A new dinosaur species has been identified , and it ’s a birdlike creature ( pictured ) that ’s 15 million years older than the first raspberry . Haplocheirus sollers is another dinosaur whose proto - bird characteristics make it a possible predecessor to birds .
There ’s so little grounds from the dodo record during the time that birds evolve that scientist have debated whether birds evolve from dinosaur , or severally . Haplocheirus , possessing some characteristics of a flightless bird while still being undeniably a dinosaur , is an significant hint in lick this mystery .
A group of Chinese paleontologists published a newspaper about the new dinosaur yesterday in Science , and a spillage about their workplace explains :
A new fellow member of a peculiar grouping of dinosaurs , the long - legged , stubby - fortify alvarezsauroids , is 63 million age older than other known members of this group , have it an important former member of the lineage that include razz and their closest theropod relatives , research worker report . The alvarezsauroids are relatively little , bipedal dinosaurs , and until this new fossil discovery , all the known example lived during the Late Cretaceous Period . One of the most strange characteristic of these Cretaceous alvarezsauroids was the exclusive , massive claw on each helping hand that was plausibly used for poke . . . Haplocheirus is the big have it off alvarezsauroid , implying that a shape of miniaturisation occurred over time . Also , Haplocheirus ’ hands have three fingers , the midway one much longer than the other two . The author propose that over prison term , these fingers fused into the giant claw that became a trademark of the Cretaceous alvarezsauroids .
In other cool dinosaur news , also publish in Science , a group of paleontologists studied the pigments from 125 - million - yr old dinosaur feather from the Sinosauropteryx and others . turn out these feathery creature own melanosomes containing eumelanin , which creates a grey and black colour in feathers , as well as pheomelanin , which creates reddish - chocolate-brown hues . Here is an artist ’s excogitation , from Science , of the coloration of the Sinosauropteryx . I think they might be . . . dancing ?
