Ingabe ama-dinosaur ayenemilomo?
Ucwaningo lwakamuva lusikisela ukuthi umbono ovamile wokuthi ama-dinosaur ayenamazinyo abonakalayo kungenzeka awulungile, futhi umbono wamanje uthi iTyrannosaurus rex yayinezindebe ngempela. Ucwaningo lwango-2023 olwenziwe uDkt Mark Witton wase-University of Portsmouth luthi ukubonakaliswa okudumile kwama-dinosaur kumafilimu afana ne-Jurassic Park akusasebenzi. Lolu cwaningo lwahlola izinyo elikhulu elalichithe izinsuku ezingaphezu kuka-500 emlonyeni we-Tyrannosaurus rex ngaphandle kobufakazi bokuthi laligugile, okuvumelana nakho konke okutholakele ngamazinyo atholakala emndenini wama-dinosaurs angama-theropod. Uma kuqhathaniswa nezingwenya nezingwenya, ezingenawo izindebe futhi ezinamazinyo alimala kalula, lo mbono uthi ubufakazi bubonisa ukuthi ama-theropod, kuhlanganise ne-Tyrannosaurus rex ayenezindebe ngempela. Kwakuyokulindeleka ukuba kube nokugqwala koqweqwe lwawo oluncane emazinyweni okufana kakhulu nezilwane zanamuhla ezinjengezingwenya ukube ama-dinosaur ayengenawo izindebe.
