"None that prove one became another . Of course dinos , birds , and fish exist and scientist study them -or their remains as with dinos ."
"Fish to Amphibian supporting evidence frmo here : Fish/Amphibian Transition from primitive bony fish to amphibians : Paleoniscoids again ( e.g . Cheirolepis ) Osteolepis -- one of the earliest crossopterygian lobe-finned fishes , still sharing some characters with the lungfish ( the other group of lobe-finned fish ) . Had paired fins with a leg-like arrangement of bones , and had an early-amphibian-like skull and teeth . Eusthenopteron ( and other rhipidistian crossopterygian fish ) -- intermediate between early crossopterygian fish and the earliest amphibians . Skull very amphibian-like . Strong amphibian-like backbone . Fins very like early amphibian feet . Icthyostegids ( such as Icthyostega and Icthyostegopsis ) -- Terrestrial amphibians with many of Eusthenopteron 's fish features ( e.g. , the fin rays of the tail were retained ) . Some debate about whether Icthyostega should be considered a fish or an amphibian ; it is an excellent transitional fossil . Labyrinthodonts ( e.g. , Pholidogaster , Pteroplax ) -- still have some icthyostegid features , but have lost many of the fish features ( e.g. , the fin rays are gone , vertebrae are stronger and interlocking , the nasal passage for air intake is well defined . ) And while nothing is ever proven 100 % in science , the link between fish and amphibians is pretty conclusive . Evidence for dino to bird evolution just keeps mounting and at present it is the best supported theory . Just look at the recent discovery of an oviraptorosaurian dinosaur with 2 eggs still in it 's body , two very bird like eggs ..... See here : dinoeggs So once again , while not proven 100 % , dino to bird evolution is the best supported theory . Do you have anything that is better supported ? ? ?"
