Ammonite Enamel Pin (Ammonoidea)

Before humans, before mammals, before most of what we’d recognize today, Ammonoidea ruled the seas in coiled, chambered shells that could be as small as a button or rival a human in size. These cephalopods—relatives of modern squid and octopuses—thrived for 300 million years before vanishing with the dinosaurs 66 million years ago. Their shells, with perfect logarithmic spirals and intricate ridges, have fossilized into some of the most iconic relics in paleontology. This hard enamel pin captures their hypnotic symmetry and ancient presence in polished metal and enamel—no fossil dig or Mesozoic seafloor required.

Specs:

• Premium metal base with polished hard enamel fill
• Secure clasp so your ammonite doesn’t “spiral away”
• Size: 35.5 x 31.5mm
• Zero chance of washing up in your rock tumbler

Perfect for fossil hunters, paleontology fans, and anyone who loves their accessories with a swirl of deep time.
