Australia is the only country where opalised animal fossils are found. Opalised fossils are rare and precious; even more so because in Australia, it is rare to find fossils of any kind from the time of the dinosaurs.
Can fossils become Opalized?
Opalised fossils form in ways similar to other fossils, except that here they are preserved in silica. When the silica solution fills an empty cavity left by a shell or bone that has rotted away – like jelly poured in a mould – it may harden to form an opalised cast of the original object.
What dinosaurs lived in Missouri?

Are fossils rare?
Fossils are rare because their formation and discovery depend on chains of ecological and geological events that occur over deep time. As such, finding fossils involves not only perseverance and luck, but the discovery of any particular fossil also depends on the chance that the specimen preserved in the first place.
Does petrified wood turn into rock?

One of the greatest concentrations of petrified wood in the world is found in the Petrified Forest National Park in northeast Arizona. Logs as long as 200 feet long and 10 feet in diameter have been found in the park.

What kind of fossils are found in opal fields?
Some opal fields, such as White Cliffs and Coober Pedy, mainly produce fossils of marine (saltwater) plants and animals. At Lightning Ridge, most opalised fossils are from land-living or freshwater animals and plants.
What kind of fossils are found in Missouri?
Mammal fossils are generally uncommon in Missouri. Nevertheless, the state has been a source of spectacular finds. During the early 1800s, white settlers uncovered large fossil bones in the Big Bone River.
Which is the largest opalized fossil in the world?
Opalized fossils from the collection of the Australian Opal Centre, in the hand of Lightning Ridge opal miner Butch McFadden. The largest piece is a tail bone from the dinosaur Fostoria dhimbangunmal . (Jenni Brammall / Australian Opal Center)
Are there fossils in lighting ridge that are opalized?
Unfortunately, many miners would cut a rare fossil as the opal content was worth instant money. This practice has nearly stopped as most miners are now aware how rare they are. There have been all types of opalized fossils from Lighting Ridge, the most exceptional being the animal skulls.
