Frozen in Time offers a entire review of the fossil list of Antarctica framed inside of its altering environmental settings, supplying a window right into a earlier time and atmosphere at the continent. It reconstructs Antarctica’s evolving animal and plant groups as effectively because the fossil list allows.
The tale of ways fossils have been first stumbled on in Antarctica is a triumph of human pastime. It keeps this present day with glossy expeditions going out to distant websites each year to fill in additional of the lacking components of the continent’s nice jigsaw of lifestyles.

Collecting fossils in Antarctica One of the most common questions a palaeontologist is asked about collecting fossils in Antarctica is: Where do you find them? 7-kilometre-thick sheet. Mountain exposures are the best places to find Antarctic fossils, but these are often hard-to-reach places, which restricts the amount of equipment one can carry. Collecting fossils in normal weather conditions is often a routine job involving hammers, chisels, plaster for covering the larger specimens, and sometimes jackhammers or electric drills.
8 Another early report of fossils from Antarctica is one that has been largely overlooked. In February 1902, Frank Wilbert Stokes, a talented artist on the Belgian Antarctic expedition, collected a mere nine fossils at Admiralty Inlet, Louis Philippe Land. 10 Weller wrote: The first formal descriptions and illustration of fossils from Antarctica, collected during the voyage of the Jason in 1892 on Seymour Island. G Sharman and E Newton described these fossils in 1894, now known to be of Eocene age, in the Transactions of the Royal Society of Edinburgh.
Deeming it to be of only volcanic nature with rare plant life, Ross and his crew failed to recognise the highly fossiliferous nature of this small island. enraptured by the idea that Australia should be the first country to set up a whaling industry in the Antarctic region that he persuaded a retired whaling master, Svend Foyn, to finance an expedition down south in search of whales. They set sail in September 1894 from Melbourne with a small crew in the refurbished whaling ship Antarctic. Surveyor and amateur naturalist Carsten Borchgrevink was with them.
