Dinosaurligama elidityanisiweyo lezidalwa ngokulandelelana ngokubanzi kweedinosaurs (igama lesayensi:I-Dinosauria), iqela lezilwanyana eziziintlobo ngeentlobo zomhlaba ezavela kwiXesha leMesozoic, kwaye ikwayeyona paleontology idumileyo ngaphakathi kwendawo yokuqonda komntu. IiDinosaurs zezona zilwanyana zibalaseleyo nezichumileyo kwixesha leMesozoic kwimbali yomhlaba. Baqala ukuvela ngexesha le-Triassic kwiminyaka engama-230 yezigidi eyadlulayo kwaye balawula i-ecosystem yomhlaba kwi-100 yezigidi ze-400 yezigidi zeminyakaIxesha leJurassic kunye neCretaceous. Kangangamawaka eminyaka, wabeka unyawo esibhakabhakeni naselwandle. Iidayinasozihlala zohlulwe zibe ziindidi ezimbini: "ezingezontakaiidinosaur" kunye "needinosaur zeentaka". Zonke ezingezizo iintakaidinosauri-urs, i-anti-bird subclasses kunye ne-fantail subclasss kuhlobo lweentakaiidinosauryafa kwisiganeko sokuphela kweCretaceous extinction (ukuphela kweedayinaso mass etinction) eyenzeka kwi-66 yezigidi zeminyaka eyadlulayo, kushiyeke kuphela uhlobo lweentaka phakathiiidinosaur, iOrnithidae yasinda, yaguquka yaba ziintaka yaza yaphumelela ukuza kuthi ga kulo mhla.
Ubudlelwane phakathi kwezinye izilwanyana ezirhubuluzayo kunyeiidinosaur
Uninzi lwezilwanyana ezirhubuluzayo zangaphambi kwembali zihlala zichongwa ngokungacwangciswanga njengeiidinosaurluluntu ngokubanzi, olunje:IiPterosaurs, IiPlesiosaurs, iiMosasaurs, iiIchthyosaurs, iiPelycosaurs (Dimetrodonkunye ne-Edaphosaurus), njl., kodwa ngokwembono yenzululwazi engqongqo Ezi azikhoiidinosaur. Iidayinaso nazo ziphosakele kwizinyanya zamacikilishe kunyeingwenyaiidililikodwa ngokwenene,iidinosaurkwayeiingwenyazavela ngokuhambelana, kwaye zinento encinci yokwenza namacikilishe. Ngokuchasene noko, iintaka zanamhlanje zinokuthathwa njengeiidinosaur zokwenyanikwisayensi.
