A stunning example of an ammonite fossil of the species Psiloceras planorbis from North Somerset, UK.
The piece of limestone matrix measures 62 mm (2.45 inches) across and the fossil ammonite measures 32 mm. The ammonite is well preserved and has been prepared out of the rock to reveal the whole shell, which displays some nice iridescent colours with rainbow flashes that change colour as the angle the fossil is viewed from changes. The fossil weighs 45 grams and has a cut-flat base to allow it to stand freely for display. These ammonites make wonderful display items and are real conversation starters.
Around 200 million years old (Hettangian, Early Jurassic), this fossil would make a wonderful addition to any collection.
