Highlights

  • Made by tcustom
  • Materials: pewter, stainless steel

Several thousand years ago, someone's eye chanced across a boulder, and saw something out of place... This ancient human tapped and prodded the mysterious stone until suddenly part fell away, revealing a beautiful, and clearly incongruous, perfect spiral... surely not of earthly origin!

This ammonite concretion keychain celebrates one of nature's enduring wonders. How amazed would ancients have been to know that "ammonites" (named for the ram's horns sometimes pictured on the god Ammon) were, in fact, the preserved shells of cephalopod molluscs (related to squid and octopus)? Although no ammonites live today, they left behind a wonderful legacy of fossils, which are often found, as depicted here, in the form of a "nodule", or "concretion."

This ammonite concretion keychain is assembled in three articulating parts, evoking the process of discovery. Great for paleontologists and other fossil hunters, as well as fans of squid, octopus, nautiloids, and the other amazing cephalopods!
