornithopod dinosaurs that lived in the late Jurassic period (about 152 million years ago). The name iguanodon means “iguana tooth” and was coined by English paleontologist Richard Owen in 1841, who mistook its teeth for those of a giant lizard.

It was not a true iguana, but it was similar in appearance to modern-day lizards. It had a long body, short legs, and a small head with large eyes. It also had powerful jaws and teeth that helped it chew plant material such as ferns and cycads.

The Iguanodon could reach up to 9 feet tall and weigh more than 4 tons. It was a herbivore, meaning it ate only plants. The Iguanodon’s body was covered with thick, scaly skin that helped protect it from predators such as Tyrannosaurus rex and Giganotosaurus Carolinii. It also had a large tail that could be used as a weapon against predators or other hostile dinosaurs like Velociraptors. While there have been some indications of carnivory in some specimens, it is believed that these were due to injuries or other factors such as illness.

The Allosaurus lived during the Late Jurassic period, which lasted from 145 to 150 million years ago. It was the largest meat-eating dinosaur in history. It measured up to 38 feet long and weighed up to 3 tons.

The Allosaurus had a long, low-slung body and long, muscular legs. It had a large head with massive jaws. It also had a thick tail that made up about half of its total length. The Allosaurus was a large, carnivorous Saurischian dinosaur. It had relatively short arms with three-fingered hands and powerful jaws filled with sharp teeth for ripping flesh from its prey.

Its diet consisted primarily of large dinosaurs (sharing the same habitat), such as Apatosaurus, Diplodocus, and Camarasaurus. However, it also ate smaller animals like small reptiles, mammals, and birds.

The Brontosaurus lived during the late Jurassic period, around 150 million years ago. The Brontosaurus was a herbivorous dinosaur with a very long neck and tail, and its name means “thunder lizard” in Greek.

The Brontosaurus is thought to have been about 80 feet long and 45 feet tall. It weighed between 30 and 35 tons, making it one of the largest animals that ever lived. It had a very long neck and tail, which made up about 90% of its body length.

It is believed that the Brontosaurus was herbivorous and fed on low-growing plants such as ferns and conifers. It had peg-like teeth, which were used for grinding plant material. The teeth were also used to grasp branches while feeding. The Brontosaurus was mostly a vegetarian, but it may have also eaten insects or small animals.

The Gallimimus lived during the Cretaceous Period, which lasted from 145 million to 65 million years ago. It was one of the largest dinosaurs of its time. It weighed around 1,000 pounds and could grow up to 30 feet long and 7 feet tall. Its tail was very long and thin, which helped it balance when running at high speeds. Gallimimus lived in herds, which would have been quite noisy as they ran across the grassy plains of Mongolia in search of food.

The Gallimimus was a herbivorous dinosaur, meaning that it ate only plants. It has been found in the same fossilized remains as the Brachiosaurus and the Apatosaurus, both of which are herbivores. These three dinosaurs were found together, indicating that the Gallimimus had a similar diet to its relatives.

The Isanosaurus lived during the Early Jurassic period, which lasted from 199 to 183 million years ago. It was a member of the Prosauropoda, a group of dinosaurs that were among the earliest sauropsids, a category that includes both reptiles and birds. The prosauropod dinosaurs were generally small, with long tails and relatively short necks.

The Isanosaurus was around 22 feet long and weighed up to 2 tons. It was a bipedal dinosaur, meaning it walked on two legs, like us humans do. It had long hind limbs that were slightly longer than its forelimbs to move quickly through the trees. The Isanosaurus also had strong claws on its hands and feet to climb trees easily.

The Isanosaurus’ diet was based around the coniferous plants that grew in its environment at the time. These plants had seeds rich in oil, which made them high-energy snacks for this dinosaur.

The Mosasaurus lived during the Cretaceous period, as did its cousin, the Plesiosaur. The Mosasaurus was a large sea monster, reaching lengths of up to 56 feet and weighing 15 tons. It hunted fish and other marine animals by swimming at high speeds and snapping its jaws closed on prey. The Mosasaurus’s diet included smaller marine reptiles like Plesiosaurs.

The Mosasaurus was a large aquatic reptile that was discovered in the 19th century. The Mosasaurus was one of the largest animals on Earth during its time. Its name comes from Mosa, which means “Meuse River” in Greek, and Saurus, which means “lizard.” It had a long body with a streamlined shape that helped it swim fast in the water. It also had flippers for swimming and sharp teeth for catching fish.

The Diplodocus lived in the Jurassic period (199 million years ago to 145 million years ago). It was a long-necked dinosaur that was about 85 feet long and weighed about 30 tons (there are reports of a few that weighed as much as 80 tons). It was one of the largest animals to have ever lived. The name “diplodocus” means “double beamed” and refers to its double-beam vertebrae.

The Diplodocus was known as a sauropod, meaning it’s a long-necked dinosaur with a small head and tail. It was a herbivore, which means that it ate only plants. Although there are many theories about what its diet may have been, no one knows for sure what the Diplodocus ate. Scientists believe they may have eaten leaves and ferns, but they also believe that they may have been opportunists who would eat whatever they could find.

Tyrannosaurus Rex

The Tyrannosaurus Rex was said to live during the late Cretaceous period (67 million to 66 million years ago). It was one of the largest meat-eating dinosaurs to have ever lived. It was an apex predator, meaning it had no natural predators, and it could reach lengths of up to 40 feet long and weigh in at 6 tons.

Its teeth were approximately 5 inches long, and its legs were nearly 10 feet long. It also had relatively small arms compared to its size, making it more maneuverable than other large dinosaurs.

The Tyrannosaurus Rex is believed to have had a diet that consisted primarily of other dinosaurs. Its name means “tyrant lizard king.” Scientists have found evidence of T-Rex teeth on fossils from ceratopsian dinosaurs such as Triceratops and Torosaurus and sauropods like Diplodocus or Apatosaurus. They also found traces of carbonized plant matter in other dinosaur fossils that likely belonged to these carnivores.

The Styracosaurus was a Ceratopsian that lived during the Late Cretaceous period, also known as the Mesozoic Era. The Cretaceous Period began 145 million years ago and ended 75 million years ago. This dinosaur’s type species was named in 1884 by Othniel Charles Marsh based on fossils found in Wyoming and Colorado.

The Styracosaurus was not a large dinosaur, but it was still large enough to be considered a herbivore. It weighed an estimated 3 tons and stood 6 feet tall. This means that the Styracosaurus had a body length of about 18 feet.

It was one of the largest Ankylosauridae dinosaurs known to have lived. It lived alongside other dinosaurs like the Triceratops and Tyrannosaurus rex. The Styracosaurus was smaller than these dinosaurs, but it still had impressive horns on its head and spikes on its back which made it look larger than it really was.

These horns were used for fighting with other males over territory or females during mating season; however, they were also used as protection against predators such as Allosaurus or Tyrannosaurus rex.

The styracosaurus is believed to have had a herbivorous diet. It is thought that it had a large gut, which would have allowed it to eat plants and digest them in a short amount of time. The Styracosaurus had a toothless beak, allowing it to eat many different plants. It was also thought to be able to chew its food before swallowing it, which would help it digest the food better.
