Beschreibung:

Placenticeras costatum Upper Cretaceous Bearpaw Formation, Southern Alberta, Canada Coveted by collectors the world over, the 75- to 70-million-year-old ammonite specimens from the Bearpaw Formation display a spectacular palette produced by light interference within the shells' layers; these layers are formed of the ammonite's own mother-of-pearl which has been perfectly fossilized. The resulting brilliant material is often referred to as ammolite, one of only two fossil materials classified as a gemstone (the other being amber.) This complete, beautifully preserved example in matrix exhibits red, yellow, green and the rarely seen blue coloration, which is highly prized by collectors. A spectacular piece; the luminous colors glimmer in dramatic contrast to the deeply colored matte shale. Measures 14 x 15in; Specimen measures 8in
