There were three different types of dinosaurs produced. I'm unsure of the exact dinosaur type, so have used their group names for reference purposes.

Ceratopian

The ceratopian came in two sizes and two colours. The large yellow version (approx 16" long) had a piece of fur on its and head which could be flipper over, the smaller version (approx 10" long) didn't have this and also varied down the sides too.

The pink ceratopian most probably came in two sizes too, this one being the larger version with the head and chin flap.

Stegosaurus

The stegosaurus was approx 9" high and 11" long and also came in two colours.

Carnosaur

The carnosaur was approx 12" high. Like the others this also came in two colours.
