hey,i want to ask something,but maybe it's just a silly question..i want to ask you guys,especially if there are some prehistoric thing nerd in here.do giant bichir called "Bawutius" exist,which i see from the picture are more than 2 m long?and giant lungfish:Neoceratodus tuberculatus and coelacanth:Mawsonia that grow up to nearly 6 meter long?i am also a prehistoric thingy nerd,but i kinda doubt if there is a monster like that...thanks
