Dinosaur is the debut studio album by the alternative rock band Dinosaur Jr. It was released in 1985 on Homestead Records. The album exhibits a folkier side of the band than on future releases, but some of the tracks on the album showed off a much heavier, more hardcore punk-based side to the band in songs such as "Does it Float", "Mountain Man", and "Bulbs of Passion".
The album was originally released when the band was still known simply as Dinosaur, before a lawsuit forced the name change to Dinosaur Jr. Therefore, it was originally a self-titled album, but subsequent issues kept the Dinosaur title.
