Alamosaurus

Alamosaurus

  • Scientific Name:Alamosaurus
  • Most common Location:Cretaceous
  • Conservation Status:Extinct

More Facts

Alamosaurus was a massive, plant-eating dinosaur that lived during the Late Cretaceous period, around 70 million years ago. With its towering height, long neck, and giant body, it was one of the largest sauropods of its time, roaming the ancient landscapes of what is now North America.

As a herbivore, Alamosaurus fed on trees, ferns, and other vegetation, using its long neck to reach high into the treetops or low to the ground for plants. Its massive size likely made it a difficult target for predators, but it was also believed to travel in herds for extra protection. Its long tail may have been used for balance or even as a defensive weapon against smaller predators.

At Hoo Zoo, our Alamosaurus helps visitors discover the world of giant herbivores, the role of sauropods in shaping ancient ecosystems, and how these colossal creatures survived in a world of predators. Observing this towering giant up close gives visitors a glimpse into the prehistoric past and the incredible scale of life millions of years ago.

Ankylosaurus

Ankylosaurus

  • Scientific Name:Ankylosaurus
  • Most common Location:Cretaceous
  • Conservation Status:Extinct

More Facts

Ankylosaurus was a heavily armoured dinosaur that lived during the Late Cretaceous period, around 66 million years ago. With its thick, bony plates, club-like tail, and low, sturdy body, it was one of the best-defended dinosaurs in history, built to withstand the threats of the Cretaceous landscape.

An herbivore, Ankylosaurus used its powerful jaws to chew on low-lying plants, shrubs, and ferns. Its distinctive body armor, made up of bony plates and spikes, provided excellent protection against predators like Tyrannosaurus rex. The most notable feature of Ankylosaurus was its tail club—a weapon of defense that could deliver powerful blows to attackers.

At Hoo Zoo, our Ankylosaurus helps visitors explore the evolution of defensive adaptations, the role of armoured dinosaurs in prehistoric ecosystems, and how these creatures survived in a world of apex predators. Observing this armoured giant up close gives visitors a chance to appreciate its incredible natural defences and its place in the ancient food chain.

Atrociraptor

Atrociraptor

  • Scientific Name:Atrociraptor
  • Most common Location:Cretaceous
  • Conservation Status:Extinct

More Facts

The type (and only) specimen of Atrociraptorholotype RTMP 95.166.1, was discovered by Wayne Marshall in 1995, in layers of the Horseshoe Canyon Formation also containing an Albertosaurus bonebed, near Drumheller. This bonebed is located at the top of Unit 4 of the Horseshoe Canyon Formation, which dates to about 68.5 million years ago. The only known specimen consists of parts of the upper and lower jaws—both premaxillae, a right maxilla, both dentaries—teeth and numerous small fragments. The skull appears to have been unusually short and tall. The teeth are relatively straight, but they emerge from the tooth sockets at an angle to the jaw line, resulting in a strongly raked row of teeth. A number of isolated teeth (previously referred to Saurornitholestes) have also been recovered from the Horseshoe Canyon Formation; they can be recognized by their unusually large serrations.

Carnotaurus

  • Scientific Name:Carnotaurus
  • Most common Location:Cretaceous
  • Conservation Status:Extinct

More Facts

Carnotaurus is a genus of theropod dinosaur that lived in South America during the Late Cretaceous period, probably sometime between 71 and 69 million years ago. The only species is Carnotaurus sastrei. Known from a single well-preserved skeleton, it is one of the best-understood theropods from the Southern Hemisphere. The skeleton, found in 1984, was uncovered in the Chubut Province of Argentina from rocks of the La Colonia FormationCarnotaurus is a derived member of the Abelisauridae, a group of large theropods that occupied the large predatorial niche in the southern landmasses of Gondwana during the late Cretaceous. Within the Abelisauridae, the genus is often considered a member of the Brachyrostra, a clade of short-snouted forms restricted to South America. [CREDIT: WIKIPEDIA]

Protoceratops

Protoceratops

  • Scientific Name:Protoceratops
  • Most common Location:Cretaceous
  • Conservation Status:Extinct

More Facts

Protoceratops was a small, herbivorous dinosaur that lived during the Late Cretaceous period, around 75 million years ago. With its short frill, beaked face, and stocky body, it was an early relative of the more famous ceratopsids like Triceratops, known for its unique features and herbivorous diet.

Feeding on plants, Protoceratops was a calm and grazing dinosaur that likely used its beak to clip vegetation from shrubs and low trees. While it wasn’t a predator, its sturdy body and frilled head may have offered protection against potential threats. It was one of the first ceratopsians to evolve a frill, which might have been used in communication or mating displays.

At Hoo Zoo, our Protoceratops helps visitors discover the origins of horned dinosaurs, the evolution of herbivores, and how these early species adapted to their environments.
