Description
SUPERB CANADIAN IRIDESCENT AMMONITE
Placenticeras meeki
Late Cretaceous
Bearpaw Formation, southern Alberta, Canada
Only in the small Bearpaw formation, stretching over parts of Montana, Alberta and Saskatchewan, along the eastern slopes of the Rocky Mountains, does this remarkable instance of pseudomorphology occurs. The ammonite's shell comes into contact with trace elements such as manganese, strontium, titanium, barium and others, manifested in the dazzling colors displayed here. As with most specimens from this locale, the present example is naturally flattened, but retains a complete covering of the transformed nacre, finely preserved on both sides in fiery shades of red, orange, and electric green, and highlighted with shimmering golden yellow, 16 inches wide, with a wooden display stand.
