From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Pteranodons (プテラノドン, Puteranodon; FUNimation "Pterodactyls") are Animal-type Earthlings.
Pteranodons were huge flying reptiles who lived around Mount Paozu, but were also seen in many other locations on Earth. A Pteranodon captured Bulma Brief in "Bulma and Son Goku", but was killed by Son Goku with a hit over the head with the Nyoibou. A Pteranodon was seen before Goku's encounter with the Bear Thief in "The Turtle Hermit's Kinto Un". It is possible that it was the same one that had captured Bulma, although that one had had his head crest broken off and fallen from a long distance in the sky to a ravine down below. A Pteranodon attacked Namu in "The Roaming Lake", but was knocked out cold by Goku with a hit over the head with the Nyoibou.
