Microraptor
Like Archaeopteryx , Microraptor was about the size of it of a crow and had tooth , pincer and feathers on all four limbs that it may have used to glide between tree . However , it is more closely related to dinosaurs than to shuttle , and many scientist believe that this 124 million - year - old dinosaur may be the long - sought pretermit link between the two group .
Ornithomimus
Ornithomimus , whose name means " skirt - mimic , " was an ostrich - like dinosaur that lived around 70 million old age ago . It was about 10 - 15 pes long — most of which was taken up by its neck opening and tail — and had a horny nib , a small head and empty bone . It was truehearted and agile , and may have been able to run at speeds of up to 70 mph as fast as a Acinonyx jubatus .
Oviraptor
Oviraptor was a pocket-sized razzing - like animal that lived about 80 million year ago . It had long slender leg , squat , strong blazon , and a short toothless beak . It also had a belittled French horn - similar crest that it probably used for felt up displays . Its name in Latin means " testis thief , " because the first Oviraptor fossil ever discover was establish near what was recollect to be a Protoceratop ’s nest . However , closer depth psychology later revealed that the nest contained Oviraptor eggs . This has pass to Oviraptor ’s trope - makeover in recent geezerhood from that of an egg abductor to a nurturing parent .
Rahonavis
This Corvus corax - sized animate being belonged to the same radical of dinosaurs as Velociraptor , but it had many bird - like features . Rahonavis lived about 80 million geezerhood ago and had a retractable " sickle - claw " on the mediate toe of each foot . It had feather wing like a shuttlecock but a long bony tail like Archaeopteryx .
Sinornis santensis
About the size of a sparrow , Sinornis santensis dwell about 135 million old age ago and was probably an splendid flier that was equal to of free burning flight of stairs . It†™ s slender leg and piercing claw were poorly - equipped for take the air but it was able to perch and to skitter up and down trees . It was more hiss - like than its ascendent Archaeopteryx , but it still had teeth and a scant snout instead of a dead on target nozzle .
Sinornithosaurus
Sinornithosaurus was the fifth and most bird - alike feathered dinosaur specie ever to be discovered . It lived about 125 million years ago and was a dromaeosaurid . Its discovery strongly suggest that other dromaeosaurids may have also had feathers . Some scientist believe that its find is proof that feather first developed in quick - footed , reason - dwelling dinosaur , rather of those that lived in tree .
Sinosauropteryx
Like Micropteryx , Sinosauropteryx was more closely related to dinosaur than to birds , and yet it intelligibly had feathers . It was about 3 feet long and experience in China about 125 million age ago . It had long leg , short arms , a foresighted bony tail and it probably consume insect and little animate being .
Troodon
Troodon had one of the largest brain - to - body sizing ratio of any known dinosaur and it is believed to have been one of the most thinking dinosaurs that ever populate . Its large , slightly forward facing center suggest that it was a nocturnal creature with first-class depth percept and it had long arms that it could fold up back like a bird . It lived about 70 million year ago .
Velociraptor
Velociraptor is one of the most raspberry - like dinosaurs ever discovered . It was modest and profligate , and the reaping hook - form claw on the second toe of each foot made it a redoubtable predator . A particular pearl in its carpus allowed it to swivel its carpus sideways in a pother motion and to fold its limb against its body like a bird . This movement set aside it to snap its arms forward to snap up fleeing quarry and is an crucial part of the flight separatrix in modern hiss .
