The Lake Macquarie Petrified Forest is a petrified pine tree forest at Fennell Bay, Lake Macquarie, New South Wales, Australia. Geologically it is located in the Permo-Carboniferous strata. [1] The nearest town is Swansea. [2]
The petrified forest was first referred to in print (as Kurrur Kurran) within a grammar of the local Aboriginal people published in Sydney in 1834 by missionary minister Lancelot Threlkeld. [3] [4] The scientific aspects of the site were first addressed in detail by the geologist priest William Clarke, who visited the area in 1842 and prepared a detailed report which was subsequently presented to the Geological Society of London and published in its proceedings for 1843. [3]
The fossil forest (Kurrur Kurran) was in 2009 nominated to the State Government as being State significant heritage, but has not been listed as such yet.[ citation needed ] In the meantime the best available scientific collection of silicified wood from the fossil forest (itself listed as local heritage) passed to the care of the City of Lake Macquarie which after keeping it for some time disposed of it (into the Lake) without notifying any of the geologists interested in or studying the fossil tree horizon.[ citation needed ]
The fossil tree horizon extends at least as far as the coast, where it can be found a little to the south of Catherine Hill Bay.[ citation needed ] Work continues trying to trace if this might be a very extensive horizon traceable right across the preserved Sydney Basin (e.g. to Marrangaroo in the west).[ citation needed ]
It has been generally accepted[ by whom? ] that the trees were both killed and buried (preserved) by ash from a volcanic eruption, [2] likely occurring somewhere well off the present eastern coastline.[ citation needed ]
The Wiradjuri people are a group of Aboriginal Australian people from central New South Wales, united by common descent through kinship and shared traditions. They survived as skilled hunter-fisher-gatherers, in family groups or clans, and many still use knowledge of hunting and gathering techniques as part of their customary life.
Petrified wood, also known as petrified tree, is the name given to a special type of fossilized wood, the fossilized remains of terrestrial vegetation. Petrifaction is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement. The organic materials making up cell walls have been replicated with minerals. In some instances, the original structure of the stem tissue may be partially retained. Unlike other plant fossils, which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material.
The Florissant Formation is a sedimentary geologic formation outcropping around Florissant, Teller County, Colorado. The formation is noted for the abundant and exceptionally preserved insect and plant fossils that are found in the mudstones and shales. Based on argon radiometric dating, the formation is Eocene in age and has been interpreted as a lake environment. The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing a diatom bloom. As the diatoms fell to the bottom of the lake, any plants or animals that had recently died were preserved by the diatom falls. Fine layers of clays and muds interspersed with layers of ash form "paper shales" holding beautifully-preserved fossils. The Florissant Fossil Beds National Monument is a national monument established to preserve and study the geology and history of the area.
A polystrate fossil is a fossil of a single organism that extends through more than one geological stratum. The word polystrate is not a standard geological term. This term is typically found in creationist publications.
Glossopteris is the largest and best-known genus of the extinct Permian order of seed plants known as Glossopteridales. The genus Glossopteris refers only to leaves, within a framework of form genera used in paleobotany. Species of Glossopteris were the dominant trees of the middle to high-latitude lowland vegetation across the supercontinent Gondwana during the Permian Period. Glossopteris fossils were critical in recognizing former connections between the various fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica.

Awabakallanguage is an Australian Aboriginal language that was spoken around Lake Macquarie and Newcastle in New South Wales. The name is derived from Awaba, which was the native name of the lake. It was spoken by Awabakal and Wonnarua peoples.
The Awabakal people, are those Aboriginal Australians who identify with or are descended from the Awabakal tribe and its clans, Indigenous to the coastal area of what is now known as the Hunter Region of New South Wales. Their traditional territory spread from Wollombi in the west, to the Lower Hunter River near Newcastle and Lake Macquarie in the north.

Kuringgai is an ethnonym referring to an Indigenous Australian people occupying the territory between the southern borders of the Gamilaraay and the area around Sydney, and an historical people with its own distinctive language, located in part of that territory.
Lancelot Edward Threlkeld was an English missionary, primarily based in Australia. He was married twice and survived by sons and daughters from both marriages. Threlkeld is known for his work with Biraban in recording and publishing English translations of the Awabakal language.
Lake Macquarie is Australia's largest coastal lagoon. Located in the City of Lake Macquarie and Central Coast Council local government areas in the Hunter and Central Coast regions of New South Wales, Australia, it covers an area of 110 square kilometres (42.5 sq mi) and is connected to the Tasman Sea by a short channel. Most of the residents of the City of Lake Macquarie live near the shores of the lagoon.
Biraban was a leader of the Awabakal people, an Aboriginal Australian people who lived in the area around what is today Lake Macquarie. His native name prior to Awabakal initiation was We-pohng; his naming as Biraban is reference to his totemic relationship with the eaglehawk.

Reverend Dr John Fraser was an Australian ethnologist, linguist, school headmaster and author of many scholarly works. He is known for his revised and expanded version of Lancelot Threlkeld's 1834 work, An Australian Grammar, with the new title An Australian language as spoken by the Awabakal, the people of Awaba or Lake Macquarie being an account of their language, traditions and customs / by L.E. Threlkeld; re-arranged, condensed and edited with an appendix by John Fraser (1892). In this, Fraser created new divisions and terminology for some Aboriginal groups in New South Wales.
Reids Mistake Formation is a geologic formation in the Sydney Basin in eastern Australia. It may be seen at the Swansea Headland Petrified Forest, near Swansea, New South Wales. Formed in the late Permian, it is part of the Boolaroo Subgroup of the Newcastle Coal Measures.
A large petrified forest thought to date to the Paleocene at around 55 million years old is located on and around the grounds of Cherokee Ranch in Douglas County, Colorado. These Denver Basin fossils include plants similar to the modern laurel tree family. At least 40 large petrified logs have been discovered on the Cherokee Ranch property; the castle on the ranch site includes more than 4,000 pieces of petrified wood in its construction.
