I-Daspletosaurus - "Isilozi esesabekayo"
Isikhathi sokuba khona: Isikhathi sokukhathazeka - cishe eminyakeni eyizigidi ezingama-75 edlule
Isigcawu: Lizopharyngeal
Isizinda: Theropods
Izici ze-theropod ezejwayelekile:
- uhambe ngemilenze yasemuva enamandla
- wadla inyama
- Umlomo ohlome ngamazinyo amaningi abukhali, agoge ngaphakathi
Ubukhulu:
ubude 9 m
ukuphakama 3 m

Umsoco: UMayaso ezinye izibankwakazi
Kutholakele: 1970, USA, Canada
Njengama-tyrannosaurids amaningi, i-daspletosaurus yayihamba ngemilenze yayo yasemuva futhi inemihlathi emibi enamazinyo, ilungele ngokuphelele ukudwengula inyama yezisulu.
Uma kuqhathaniswa nokwakheka kwemihlathi, ibhungane kwadingeka lidle ukudla okunzima nokuqinile. IDaspletosaurus yayiyisisulu esikhulu futhi yayingabamba kancane futhi ikwazi ukunikeza ukumelana okufanele kuma-ceratops nama-ankylosaurs noma ama-hadrosaurs amakhulu.
Isici esivelelayo se-daspletosaurus ubude bezinto zangaphambili. I-Daspletosaurus, phakathi kwawo wonke ama-tyrannosaurids, yayinobude obukhulu kakhulu bezandulela zangaphambili ezihlobene nokulingana komzimba.
Izinsalela zama-daspletosaurs ezinama-hadrosaurs amancane esiswini zitholakele, okukhombisa ngokusobala kodwa ukuthi ama-dassletosaurs nawo ayewazingela la ma-dinosaurs.
Umthambo we-Daspletosaurus
Ekupheleni kweCretaceous, ama-dassletosaurs ayephila ngesikhathi ama-albertosaurs futhi gorgosaurs. Babelana nge-niche efanayo yemvelo. Futhi ngisho noma i-daspletosaurus itholakele, izazi zezimbali ekuqaleni zazithi yi-gorgosaurus noma i-albertosaurus, ngoba ziyafana ngobukhulu nangokwakheka. Lesi yisibonelo esingajwayelekile sokuhlangana kwezingane ezinkulu ezimbili zomndeni ofanayo.
Ezinye izifundiswa zikholelwa ukuthi ukuntuleka komncintiswano phakathi kwalezi zikhulu ezimbili kungenzeka ngenxa yezindawo, ama-gorgosaurs ayevame kakhulu ezindaweni ezisenyakatho, futhi ama-dassletosaurs ayevame ukubonakala eningizimu. Isithombe esifanayo sabonwa kwamanye amaqembu amadina. Ngakho-ke, singasho ukuthi ezinye izilwane ezidla ezinye zazo zazikhetha ukuzingela izinhlobo zazo ezithile futhi, ngenxa yalokho, zihlala ngokwezindawo ezaziyizisulu zazo.
Njengamanje, abahlaseli abanjena bahlukaniswe yimikhawulo ehlukene yemvelo, imbandezelo yokuziphatha neyokuma kwezwe ezinciphisa ukuncintisana.
