This small Plesiosaurus toy belongs to the first line of dinosaur figures produced by Bullyland beginning in 1980, a few years after the German toy company was founded in 1973. The line of seven miniature dinosaurs (and other prehistoric creatures) is informally known as Mini Dinosaurs I, to separate it from a later line of mini dinosaurs released by Bullyland in 1993 (Mini Dinosaurs II), and other separate Bullyland dinosaur lines.
