Lot Details
Russian Aberrant Ammonite
Ancyloceras matheronianum
Cretaceous
Russia

Most ammonites exhibit the familiar tight spiral shape that is so well known, but some ammonites, known as aberrant (heteromorphic) ammonites, began to straighten out, forming a variety of odd, interesting shapes. Why this happened after more than 200 million years of spiral shaped species is unknown, but some species did change 70-120 million years ago. The present large and spectacular ammonite is virtually complete. Its original white mother-of-pearl shell coating has fossilized to an iridescent brown and tan with splashes of white still present.
