Pfupisa nyaya yacho:  Zvichida ndeimwe yemadhinosaur akakurumbira zvikuru akawanikwa nemhaka yomutsetse wakasiyana wemahwendefa akapakata pamusana payo. Zvino nzvero itsva yakaratidza kuti stegosaurus yechirume neyechikadzi yakanga ine mahwendefa ane chimiro chakasiana aifamba pamusana payo. Kunomutsa mukana wokuti madinosaur akashandisa mabhonzo ayo makuru, ayo aigona kusvika mamita 2,5, kukwezva mukwanyina. Masayendisiti akawana kuti stegosaurus yechirume (pamusoro) yakanga ine mahwendefa akapfekerwa zvombo ane chimiro chakasiana neyemadzimai (pasi) Nyanzvi dzezvakaitika kare dzinotaura kuti stegosaurus yechirume ingadai yakaashandisa kuratidzira simba rayo munzira yakafanana zvikuru neicho mapikoko anoita nhasi. Kutsvakurudza kwacho kwakabetserawo kupindura chinetso chakanga chavhiringidza nyanzvi dzezvinhu zvekare kwemakumi amakore. Vaviri ve"mbavha dzemazai" dzakakura seye turkey dzinonzi Romeo naJuliet dzakawanikwa dzichirara pedyo nepedyo padombo rine makore 75 miriyoni pakati pemakore a1990, asi zvakatora kusvikira zvino kuti nyanzvi dzigone kuziva bonde re'vadikani'. Zvino, vanzveri vanodavira kuti vakawana nzira yokusiyanisa nayo zvisaririra zvemadhinosaur maduku ane minhenga echirume neayo echikadzi. Vanoti misiyano inokosha pakati pevarume nevakadzi iri mumapfupa ari pedyo nomuzasi womuswe. Nyanzvi dzezvinhu zvipenyu zvekare paUniversity of Alberta dzakaongorora zvisaririra zviviri zvakawanikwa kuMongolia, izvo zvakatanga kurondedzerwa muna 2001. Imwe yacho ihomwe yakakwana, nepo imwe yacho isina pakati nepakati pemuswe wayo. Vatsvakurudzi vacho vakatarira uchapupu husiri hwomuzvarirwo hwokuti shiri dzaiva nemiviri miviri, uhwo huri pachena nhasi. Mienzaniso yacho inosanganisira mavhenekeri emapeacock, misoro mirefu yeshiri kana kuti minhenga mirefu yomuswe yeshiri dzomuparadhiso, dzinoshandiswa kukwezva uye kufadza vakaroorana. Dzinenge nguva dzose dzakakura zvikuru muvanhurume vanoita zvokudanana, kupfuura muvanhukadzi, vanoita chisarudzo. Chikwata chacho chakafungidzira kuti kufanana neshiri, madinosaur maduku ane minhenga akadai semaoviraptor aishandisa minhenga mirefu pamiswe yawo kukwezva madzimai, panzvimbo pokubhururuka. Vamwe vanhu veStegosaurus vakawanwa vane mahwendefa akapamhama nepo vamwe vakanga vane mahwendefa marefu ane muromo wakapinza uyo wakanga uri 45 muzana...
Zvinhu zvakawanikwa zvainzi Stegosaurus zvaiva nemhando mbiri dzematehwe pamusana pazvo - mahwendefa makuru akapamhama uye mahwendefa akareba akapinza aiva madiki. Nyanzvi dzakagara dzichifunga kuti dzaiva dzemarudzi akasiyana-siyana estegosaurus. Kutsvakurudza kutsva kwakawana kuti zvimiro zvakasiyana-siyana zvingasiyanisa varume nevakadzi. Nyanzvi dzezvakafa kare dzinoti mahwendefa acho anogona kunge akashandiswa kuti abatsire kukwezva mukadzi.
