And it is not only landscapes. Isolated cave shafts punctuating the Nullarbor Plain preserve mummified remains of Tasmanian tigers and complete skeletons of long-extinct wonders such as Thylacoleo, the marsupial lion,&#8221; Dr. Barham said.<\/p>\n<p>&#8220;At the surface, due to the relatively stable conditions, the Nullarbor Plain has preserved large quantities of meteorites, allowing us to peer back through time to the origins of our solar system.<\/p>\n<p>&#8220;These features, in conjunction with the millions of years old landscape feature we have now identified, effectively make the Nullarbor Plain a land that time forgot and allow a fascinating deeper understanding of Earth&#8217;s history.&#8221;<\/p>\n<p>Dr. Barham is affiliated with The Institute for Geoscience Research (TIGeR), Curtin&#8217;s flagship Earth Sciences research institute.<\/p>\n<p>Titled &#8220;Enigmatic annular landform on a Miocene planar karst surface, Nullarbor Plain, Australia&#8221; and to be published in <i>Earth Surface Processes And Landforms<\/i>, the research was led by Dr. Matej Lipar from the Anton Melik Geographical Institute at the Research Center of the Slovenian Academy of Sciences and Arts.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            New technique unlocks ancient history of Earth from grains of sand\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Matej Lipar et al, Enigmatic annular landform on a Miocene planar karst surface, Nullarbor Plain, Australia, <i>Earth Surface Processes and Landforms<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1002\/esp.5459\">DOI: 10.1002\/esp.5459<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Curtin University<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.curtin.edu.au\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/phys.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Study unearths ancient reef structure high and dry on the Nullarbor Plain (2022, September  7)<br \/>\n                                                 retrieved  8 September 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-09-unearths-ancient-reef-high-nullarbor.html<\/p>\n<p>                                            This document is subject to copyright.
