50 Pence - Charles III Jurassic Britain - Scelidosaurus

Scelidosaurus harrisonii was first described by Richard Owen in 1861 from Dorset specimens — making it one of the earliest dinosaurs formally named in Britain. It sits at a genuinely interesting point in ankylosaur and stegosaur evolutionary history, though its exact phylogenetic position was debated for over a century. The Isle of Man has no fossil record of its own for this animal; the choice reflects commercial appeal rather than local paleontological heritage.
