Tyrannosaurus rex, izwi kandi nka T. rex cyangwa "umwami w'umugizi wa nabi," ifatwa nk'imwe mu nyamaswa zikomeye cyane mu bwami bwa dinosaur. T. rex, wo mu muryango wa tyrannosauridae uri mu muryango wa theropod, yari dinosaur nini y’inyamaswa zirya inyama yabayeho mu gihe cya Cretaceous, mu myaka igera kuri miliyoni 68 ishize.
IzinaT. rexIkomoka ku bunini bwayo bunini n'ubushobozi bwayo bukomeye bwo guhiga. Dukurikije ubushakashatsi bwa siyansi, T. rex yashoboraga gukura ikagera kuri metero 12-13 z'uburebure, ikagira uburebure bwa metero 5.5, kandi ipima toni zirenga 7. Yari ifite imikaya ikomeye y'urwasaya n'amenyo atyaye ashobora kuruma mu rubavu no gushwanyaguza inyama z'izindi dinosaur, bigatuma iba inyamaswa ikomeye cyane.
Imiterere ya T. rex yatumye iba ikiremwa cyihuse cyane. Abashakashatsi bavuga ko yashoboraga kwiruka ku muvuduko wa kilometero 60 ku isaha, inshuro nyinshi kurusha abakinnyi b'imikino ngororamubiri. Ibi byatumye T. rex yirukana umuhigo wayo mu buryo bworoshye no kuwutsinda.
Nubwo yari ifite imbaraga nyinshi, T. rex yamaze igihe gito. Yabayeho mu mpera za Cretaceous Period, hamwe n'izindi dinosaur nyinshi, yazimye mu myaka igera kuri miliyoni 66 ishize mu gihe cy'irimbuka ry'ibinyabuzima byinshi. Nubwo impamvu y'iki gikorwa yakunze kuvugwaho byinshi, ibimenyetso bya siyansi bigaragaza ko gishobora kuba cyaratewe n'ibiza byinshi nk'izamuka ry'amazi yo mu nyanja, imihindagurikire y'ikirere, n'iruka ry'ibirunga bikomeye.
Uretse kuba ifatwa nk'imwe mu nyamaswa ziteye ubwoba cyane mu bwami bwa dinosaur, T. rex izwiho imiterere yayo yihariye ndetse n'amateka yayo y'ubwihindurize. Ubushakashatsi bwa siyansi bwagaragaje ko T. rex yari ifite imiterere y'umutwe ifite ubukana n'imbaraga, bigatuma ibasha gutsinda umuhigo wayo ikubita umutwe idakomeretse. Byongeye kandi, amenyo yayo yari afite ubushobozi bwo kwihuza n'ibindi, bigatuma ibasha guca ubwoko butandukanye bw'inyama byoroshye.
Rero, T. rex yari imwe mu biremwa bikaze cyane mu bwami bwa dinosaur, ifite ubushobozi bukomeye bwo guhiga no gukina. Nubwo yazimye mu myaka ya za miriyoni ishize, akamaro kayo n'ingaruka zayo kuri siyansi n'umuco bya none biracyari ingenzi, bitanga ubumenyi ku mikorere y'ubwihindurize n'ibidukikije karemano by'ibinyabuzima bya kera.
