Many of the best toys are the ones that can be rebuilt or transformed in some way. Bone Age was an interesting series where the skeletons of dinosaurs could be rebuilt into different shapes or combined with other skeletons and/or the weapons. They were pretty hefty toys both in size and weight. The line was divided into three clans, with each clan having three skeletons.
Made by Kenner between 1987 and 1988, Bone Age was released at a time when they toy manufacturer was struggling with sales. Their successful Ghostbusters line was coming to the end of its life and their Sky Commanders series had failed to catch much attention. Bone Age was Kenner's attempt to do something radically difficult in a hope to turn around poor profits. Unfortunately, it failed to succeed and it never made it past its first series.
