Dinosaur (Kesha song) "Dinosaur" is a song by American recording artist and songwriter Kesha, taken from her debut studio album "Animal" (2010). The song was written by Kesha in collaboration with Max Martin and Shellback; the latter two also produced the song, while all three are responsible for the instrumentation. The song's conception stems from an encounter Kesha had with an older man that had been hitting on her, which she compared to a prehistoric dinosaur. The lyrics discuss an older man that is attempting to hit on a younger female, which is ultimately rejected. The song received generally negative reviews from music critics. Upon the release of "Animal", "Dinosaur" charted on the South Korea Gaon International Chart, peaking 107 respectively.
