Dinosaurs and fossils
The Eromanga sea
100 million years ago, there was a
inland sea called the Eromanga
sea and it had many predators and
animals. It was a dangerous place
to be.
Now you can dig them up in
Richmond and Hughenden. My
family and I found a lot of fossils.

What was in the Eromanga sea?
The only thing left
of them is their
inner vertebrae
which is fossilised.
There were lots of
little things in the
Eromanga sea.
In the Eromanga sea
one of these was
called Belemnites.
They were about 1
to 10 cm long.
This is my belemnite and ammonite
Another animal
was the
ammonite. It got
to as big as a
tractor tyre and to
as little as a 5 cent
piece.
After the inland sea
After the sea retreated in the late Cretaceous period, the world
moved dramatically. If you lived in Australia you could walk to
South America and then China. After that, large conifer forests
popped up all around the world. Then the dinosaurs evolved.
The Cretaceous period
The dinosaurs ruled the forests.
Most of the sauropod bones you
find are the legs and surrounding
parts of the animal as lots of
sauropods got stuck in the mud
and were eaten by other dinosaurs.
In Winton there is
evidence of a
dinosaur stampede,
the only recorded
dinosaur stampede
in the world.

Fun fact - The
cretaceous
period lasted
from 100
million years
ago to 65
million years
ago.

Where dinosaurs live and eat
 The dinosaurs also lived in the
sea. They got really big, up to
30m in length. They also had
big teeth and tails.
Some moved really fast,
up to 70 kph. Most of
them ate fish or other
dinosaurs.

Where dinosaurs live
The land that the dinosaurs lived in were the conifer forests.

Because there was lots of food and water, the meat
eating dinosaurs had lots of food which were the
plant eating dinosaurs.
Dinosaurs dying
The dinosaurs died out after a meteor hit the coast of Mexico.
Upon the impact of the meteor, rocks were flung up into space.
When the rocks re-entered Earth’s atmosphere, the friction was so
high they were on fire. A giant fire occurred and killed most of the
dinosaurs. An ice age happened and killed the last few dinosaurs.
Bone extraction
Dinosaur bones are very fragile
because they’re not completely
turned to stone. The dinosaur
bone takes a long time to get
out of the rock. There are many
tools used to get the bone out
of the rock. Some tools have big
vibrations and some take just
two grains of rock off at a time.

Bone extraction
At Winton, one three week dig can produce ten years of
work for eight people. Winton has the most productive
dinosaur bone extraction plant in the world.
