MysteryFact:
Thrinaxodon was a small cynodont, or mammal-like reptile about the size of a cat


MysteryFact:

MysteryFact:
Torosaurus was discovered by John B. Hatcher and named in 1891


MysteryFact:
Fossils are widely distributed from the United States to China showing the success of this dinosaur group


MysteryFact:
Ankylosaurus was named by Barnum Brown in 1908


MysteryFact:
Recently palaeontologists have suggested that Anatotitan may just be a large Edmontosaurus


MysteryFact:
Though only the size of a badger, Didelphodon was still one of the largest mammals of the Mesozoic era


MysteryFact:
Allosaurus was the top predator of the Jurassic, terrorising the sauropods 100 million years before Tyrannosaurus


MysteryFact:
The nostrils of Brachiosaurus were located on top of the skull


MysteryFact:
Fossil finds hitherto ascribed to the 45 metre long and 30 tonne Seismosaurus are now believed to actually be a very old Diplodocus


MysteryFact:
It had wrists that allowed it to tuck its hands up close to its body in the same way a bird holds its wings


MysteryFact:
A peculiar wrist bone - the pteroid - supported a special membrane running across the neck which, when flying at low speeds, helps to prevent stalling


MysteryFact:
Plesiosaurs like Cryptoclidus were descendants of the land-living reptiles that had returned to the sea


MysteryFact:
Its teeth were arranged in a distinctive rosette at the end of its snout


MysteryFact:
Ophthalmosaurus had an almost completely toothless jaw


MysteryFact:
The single fossil remain is of an animal only five metres long, fairly small for a theropod


MysteryFact:
Ornithocheirus had the wing area of a small aeroplane, yet because of its hollow bones, its body probably weighed less than a human


MysteryFact:
Different species of Tapejara had different shaped head crests up to five times the size of the skull.


MysteryFact:
Utahraptor's toe joints were specially enlarged so that its massive claw could be raised upward and backward to avoid damage while running


MysteryFact:
Polacanthus is closely related to both the stegosaurs and ankylosaurs


MysteryFact:
Named after Leaellyn Rich, the daughter of the Palaeontologists Tom Rich and Patricia Vickers who found the skull


MysteryFact:
Muttaburrasaurus is a member of the iguanodontid group of dinosaurs


MysteryFact:
Its middle three fingers were bound together by a plump pad of skin, while its little finger could be curled over to grasp food. Its thumb had a vicious defensive spike.


MysteryFact:
Fossil evidence is controversial being based on a single ankle bone found near Melbourne, Australia


MysteryFact:
Koolasuchus was named after palaeontologist Lesley Kool


MysteryFact:
Anurognathus was so small that even dragonflies were probably too large for it to eat
