Dinosaurligama elidityanisiweyo lezidalwa ngokulandelelana ngokubanzi kweedinosaurs (igama lesayensi:IDinosauria), iqela lezilwanyana eziziintlobo ngeentlobo zomhlaba ezavela kwiXesha leMesozoic, kwaye ikwayeyona paleontology idumileyo ngaphakathi kwendawo yokuqonda komntu.Iidayinaso zezona zilwanyana zinethambo lomqolo zilawula kwaye ziphumelele kwixesha leMesozoic kwimbali yomhlaba.Baqala ukuvela kwixesha le-Triassic kwiminyaka ezigidi ezingama-230 eyadlulayo kwaye balawula i-ecosystem yomhlaba kwi-100 yezigidi ezingama-400 yeminyakaIxesha 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 kwedayinaso mass etinction) eyenzeka kwi-66 yezigidi zeminyaka eyadlulayo, kwashiya kuphela uhlobo lweentaka iidayinaso 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.
