A stunning example of a calcite ammonite fossil of the species Psiloceras planorbis from North Somerset, UK.
The piece of limestone matrix measures 180 mm (7.1 inches) wide and the largest fossil ammonite measures 84 mm (3.3 inches) across, which is very large for this species. The ammonites are well preserved and have been prepared out of the rock to reveal the whole shells and the matrix has been aesthetically shaped for display. The shells displays some nice subtle iridescent colours with silvery sheens and red flashes that appear as the viewing angle changes. The fossil weighs 925 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.
