15 Dinosaurs from The Cretaceous You Absolutely Must Know!

Welcome back, dinosaur enthusiasts! We’re going on a journey back to the Cretaceous period, the last period of the Mesozoic Era, when dinosaurs reigned supreme on Earth. Join us as we explore 15 incredible dinosaurs that roamed the ancient landscapes. Let’s begin with the most famous of all dinosaurs!

Tyrannosaurus Rex

The mighty Tyrannosaurus rex, or T. rex, was a fearsome carnivorous dinosaur. It is one of the largest known land predators, with sharp teeth, powerful jaws, and tiny arms, and the only thing that could stop the T-Rex was an asteroid that hit the Earth.


Triceratops was a herbivorous dinosaur known for its iconic three-horned face. It had a large bony frill and a sturdy body, making it a formidable opponent to predators. It disappeared together with the T-Rex 65.5 million years ago.


Velociraptor was a small, agile dinosaur with sharp claws and a keen intelligence. Contrary to popular belief, it was much smaller than its portrayal in movies.

The Cretaceous period was in general a great time for dromaeosaurid dinosaurs. Utahraptor lived during the early Cretaceous 135–130 million years ago. Microraptor 120 million years ago, Deinonychus 115 million years ago, Buitreraptor 98 million years ago, and the Velociraptor 75–71 million years ago.


Ankylosaurus was a heavily armored herbivorous dinosaur. It possessed a thick, bony plate covering its back and a club-like tail that it used for defense against predators.


Parasaurolophus was a herbivorous dinosaur with a distinct, elongated crest on its head. This crest likely produced sound, possibly for communication or mating purposes.


Spinosaurus was a massive carnivorous dinosaur with a sail-like structure on its back. It is known for its elongated snout and powerful jaws, suggesting it was a skilled fish hunter.


Argentinosaurus was a gigantic herbivorous dinosaur with a long neck and forelimbs that were longer than its hind limbs. It is believed to have been one of the tallest dinosaurs.


Gallimimus was a fast and agile dinosaur that likely moved in herds. It had a slender body, long legs, and a beak-like snout, indicating a diet of plants and small animals.


Pteranodon was a flying reptile, not a dinosaur, belonging to the group known as pterosaurs. It had a large wingspan and a crest on its head, enabling it to soar through the skies.


Edmontosaurus was a large herbivorous dinosaur resembling a duck-billed platypus. It had a broad, flat snout and hundreds of tightly packed teeth, which it used to grind plant material.


Iguanodon was a herbivorous dinosaur that possessed a unique thumb spike, which is believed to have been used for defense or foraging. It was one of the first dinosaurs to be discovered.


Quetzalcoatlus was a massive pterosaur and one of the largest flying creatures ever known. With a wingspan reaching up to 33 feet (10 meters), it soared through the skies, likely scavenging for food.


Sinosauropteryx is a small feathered dinosaur that lived during the Early Cretaceous period, approximately 125 million years ago. It is an important fossil discovery because it was one of the first non-avian dinosaurs found with preserved feathers.


Protoceratops is a herbivorous dinosaur that lived 75 to 71 million years ago. It was a medium-sized dinosaur, measuring around 2 meters or 6 feet in length, with a robust body with a beaked snout, a relatively large head, and a frill at the back of its skull.

We’ve encountered a magnificent array of dinosaurs that once roamed the Cretaceous landscapes. Countless remarkable dinosaurs have roamed the Earth throughout history, and we may not have been able to include every dinosaur, but the ones we did explore provided a captivating glimpse into the diverse and fascinating world of the Cretaceous period.
