Turning back the clock to the late 1800s, the first Australian dinosaurs were discovered but
remained extremely rare among Australian fossils. Between the time
1932 and 1981 no new dinosaur research was carried out, though in recent
years some exciting discoveries have been made.
Dinosaurs dominated Earth for more than 160 milion years. The stamps in the mini-sheet show a scene from the early Cretaceous period in Australia (more than 100 million years ago). Two of these stamps are issued as self adhesive too.
Flying reptiles or pterosaurs were not dinosaurs. However, they lived at the same time and were warm-bloodedthe energy demands of flight could never be met with a cold-blooded metabolism. Ornithocheirus lived in the Late Cretaceous and is also found in Europe, South America and Africa.
During the 19th century, in England many fragmentary pterosaur fossils were found in the Cambridge Greensand
First found in Australia in 1979, near Boulia in south-western Queensland. It was a coastal species, and had a wing span of about 2.5 metres.
About the size of a chicken with a skull only 6
centimetres long, Leaellynasaura was a bipedal herbivorous dinosaur.
Its eyes were exceptionally large, as was the part of the brain
dedicated to processing visual signals (the optic lobes). It would
appear to have been adapted for life in semi-darkness. During much of
the Cretaceous, when Leaellynasaura lived, Australia was far closer to
the South Pole than it is now, and would have been almost continuously
dark for two or three months of each year. It has been suggested that
this little dinosaur, too small to migrate,remained active throughout
the long winter.
Allosaurus was the big predator of the North American Late Jurassic, 135 million years ago, so it is a surprise to find it in Australia some 10 to 20 million years later. It grew to 12 metres long, and weighed up to two tonnes.
This ornithomimosaur (ostrich mimic dinosaur) is known from two thigh bones discovered in 1992. It probably looked something like a big emu, but with strong arms and a long, stiff tail. It probably fed on both plants and small animals, and relied on its great speed to escape predators.
All but the tail of this dinosaur has been found, near
Muttaburra in Queensland. Many of its bones were originally collected
by local people, but after palaeontologists had excavated the remainder
of the skeleton, a public appeal was made for the return of bones and
the skeleton was reconstructed.
The broad head ended in a horny beak which was used to
tear leaves, twigs and fruit from trees; further back in the jaws were
shearing teeth to slice up the food. The top of the snout was expanded
into a strange, hollow dome, similar to those seen in some duck-billed
