ଡାଇନୋସର ଗୁଡ଼ିକ ହେଉଛନ୍ତି ଡାଇନୋସୋରିଆ Cladeର ଏକ ବିବିଧ ପ୍ରାଣୀ ପ୍ରଜାତି । ସେମାନେ ପ୍ରଥମେ ଟ୍ରାଇଆସିକ (Triassic) ଯୁଗରେ ଦେଖାଯାଉଥିଲେ , ପାଖାପାଖି ୨୩୦ ନିୟୁତ ବର୍ଷ ପୂର୍ବେ । ଜୁରାସିକ ଯୁଗର ଆରମ୍ଭରୁ (୨୦୦ ନିୟୁତ ବର୍ଷ ପୂର୍ବେ), କ୍ରେଟାସିଅସ ଯୁଗର ଶେଷ ପର୍ଯ୍ୟନ୍ତ (୬୫.୫ ନିୟୁତ ବର୍ଷ ପୂର୍ବେ) ସେମାନେ ସବୁଠାରୁ ପ୍ରଭାବଶାଳି ସ୍ଥଳଚର ଥିଲେ । Cretaceous-Paleogene extinction event ଯୋଗୁଁ ମେସୋଜୋଇକ ଯୁଗର ଶେଷ ବେଳକୁ ଅଧିକାଂଶ ଅଧିକାଂଶ ଡାଇନୋସର ପ୍ରଜାତି ବିଲୁପ୍ତ ହୋଇସାରିଥିଲେ । ଜୀବାଶ୍ମ ରେକଡ଼ ଅନୁଧ୍ୟାନରୁ ଜଣାଯାଏ ଯେ, ପକ୍ଷୀମାନଙ୍କର ଉଦ୍ଭବ ଜୁରାସିକ ଯୁଗରେ ଥେରୋପୋଡ଼ (theropod) ଡାଇନୋସରମାନଙ୍କଠାରୁ ହୋଇଥିଲା ଏବଂ ଆଧୁନିକ ଶ୍ରେଣୀବଭାଗ ବ୍ୟବସ୍ଥାରେ ସେମାନଙ୍କୁ ଡାଇନୋସରମାନଙ୍କ ଏକ ଉପ-ବିଭାଗର ମାନ୍ୟତା ଦିଆଯାଇଥାଏ ।^[୧]^[୨] କିଛି ପକ୍ଷୀ ୬୫ ନିୟୁତ ବର୍ଷ ପୂର୍ବେ ହୋଇଥିବା ଏହି ବିଲୁପ୍ତ ପ୍ରକ୍ରିୟାରୁ ବର୍ତ୍ତି ଯାଇଥିଲେ ଓ ସେମାନଙ୍କ ବଂଶଧରମାନେ ଡାଇନୋସରଙ୍କ ପିଢୀକୁ ଆଜି ପର୍ଯ୍ୟନ୍ତ ନେଇ ଆସିଛନ୍ତି ।

ଯଦିଓ ଡାଇନୋସର ଶବ୍ଦର ଅର୍ଥ "ଭୟଙ୍କର ଝିଟିପିଟି" (terrible lizard) , ପ୍ରକୃତରେ ଏହା ଏକ ଝିଟିପିଟି ପ୍ରଜାତିର ଜୀବ ନୁହେଁ । ଏମାନେ ସରୀସୃପମାନଙ୍କର ଅନ୍ୟ ଏକ ପ୍ରଜାତି ଅଟନ୍ତି ।

ନାମକରଣ
