Dinosaurs have always been a source of human fantasies. From children to experienced adults, these ancient animals have pulled the generations together. Paleontologists have found close to 300 genera and more than 700 species of dinosaurs from the Triassic, Jurassic, and Cretaceous, but only a few species have attained household names. Why? The reason for this may be attributed to their appearances in movies, documentaries, museums, and, not least, in popular culture, among other fascinating physical characteristics.
The following takes a look in depth at 10 of the most popular dinosaurs, with their description, some interesting facts, and an insight as to why they would continue being outstanding.
1. Tyrannosaurus Rex
The Tyrannosaurus rex is generally described as the most famous dinosaur ever found, often referred to as the “king of the dinosaurs.” Since it has starred in movies such as Jurassic Park, due to its fearsome appearance, and since its name, in Greek, means “tyrant lizard king,” it has turned out to be a symbol of prehistoric life. T. rex lived during the late Cretaceous period, approximately 68 to 66 million years ago.
Fully grown, T. rex was about the length of an average school bus-43 feet-and had a huge skull full of sharp teeth. The beast weighed in at about 7.5 tons, heavier than an adult African elephant. Paleontologists theorize that T. rex, despite its enormous size, may have attained running speeds of as much as 20 miles an hour. Its fossils are found in places like the United States and Canada, basically in Montana and South Dakota, where the complete T. rex specimen, named “Sue,” is being housed in the Field Museum in Chicago.
Fun Fact: The estimated bite force of T. rex is said to be the strongest for any land animal that has ever existed—capable of crushing bones with a single bite.
2. Triceratops
Another well-known dinosaur with three peculiarly distinctive facial horns and a large bony frill is Triceratops. It lived in North America during the late Cretaceous period, roughly 68-66 million years ago. The name means “three-horned face” in Greek. Despite its formidable horns, the Triceratops was a docile plant-eater that likely used its horns against predators, like T. rex, and during courtship displays to attract mates.
Reaching as long as 26 feet, as high as 10 feet, and weighing as much as 12 tons, the Triceratops was a giant among the herbivores of his time. Triceratops fossils are found in large numbers, particularly in regions such as Montana, South Dakota, and Wyoming, where it is recognized as the official state dinosaur.
Fun Fact: Triceratops is the state fossil of South Dakota and Wyoming’s official dinosaur.
3. Velociraptor
The Velociraptor is probably one of the most famous dinosaurs; in reality, it was much smaller than what people see on-screen, popularized by the Jurassic Park franchise. The real Velociraptor, which lived about 75 to 71 million years ago during the late Cretaceous period, was only about 3 feet tall and 6 feet long, weighing roughly 30–40 pounds. Its name means “swift thief,” appropriately named because it was a fast and intelligent predator.
Velociraptor was a bird-like dinosaur because its feathers preserved in some of the fossils, discovered in Mongolia and Northern China. Paleontologists have also thought that Velociraptor was a very agile runner, since it can run to as many as 40 miles per hour, and with that speed could have used its sharp, sickle-shaped claws while catching its prey.
Fun Fact: Velociraptor fossils found in Mongolia’s Gobi Desert are often found locked in combat with its prey.
4. Stegosaurus
Another favorite of many is the Stegosaurus, primarily because it has a peculiar double row of huge, plate-like structures along its back and spikes in its tail. Its name meaning “roof lizard,” Stegosaurus lived in North America during the late Jurassic period, roughly about 155 to 150 million years ago. Although this was a large dinosaur, reaching up to 30 feet long and weighing just less than 5 tons, the Stegosaurus had one of the smallest brains in proportionate size, hence the misconception that this creature was unintelligent.
The plates on its back are still the center of debates among paleontologists due to the various ideas concerning their purpose. Some believe these plated structures served thermoregulatory purposes, but others consider that these were primarily display devices, probably used for attracting mates or deterring their potential predators, like Allosaurus.
Fun Fact: Despite its size and impressive appearance, Stegosaurus had a brain the size of a walnut.
5. Spinosaurus
Spinosaurus-a name meaning “spine lizard”-is one of the more mysterious and larger predatory dinosaurs; its popularity has been facilitated by its bizarre appearance and size. It was even bigger than T. rex: 59 feet in length and weighing up to 10 tons. It lived during the Cretaceous period generally in what is now North Africa, from about 112-93 million years ago.
Its most salient feature was its peculiar, sail-like structure running down its back, formed by an extended series of neural spines. What this apparent sail is truly for remains a mystery, although most theories range from display to thermoregulation. Unlike most other carnivorous dinosaurs, Spinosaurus was thought to be semi-aquatic: it spent much of its time catching fish in rivers and lakes.
Fun Fact: Spinosaurus was one of those few known dinosaurs that were swimmers; their anatomy was adapted for a semi-aquatic lifestyle.
6. Archaeopteryx
Sometimes referred to as the “first bird,” Archaeopteryx is a transitional fossil that provides the evolutionary link between dinosaurs and modern birds. This late Jurassic creature from about 150 million years ago had the bird-like features of feathers and wings, but also had many dinosaur-like features, including sharp teeth and clawed fingers.
Fossils of Archaeopteryx are extremely well-preserved and form an important link in the explanation of the history of flight. While Archaeopteryx had feathers, there is an ongoing debate as to whether it was capable of actual flight like living birds. It may have been more of a glider, using its wings to hop between trees or to run away from a predator.
Fun fact: Probably the most famous fossils in the world, several good examples of Archaeopteryx come from the Solnhofen limestone quarries in Germany.
7. Brachiosaurus
Brachiosaurus is one of the iconic long-necked, towering sauropods. Brachiosaurus lived during the Late Jurassic period around 154 to 150 million years ago and reached lengths of as much as 82 feet – much of it neck. Unlike other sauropods, Brachiosaurus had longer front legs than back legs, so that its stance somewhat resembled that of modern giraffes, allowing it to browse high above other herbivores.
This huge herbivore could weigh up to 62 tons, making it one of the heaviest land animals that have ever walked the face of the Earth. Brachiosaurus remains have been unearthed in Colorado, Utah, and Wyoming in the US; Algeria; and Tanzania.
Fun fact: Brachiosaurus gained widespread fame due to its unforgettable feature in Jurassic Park, whereby the dinosaur sneezes on one of the actors.
8. Allosaurus
A huge, late Jurassic period predator, this creature was as deadly as it was small compared to the T. rex. Meaning “different lizard,” Allosaurus lived from about 155-145 million years ago and was one of the largest and supreme predators of its era. Reaching up to 39 feet in length, weighing about 2 tons, it was fitted with razor-sharp, serrated teeth meant to tear into flesh.
The fossils of Allosaurus were found both on the North American and European continents; it is especially famous for the state of Utah, home to Cleveland-Lloyd Dinosaur Quarry, boasting one of the largest assemblages of Allosaurus fossils anywhere in the world. Some paleontologists believe that Allosaurus hunted in packs, attacking great herbivores like Stegosaurus and Apatosaurus.
Fun Fact: Allosaurus is the official state fossil of Utah, and more than 60 Allosaurus specimens have been discovered within Cleveland-Lloyd Dinosaur Quarry alone.
9. Apatosaurus
A close cousin of Brontosaurus, Apatosaurus is among the largest sauropod to have existed during the late Jurassic age, about 152 to 151 million years ago. It reached lengths of up to 75 feet and weighed more than 22 tons. The name Apatosaurus means “deceptive lizard,” a huge herbivore which, in all probabilities, used its long neck for high vegetation reachable in forests and grass plains.
For many years, there was confusion between Apatosaurus and Brontosaurus because paleontologists thought they belonged to one genus. In fact, recent studies have confirmed that they are separate; Brontosaurus stands out because it is much smaller and has somewhat unique skeletal anatomy.
Fun Fact: Apatosaurus could whip its long tail into incredible speeds in defense of itself against the predators, such as Allosaurus.
10. Pteranodon
Although technically not a dinosaur, Pteranodon is one of the best-known pterosaurs-flying reptiles-that lived during the late Cretaceous period (100 to 66 million years ago). With a wingspan up to 33 feet, Pteranodon was among the largest flying creatures of its time. The most striking feature of Pteranodon is the large crest adorning its head, which might have been used for balance while flying or for display.
Pteranodon lived in what is now North America, especially along coastlines, hunting fish with its very long, toothless beak.
Fun Fact: Fossils of the Pteranodon have been found in Kansas. During the Cretaceous period, Kansas was part of a shallow sea.
Conclusion
Dinosaurs will always amaze us as we find out more about their amazing history from the study of fossils and research. Each of these species will hold a special place in the annals of life on Earth, providing us with insight into a world that took place millions of years ago. Be it the mighty T. rex, the gentle Triceratops, or the enigmatic Velociraptor, these prehistoric giants inspire curiosity and awe across generations.
