I-Tyrannosaurus rex, eyaziwa nangokuthi i-T. rex noma "inkosi yesibankwa esingumashiqela," ibhekwa njengesinye sezidalwa ezinolaka embusweni wama-dinosaur. Eyingxenye yomndeni we-tyrannosauridae ngaphakathi kwe-theropod suborder, i-T. rex kwakuyi-dinosaur enkulu edla inyama eyayiphila phakathi Nenkathi Yasemuva Yokudala, cishe eminyakeni eyizigidi ezingu-68 edlule.
IgamaT. rexivela ngobukhulu bayo obukhulu kanye namakhono anamandla okuphamba. Ngokocwaningo lwesayensi, i-T. rex ingakhula ifike ku-12-13 wamamitha ubude, ime cishe ngamamitha angu-5.5 ubude, futhi ibe nesisindo esingaphezu kwamathani angu-7. Yayinemisipha eqinile yemihlathi namazinyo abukhali akwazi ukuluma ezimbanjeni futhi iklebhule inyama yezinye izibankwakazi, okuyenza ibe isilwane esizingelayo esesabekayo.
Ukwakheka komzimba ka-T. rex nakho kwayenza yaba isidalwa esishesha ngendlela emangalisayo. Abacwaningi balinganisela ukuthi ingagijima ngesivinini esingamakhilomitha angama-60 ngehora, ngokushesha izikhathi eziningana kunabasubathi abangabantu. Lokhu kwavumela u-T. rex ukuba ajahe inyamazane yakhe kalula futhi ayinqobe.
Nokho, naphezu kwamandla ayo amakhulu, ukuba khona kwe-T. rex kwaba okwesikhashana. Yaphila ngesikhathi seCretaceous Period sekwephuzile, futhi kanye namanye ama-dinosaurs amaningi, yashabalala cishe eminyakeni eyizigidi ezingama-66 edlule ngesikhathi somcimbi wokuqothulwa okukhulu. Nakuba imbangela yalesi senzakalo bekulokhu kucatshangelwa ngayo okuningi, ubufakazi besayensi bubonisa ukuthi kungenzeka ukuthi kungenxa yochungechunge lwezinhlekelele zemvelo ezinjengokukhuphuka kwezinga lolwandle, ukuguquka kwesimo sezulu, nokuqhuma okukhulu kwentaba-mlilo.
Ngaphandle kokuthi kubhekwe njengesinye sezidalwa ezesabekayo embusweni wama-dinosaur, i-T. rex iphinde idume ngezici zayo ezibonakalayo eziyingqayizivele nomlando wokuziphendukela kwemvelo. Ucwaningo lwesayensi luye lwabonisa ukuthi i-T. rex yayinesakhiwo se-cranial esinobunzima obuphawulekayo namandla, esivumela ukuthi inqobe inyamazane yayo ngokushaya ikhanda ngaphandle kokulimala. Ukwengeza, amazinyo ayo ayevumelana nezimo kakhulu, eyivumela ukuba ihlukanise kalula izinhlobo ezahlukene zenyama.
Ngakho-ke, i-T. rex yayingesinye sezidalwa ezinonya kakhulu embusweni wama-dinosaur, sinekhono elimangalisayo lokuphanga kanye nokusubatha. Naphezu kokushabalala ezigidini zeminyaka edlule, ukubaluleka kanye nomthelela wayo kwisayensi namasiko esimanje kusabalulekile, kuhlinzeka ukuqonda ngenqubo yokuziphendukela kwemvelo kanye nemvelo yemvelo yezinhlobo zokuphila zasendulo.
