Mu chipululu cha Gobi, chigoba cha dinosaur wachilendo, oviraptor, chidapezeka. Oviraptor ndi dinosaur yaying'ono ya theropod yaying'ono yokhala ndi mutu wofupikirako, wokongoletsa zapamwamba komanso mulomo wamiyendo. Chipululu chankhanza cha Gobi ku Mesozoic chinali dera la nyanja lopanda zipatso zamtunda, wokhala ndi mitsinje yodzaza. Mazira a mbewa ndi ufulu amaikidwa pamchenga wamchenga, ndipo mbalame za hobiperix zokhala pano. Pomwe pano oviraptors adabwera kudzasaka - ma dinosaurs otsogolera okha.
mafupa a oviraptor
Chigoba cha oviraptor chimadziwika ndi mabowo ambiri kapena zotulutsa mafupa okha. Chizindikiro cha oviraptor ndi chachifupi. Pali mabowo ambiri mu ma crest, ma mpweya pamlengalenga. Nyama iyi inali ndi fupa la m'mawere lotchedwa bere. Izi zimamuyandikira pafupi ndi mbalame zamakono.
Chikhulupiriro cha oviraptor chidakutidwa ndi chinthu chopanda kanthu ndipo chimawoneka ngati kutulutsa kwa mbalame yamakono - kassowary, kamene kamathandizira kuti adutsidwe azidutsa m'nkhwawa zowuma. Oviraptor ayenera kuti adabwera othandiza pazolinga zomwezo. Kapenanso kuti chizimbudzi chinali chizindikiro mkati mwa mitunduyo. Nthawi yakukhwima, banja la oviraptor lidapeza malo pafupi ndi posungira.
Yaikazi inkapanga chisa, ikumata mapanga ndi dothi mulu umodzi wa dothi ndi udzu. Kenako anapondaponda, ndikupanga kukhumudwa, kuyimirira pamwamba pa bowo.Mkaziyo anangotsitsa mazira pafupifupi khumi ndi atatu, ndikuwapatsa mzere umodzi pamwamba pa winawo. Mazira onse amaphimbidwa ndi nthiti kapena ma tubercles. Awiriwo amayenera kusamalira ana - kuteteza chisa kwa adani komanso kuwotcha, kuphimba kumanga ndi thupi. Ma dinosaurs atatuluka, oviraptors adayamba kuda nkhawa za kudyetsa anapiye awo. Makolo adapita kukasaka pachisamba, akubwerera ndi buluzi, dzira loyang'anira, mapira. Ndipo zina mpaka ana atatuluka mchisa ndikutsatira akulu.
