Hylaeosaurus was a plant-eating Ankylosaur that lived in what is now southern England in the Early Cretaceous Period.

Discovered in the early 19th century, Hylaeosaurus stands as a pivotal figure in the history of paleontology. As one of the first three reptiles to be scientifically described—alongside Iguanodon and Megalosaurus—Hylaeosaurus played a crucial role in defining the very concept of dinosaurs.

Camarasaurus, known for its distinctive box-like skull and robust body, was a sauropod dinosaur that lived in North America during the Late Jurassic period. It is the most commonly-found sauropod in the Morrison Formation, a famous dinosaur fossil site in the western United States.

Carcharodontosaurus, one of the most formidable predators of the mid-Cretaceous period, roamed North Africa approximately 100 to 93 million years ago.

This massive theropod, whose name means “shark-toothed lizard,” was named for its large, serrated teeth, which were similar to those of today’s great white shark.

Measuring up to 13 meters (43 feet) in length and weighing as much as 15,000 kilograms (33,000 pounds), Carcharodontosaurus was a dominant force in its ecosystem.

Discovered in the Sahara Desert in the 1920s, this dinosaur has since captured the fascination of paleontologists and dinosaur enthusiasts alike, providing critical insights into the diverse and dynamic world of prehistoric predators.

Argentinosaurus, whose name means “Argentine lizard”, is one of the largest dinosaurs ever discovered. A member of a group of huge sauropods known as Titanosaurs, Argentinosaurus roamed South America during the Late Cretaceous period.

Herrerasaurus, one of the earliest known dinosaurs, is pivotal in our understanding of dinosaur evolution.

First discovered in Argentina’s Ischigualasto Formation, this Triassic predator roamed the Earth approximately 230 million years ago, a time when the landscape of the supercontinent Pangaea was dramatically different from today.

Plateosaurus was a large, bipedal herbivore, and an important member of the sauropodomorph lineage that eventually gave rise to the giant sauropods such as Apatosaurus and Brachiosaurus.

Eoraptor, one of the earliest known dinosaurs, gives us a fascinating glimpse into the dawn of dinosaur evolution. Discovered in the Ischigualasto Formation of Argentina, Eoraptor roamed the Earth approximately 231.4 million years ago, during the Late Triassic Period.

Amazingly, this small, agile dinosaur, measuring just 1 meter (3.3 feet) in length and weighing up to 10 kilograms (22 pounds), is thought to be an ancestor of huge sauropod dinosaurs such as Apatosaurus and Diplodocus.

Saturnalia is one of the earliest-known dinosaurs, and an important species in understanding the early evolution of sauropodomorphs – a group of dinosaurs that would eventually become some of the largest land animals the world has ever seen.

Although small, this Triassic period dinosaur had features linking more primitive dinosaurs to the later, more massive sauropods, such as Apatosaurus, Brachiosaurus, and other Mesozoic giants.

Liliensternus was a bipedal predator of the Late Triassic Period. This relatively lightweight, agile theropod would have been an effective hunter during its time.

Read on to discover more about this early ancestor of large predators such as Allosaurus and T. rex.
