Australian Dinosaur Story
Student Activity 5
~ Society and the environment
Two Ichthysaurs - These big reptiles are about 5 metres long. They live in the sea, and will need a lot of swimming room. For food, they eat a lot of fish and squid.
||Three Muttaburrasaurus - These are very large Ornithopod dinosaurs, being about 7 metres tall. They walk about on all four feet, and are herbivores, slashing down the large ferns and cycads that grow in the forest. Being such big animals, they need lots of food.|
||Two Austrosaurus - These are huge Sauropod dinosaurs, and are about 20 metres long. They are herbivores, and being cold blooded, need relatively less food for such large animals. They move about quite slowly on all 4 legs, and their long necks allow them to reach leaves on very high branches.|
||One Theropod - This is a big fierce hunter. It is a fast moving carnivore, and being about 8 metres long, needs a lot space. It hunts other reptiles for food, and cannot share an enclosure with any animals that it might attack.|
||Ten Coelurosaurs - They are small, nimble carnivores up to half a metre in height. Their diet might consist of insects, frogs and very small reptiles.|
||Six Ornithopods - These dinosaurs run and walk about on their hind legs as many present day birds do. They vary in height, growing to between the size of a chicken and an emu. They are herbivores, eating low-growing vegetation.|
||Four Pterosaurs - These are flying reptiles. They are large, with very light bodies so they can fly. Their wing span is about 5 metres. They have membranes of skin to form these wings, much like present day bats. They are very good at flying and gliding, so they are going to need a very large enclosure. They are carnivores, mainly feeding on fish and small reptiles.|
||Twenty five Ammonites - These are marine animals. They live in the sea, where they swim around and feed off small fish and other small marine animals. They are up to 1 metre in size.|
Your zoo will also include the plants found in the Cretaceous Period.
These include giant ferns, cycads, and ginkgos.
