When two brother were walking near a reservoir in a little town in northern Japan , one noticed something queer in the ground . The brothers collected a few of the challenging small-arm and took them to paleontologist at a nearby university .
The pieces turn out to be fogey of the oldest bird ever found in Japan : an ancient , toothed , diving bird whose species had never been identify by science .
Two brothers in Japan happened upon the fossilized remains of the country’s first and oldest fossil of a diving bird. The new species is namedChupkaornis keraorum.
The new mintage , namedChupkaornis keraorum , belonged to a group of ancient birds , hesperorinthiforms , that were flightless , expert urine divers during the Cretaceous.[Avian Ancestors : dinosaur That Learned to Fly ( Gallery ) ]
Chupkaornis , scientist estimate , live between 90 million and 84 million years ago , when dinosaurs vagabond the Earth . It is the " advantageously - preserved " specimen of this kind of raspberry from Asia , and the first hesperorinthiform found from the eastern part of the Eurasiatic continent , grant to astudy published Tuesday ( Aug. 8) in theJournal of Systematic Palaeontology .
" There has never been a bird likethis discover in Japan before . It ’s exciting any time you may put a new dot on themap , " Anthony Fiorillo , conservator and vice president of research and aggregation at the Perot Museum of Nature and Science in Dallas , narrate Live Science . " It ’s really helping us translate the global distribution of awidespread grouping of bird . And it helps us understand their early evolution . "
Fiorillo , who was a carbon monoxide - source of the study , told Live Science that the snort was the size of it of a " effective - sized duck " and gobble up Pisces , which it dive for and captured using its astute dentition . The boo ’s fossil boast brawny hind limbs and somewhat skimpy forelimbs , suggesting that the bird was made for the urine and expend minimum time on shoring laying eggs .
" Their hard suit was swim and diving , not walking , so if one was unfortunate enough to be too far from water when a theropod wandered by , it could very well have becomedinosaur food for thought , " Fiorillo said .
Scientists have know about hesperorinthiforms since the recent nineteenth century , when a Yale University fossilist came across the remains of one of the birdie in Kansas ( an inland sea cover middle America during the Cretaceous ) . Since then , several specimens of the ancient diving dame have been found in the Northern Hemisphere , particularly in North America , but rarely in Asia .
The uncovering ofChupkaornis , the oldest known Asian hesperornithiform , suggest that these birds dispersed to the easterly edgesof Asia no later than 90 million to 84 million long time ago , the researchers say .
" This report cater [ a ] better intellect in[to ] the early evolution of this group and the origin of diving event in birds , " lead author Tomonori Tanaka , said in astatement . Tanaka is a doctorial educatee in the Department ofNatural History Sciencesat Japan ’s Hokkaido University . [ Photos : Mummified Bird Wings preserve in Amber ]
The specimen , which was retrieve in 1996 , consists of nine fossilized corpse , including vertebrae and femur fragments . An early outline , published in 2000 in Japanese , discover the fossil but had not go steady it as precisely . Chupkaornis keraorumis named after its unique location and its discoverers . " Chupka " is the word used by endemic people from Hokkaido for " eastern,“and " keraorum " is named after Masatoshi and Yasuji Kera , who foundthe specimenduring their base on balls .
Fiorillo point out that big palaeontological discoveries are often made by everyday masses who take specimens to local universities or museums . He order that one of the most significant fossil in the Perot Museum was find by a " even " guy who liked to research an old riverbed near Lake Grapevine , in Texas . That fogey turned out to representFlexomornis howeiand is among the quondam known fossilized bird continue in North America .
" There ’s a lot of rock on this planet , and there really are n’t that many paleontologist . But there are a lot of curious the great unwashed around , " Fiorillo said . " And no matter what country you ’re in , the great unwashed are curious about where they live . "
Chupkaornis keraorumis presently held in a appeal of theMikasa City Museumin Hokkaido , Japan .
