A stunning example of an ammonite fossil of the species Psiloceras planorbis from North Somerset, UK.
The piece of limestone matrix measures 80 mm (3.15 inches) across and the fossil ammonite measures 30 mm across. The ammonite is well preserved and has been prepared out of the rock to reveal the whole shell. The shell displays some beautiful iridescent colours that change as the angle the fossil is viewed from changes with a nice sheen. The fossil weighs 30 grams and is on a thin piece of shale.
Around 200 million years old (Hettangian, Early Jurassic), this fossil would make a wonderful addition to any collection.
