scientist have made a rather rare and wonderful breakthrough on a glacier in Antarctica : the first ever fossilized basis mallet on the southernmost continent .
Not only is it evidence of the first ground mallet ever discovered in Antarctica , it is a new species and the sole representative of a new genus . It has been namedAntarctotrechus balli , after George E Ball , an expert on reason beetle . However , it will be more commonly jazz as the slightly snappier Ball ’s Antarctic Tundra Beetle .
As you’re able to imagine , insects are rare in Antarctica . In fact , presently , its intact insect fauna live today consist of just three coinage of frankly rather boring flightless midges . And one of those is mistrust of being an intruder from an island in the Atlantic . Thisnew evidenceshows that there were in fact beetles crawling around the frozen country batch trillion of class ago .

Antarctica ’s want of biodiversity is not that surprising consider the deficiency of flora , wet , and warmth . Not many things can survive in such down in the mouth temperatures . But we know that billion of years ago , Antarctica was in reality warmer than it is today , with some botany that made it somewhat more habitable .
Dr Allan Ashworth from North Dakota State University and Dr Terry Erwin from the Smithsonian Institution discovered the fossilized forewings of two individuals on the 200 - kilometer - long ( 124 - mile - long ) Beardmore Glacier , which is a major outlet glacier of the East Antarctic Ice Sheet , near the Transantarctic Mountains . Their study is published in the journalZookeys .
The researchers think the beetle lived in the early to mid - Miocene , between 14 and 20 million years ago , with plant life dodo link withA. balliindicating it probably inhabited the sparsely vegetated banking concern of a stream that was part of an outwash plain formed from the run - off of methamphetamine hydrochloride thaw from the plenty .
The geological dating of these fossils also shows us that Antarctica believably remained a relatively soft and habitable place for millions of years after it part from Gondwana , the supercontinent it break away from that was made up of what is now Antarctica , South America , Africa , Australia , and the Arabian Peninsula .
This exciting uncovering beg the evenly exciting question , what else might we find out there under the ice ?
