An international team of researcher has expose the earthly concern ’s big fossilised skeleton of a heavyweight , a find that suggests this group of animals became huge much in the first place than antecedently thought . The squad estimates that the whale was up to 26 meters ( 85 feet ) in length and librate between 130 and 150 tonnes . That stimulate it the largest extinct animal ever observe , even bigger than the large known dinosaur .
The whale has been dub Giuliana , after Lake San Giuliano in southern Italy where it was found . The squad accumulate the clappers between 2006 and 2008 and had to wait for the level of the lake to be low-pitched enough for them to hollow the sphere . They discovered part of the skull which permit them to establish the animal ’s size of it . They also encounter vertebrae and a 3 - meter - long ( 9 - foot ) costa ivory that ’s like in size to New blasphemous hulk ribs . The determination are reported in the Royal Society ’s journalBiology Letters .
The skeleton is 1.5 million year honest-to-god and is likely to be a blue whale , given the law of similarity between the fossil and living specimen . The lead researcher , Giovanni Bianucci from the University of Pisa , tell Italian newspaperLa Repubblicathat the squad would get it on to follow up their study and conduct more test to reassert their finding and maybe even line up more peculiar characteristics of this ancient animal .
The discovery of the fogy also casts uncertainty on exactly when heavy baleen whale arose . The squad suggests that Brobdingnagian whales might have evolved at least 3.6 million years ago if not further back in fourth dimension , around 6 million years ago , millions of years earlier than previously guess .
“ The fact that such a large heavyweight existed that long ago suggests that turgid giant had been around for quite a while , ” co - generator Felix Marx , a palaeontologist at the Royal Belgian Institute of Natural Sciences in Brussels , toldNational Geographic . “ I do n’t imagine metal money can evolve to such a size of it overnight . ”
However , the researchers stress in their paper that these vast whales were the elision rather than the average , and smaller whale species were a slew more vulgar until 3 million eld ago . The blue whale is the enceinte animal that ever existed . The species is currently separate asendangeredwith between 10,000 and 25,000 soul left in the wild .
