Chillagoe's geological and fossil record is unique. It is one of
the very few places in the world where fossil evidence can be found
from three different geological ages.
* The limestone bluffs, which dominate the town, contain remnants
of the early coral reef (500 million years ago) from a time when
Chillagoe was beach front property on the Australian landmass.
* The black soil plains of the Walsh River area are famous worldwide
for the distribution of magnificent specimens of ammonites, deposited
when the great inland sea inundated the continent during the cretaceous
period, at the same time that the
dinosaurs walked on other continents and their counterpart Australian
species left their bones in the Winton area, and their footprints
at Lark Quarry'.
* The third geological fossil period is from a relatively recent
era.It dates back to when the mega-fauna inhabited the grasslands.
The giant wombat Phascolonus gigas, the skull of which was 40 centimetres
long (about the size of a cow's head),
Palorchestes, the size of a horse, equipped with razor-like claws
up to 12 centimetres long, and a bizarre head crowned with a longish
trunk, the Chillagoe Kangaroo, which favowed a meat diet rather
than vegetarian, and Sarcophilus, the Tasmanian Devil, all roamed
the Chillagoe bushland.
The fossilised bones of these and other magnificent
creatures havc been found in fissures within the limestone and in
the debris of collapsed cave deposits. Standing at two metres high
and nearly three metres long, Dipraoadn optatum was the largest
marsupial that ever lived. This giant also browsed in the Chillagoe
landscape. Evidence for the existence of this grandiose creature
comes from the ashes of the cooking fires of an indigenous site,
the paintings of which have been dated as some of the oldest in
the world. |
| Several
years ago the fossilised skeleton of the most complete Elasmosaur
found in Australia was discovered in the ancient inland Apian Sea
area which bordered Chillagoe. 'Dave' as it has been nicknamed,
along with all the other special finds of the Chillagoe region,
now reside in museums, mostly in the basement, in southern
capitals or, as in the case of the specialised Chillagoe Kangaroo
and other miscellane are on display at Berkeley, California. Repeated
atternpts to obtain: replicas have been unsuccessful to date, except
for the return of a replica of the skull of a rare Ziphodont Crocodile,
which can now be seen at The Hub, The Chillagoe Information Centre.
Although there is an excellent Time-Line Display at
The Hub, there is nothing tangible to indicate that there is a fascinating
tale to be told on an epic scale - until now!
The life-sized reproduction of "Dave' will be placed at the
entrance to town and officially unveiled on Saturday, the 3d October
2009. Signage showing that Chillagoe is the apex to the 'Dinosaur
Triangle' together with other interpretive signage, will
give recognition to the unique geology of the region. Come and join
in and celebrate!
