Pfupisa nyaya yacho:  Dzakanga dzatova nomukurumbira unotyisa wokuva mhuka dzinoparadza zvikuru dzenguva yadzo, asi kunoratidzika kuti maTyrannosaurs akanga anewo kombamiro yokudyidzana. Imwe fundo itsva yakawana ufakazi hwokuti hama yaTyrannosaurus rex, inonzi Daspletosaurus, ingave yakanga yaita unzenza hwokudya vanhu. Nyanzvi dzezvinhu zvekare dzakawana zviratidzo zvokurumwa pahuro yakava zvisaririra yeDaspletosaurus muduku, uyo akararama makore anenge mamiriyoni 75 akapfuura. Uyu mufananidzo wemifananidzo unoratidza Daspletosaurus ichidya muviri womumwe muchiito chokuda kudya vanhu. Nepo kumwe kukuvadzwa kunoratidzika kuva kwakapfuurira mukati mokurwisana nedzimwe tyrannosaurs, kumwe kunoratidzika kuva kwakaitika pashure porufu. Masayendisiti anodavira kuti imwe Daspletosaurus, iyo yaigona kukura kuva mamita mapfumbamwe (30ft) sevanhu vakuru uye yairema matani mana, yakadyiswa mumuviri womwana muduku. Tyrannosaurus rex nehama dzayo vakanga vakangwara zvikuru kupfuura zvaifungidzirwa kare uye vaivhima vari mumapoka ayo aibatanidza nhengo duku nedzechikuru, vatsvakurudzi vakadaro. Masayendisiti anodavira kuti ane ufakazi hwokuti madhinosaur makuru anobata mhuka akanga ari mhuka dzeboka dzakangwara zvikuru, pasinei zvapo nokuti T-rex inoratidzirwa navose somunhu ane ngozi asi asina njere ari oga. Iyi ingano yakakura nemhaka yokuti kwamakore mazhinji mapfupa avo akacherwa aiwanzowanwa oga, vanzveri vanodaro. Pfungwa itsva yacho inobva pakuongorora mapfupa etyrannosaur Tarbosaurus bataar kubva kunzvimbo 90 dziri muRenje reGobi, Mongolia. Tarbosaurus, hama yaT-rex iyo yakararama makore anenge mamiriyoni 70 akapfuura, yakanga iri mhuka ine makumbo maviri yaikwanisa kureba mamita 12 uye yairema matani mashanu. Zvinoratidzika sokuti dzinenge hafu yedzinza remhuka dzacho dzaiva dzeboka rimwe chete, dzaisanganisira vakuru nevana vaduku, dzakafa pamwe chete. Zvakawanikwa izvi zvinobatsira kujekesa nyika ine utsinye yaigarwa nemadhinosaur. Dr David Hone, nyanzvi yezvinyorwa zvekare paQueen Mary University yeLondon, uyo akatungamirira kutsvakurudza akati: 'Chokwadi mhuka iyi yakanga iine upenyu hwakaoma, ichitambura kukuvadzwa kwakawanda mumusoro kusanganisira kumwe uko kunofanira kuva kwakanga kwakashata zvikuru. 'Zvinobvira zvikurusa...
Chiso chedehenya cheDaspletosaurus - hama yepedyo yeTyrannosaurus rex - yakawanikwa yakafukidzwa nezviratidzo zvekurumwa zvinoratidza kuti yakadyiwa payakanga yafa. Vaongorori vezvakaitika kare vanodavira kuti mumwewo Daspletosaurus akadyira pamuviri wacho. Godo racho rakawanikwa muDinosaur Provincial Park muAlberta, Canada, muna 1994. Yaivawo nezvironda zvaiita sokuti zvakakuvadzwa muhondo.
