Riojasaurus was a sauropodomorph dinosaur from the Late Triassic Period. Discovered in the La Rioja Province of Argentina by paleontologist José Fernando Bonaparte in 1969, Riojasaurus stands out for its substantial size and robust build.

As one of the earlier members of the lineage that would give rise to the colossal sauropods of later periods, Riojasaurus provides invaluable insights into the adaptations and lifestyles of early herbivorous dinosaurs.

Barosaurus was a giant, plant-eating sauropod dinosaur that lived in North America in the Late Jurassic Period, approximately 155 to 150 million years ago.

This enormous dinosaur, whose name means "heavy lizard," was distinguished by its exceptional size, featuring a remarkably long neck and tail that made it one of the longest dinosaurs ever discovered.

Discovered in the rich fossil beds of North America's Morrison Formation, Barosaurus belonged to the same family – Diplodocidae – as the closely-related Diplodocus.

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.

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.
