A stunning example of an iridescent calcite multi-ammonite fossil of the species Psiloceras planorbis from North Somerset, UK.
The piece of limestone matrix measures 102 mm (4 inches) tall and contains multiple beautiful fossil ammonites that are all well preserved and have been prepared out of the rock to reveal the whole shells, which display some stunning iridescent colours that change depending on the angle that the fossil is viewed at, with red and copper colours dominating. The ammonites are on different levels in the rock as they are from slightly different layers, giving a nice three dimensionality to the piece. The fossil weighs 340 grams and has a cut-flat base to allow it to stand freely for display.
Around 200 million years old (Hettangian, Early Jurassic), this fossil would make a wonderful addition to any collection.
