Previous coinages are listed to distinguish separate countries within a common economy, but Wikipedia does not give enough detail to distinguish Tasmania from New South Wales. Transport of technology, customs, then language from one economy to another is suggested by the Google Earth paths, listed in historical order, such as:
Of special interest is the cells in the southern hemisphere, from telephony onwards, which have sites in the timeline for vehicle manuafacturing in South Australia. This is especially innovation in bush bashing which would contribute componets to a #LandDrone for monitoring Maralinga. Unusually, in comparison to mineral exploration, is this need does not decline. For example one of the isotopes caused by the original atomic bomb test is 242Pt (Platinum-242) which has a half-life ten times that of the estimated period of aboriginal occupation. That is the half-life, so there is still going to be 50% of the stuff lying around after that. Given that much time we can expect success, especially since South Australia already has this record of innovation. In those particular cells from the table above are links to historical records of various inventions and developments, leading to the manufacture of rovers in South Australia; but what is not categorised by the timeline is the development was for ruggedizing of vehicles or just an improvement to the manufacturing industry. From the example in LinkedIn some of the innovations still need to be ruggedized.
Can the broad specturm revolution hypothesis be extended to the extinction of the Gondwana megafauna? The original elucidation of the Neolithic culture in the Near-East could be better explained as the introduction of the mortuary house (10 000 years b.p. +2000,-2000), leaving the BSR hypothesis available as the economic basis for the Antediluvian culture but also that of the Clovis culture in the Americas. There is a summary on Wikipedia, but also there have been Sprigg Geobiology Centre seminars giving insight, including a history of fire abstracted here.
I am especially interested as Gavin Prideaux’s talk at the Mawson Lecture Theatre in 2018, raised the possibility that South Australia could be a focus for research of the broad spectrum revolution hypothesis. Putting the leading theory on human civilization back an order of magnitude, is not something you expect after a couple of red wines on a boring Thursday night in Adelaide. Turns out the whole University of Adelaide paleogeography group is working on lipids for age sequencing – what a delightful coincidence, with Dr McInerney listing “Palaeohydrology of the Holocene of Southeast Queensland” and in a geological timeframe it is no different to what it is now (except for the urban disruption of the Gold Coast).
Allison Karp has isolated the organic compounds for C4 grass fires and the C3 plant deposits previous to that, including from sediments taken by the International Global Core Program. Remains of the fire-controlled biomes contain long chain organic molecules separated by a cyclopentadienyl ring, whereas the older “petroleum” style molecules are with the benzene ring. We had a quick discussion, because all her time records have a notch where fire and C4 grasslands are not coincident, except the Chinese record which is coincident (and not Gondwana). She needs to take a drive up Mt Nebo near Brisbane, to see the conifer forest abutting the sclerophyll forest, and realise there are hotter fires again than what she has been modelling (I think it is a 1000 degrees hotter for a eucalypt crown fire just like a mine fire). Also she spoke about the role of free radicals in the C4 fire biomarker, but didn’t account for the sulphate-reducing bacteria in the conifer forest biome which may be oxidizing those benzene rings for the C3 equivalent (I am now thinking metallogensis of ferrocene to pyrite). Desperate to remember all the acronyms for the compound groups, my book order for “Organic Chemistry a Very Short Introduction” by Graham Patrick has arrived; so I am going to have to discipline myself.
Professor Prideax presented a rational synthesis of the facts behind the speculation on the Australian marsupial megafauna, such as that reported in Wikipedia:
Fire is crucial to maintaining modern subtropical grasslands, yet our understanding of the origins and evolution of this association on geologic timescales is limited, due in part to few co-eval records of both grass and fire proxies in the geologic record. The ambiguity of past ecosystem-fire dynamics impedes our ability to predict how these critical ecosystems may respond to the current changing climate. Polycyclic aromatic hydrocarbons (PAHs) are a complex suite of molecules that can derive both from the burning of terrestrial vegetation, as well as thermally mature fossil organic substrates. Distinguishing burn signatures with these compounds will make it possible to link paleo-fire and vegetation change in the past. I’ll present my recent progress developing a new biomarker approach that uses these compounds to constrain the relationship between fire and grassland ecology in both terrestrial and marine contexts during the Late Miocene C4 grassland expansion on the Indian Subcontinent. Results suggest that modern feedbacks between fire, seasonality and landscape opening were first initiated in the Late Miocene. I hope further use of this novel approach will address how regional differences in fire dynamics contributed to the globally asynchronous Mio-Pliocene grassland expansion, as well as other terrestrial ecosystem questions in Earth History.
Allison Karp is a molecular paleontologist and a current Ph.D. candidate in the Geosciences Department at Pennsylvannia State University in the United States. Allison received her B.A. in Biology and Environmental Earth Science from Washington University in St. Louis in the U.S, with additional field studies in paleoecology and ecology at the University of Queensland and the University of Hawaii. At Penn State, Allison is a NSF Graduate Research Fellow working with Dr. Kate Freeman studying isotope biogeochemistry. Her research focuses on improving isotopic and molecular tools to constrain abiotic-biotic feedback processes in deep time, in particular, fire-vegetation interactions.
The Emblems and Coat-of-Arms for nations shown in any region are in well-formed SVG (Scalable Vector Graphic) format. This is the 21st Century equivalent of engraving, in that each line is individually specified in the file, it isn't just a digital scan of a painting. There are many versions on the internet but the ones shown here have been programmed in a way that the image can be zoomed into for closer inspection. Engravings by Robert Hooke, Gould and others of the enlightenment, allowed publishing of drawings commissioned by scientists like Darwin and Banks, and which was the basis for modern peer review of natural science. In modern scientific work this technology has been replaced by high-defintion photographs and video programmes.
Rather than using simplified heraldic devices, these national emblems and Coat-of-Arms have modified these original biological and lithological drawings. To celebrate the work of the scientists and the modern programmers embracing that heritage, each is labelled with the authors user account and copyright notice from Wikipedia Commons, also a link to the web page as there may be a discussion of the design. To comprehend my excitement please see:
In the stratigraphic table above, regions that are adjacent have common cell boundaries, regions which are not contiguous don't. This came about as an attempt to maximise the space available for text. If for instance I had used hotpoints in a geographical projection there would be a few near-invisible points on a white page.
This is composed from the principle that history is periods of quiessance punctuated by change. Therefore artifacts in any archeological record are not recording changes but rather the quiet period before that change. Examples of this are the heritage building that has survived urban renewal. It is from the period before the activity. In this way the record of history is similar to a stratigraphic column. For in a stratigraphic column the periods of quiet deposition are shown as formations separated by the unconformities, that is periods of active erosion.
Where it is obvious, I have used technological events to puntuate the periods in the table. This is the archaeological concept that inventions revise culture, and I have also found this in my own experience with geological computing: successful technologies are quickly adopted because they are successful. I don't think anyone in history has enjoyed watching their children die. If there is something they can change in their society to prevent those deaths, the parents will do it.
The second principle of this table is also taken from the geologists stratigraphic column. The regional scope of the data set represented by the link is shown by boxes and member sub regions by boxes inside the outer box.
Where I have had the chance to research a geological formation I have used a dotted line around the website icons. This is implemented a style attribute of the enclosing HTML <nobr> element, which to enforces that they always appear at the same stratigraphic level, no matter what dimensions are used for the browser window.
Each table cell joining other table cells gives every boundary that occurs geographically. For example South Australia has only boundaries with Queensland, New South Wales, Victoria, Northern Territory and Western Australia. The arrangement of the table cell therefore describes the complete geographical arrangement of the sovereign entities.
In comparison the stratigraphic column boundaries are portayed as separated from the intervening strata (browse the style .precambrian in the ./gateway.css file) to imply the geological uncertainty, and a heavy dashed line is used for an eon which is only suggested.
Perhaps in the table above, to make the page more pleasing, I could have pasted a satellite image behind those hot-points, but I only wanted to show the information I had, and not have the reader focussing on a picture with no factual significance. The result is ugly, as it looks like an object model for a computer program, but it is quite compact. If you cast your mouse across the regions and boundaries you will see that they are captioned with titles.
The table also shows the Tau shaped time-space (+stratigraphic) continuum model. From at least the archaeologist's point of view, the longitude direction is aligned in the direction of time, with latitude at right angles. Longitude only affects the last day of time and so all history sits below the nexus of the two coordinates as in the diagram above. For an example, consider the scene in the film "Independence Day 4" where the aliens have flying saucers distributed around the globe hovering above the capital cities. Then in unison they begin attacking. Subsequently, for an archeologist investigating these ruins, he or she would have to adjust the time of day of the attack based on the longitude of the devastated city to demonstrate that the destruction occurred at the same instant. Otherwise, it would appear that it occurred during the previous day through the night to the next day. Then the title of the film would have to be changed perhaps to 'Independence Weekend 4' and I am sure Hollywood would never have made that film. Since setting up this table, there was the devastating tsunami in the the Indian Ocean, and this mathematical approach to the timing of geological events proved practical in firstly identifying where the epicentre occurred and then determining which islands and villages were affected so the rescue teams could visit them, as there wouldn't be the resources to visit every island at least in the time required to prevent further death.
To maintain the density of the text links, and keep the principle that every table data cell boundary represents a geographical relationship, the columns of links have been spaced or separated into groups by the unsorted list element "ul". Then by using the style attribute of "float" the columns of links occur as if they were separate "td" elements. The "ul" element is also conveninet for fading any background color (actually re-assigning the color with the style attibute) to make the text easier to read.
I started the table structure, because there was nothing else I could easily put on the Bigpond web site. I was re-assured that before Smith invented the geological map (of Britain), members of the Geological Society used tables to display lithology, I have found there are some extra benefits I didn't forsee:

Are you archiving pictures and other primary historical sources and worried about what date you should be using? Would you like to use the astronomical date calculator to give you a single integer for your index? On this page until about 2010 (ISO-8601), this was just a mockup on AD 1954 but I have scripted it to produce an estimate for a year from 9999 BC to 9999 AH. I thank Mr Ghazi Kraishan (and his wife) for answering my questions on the Islamic calendar.
