Opabinia regalis, from the Burgess Shale, replica Iguanodon Liopleurodon was not a dinosaurVery Rare Cast of this Burgess Shale Specimen. Cambrian Age, BC, Canada. This creature with its five eyes is a strange looking one indeed. Wielding a long flexible proboscis tipped with grasping spines, its reconstructed image was greeted with laughter as a pretty good joke when first presented at a scientific meeting in 1972. The strange looking reconstruction was soon confirmed, and this creature remains one of the oddities of the Burgess Shale
