A stunning example of an ammonite fossil of the species Psiloceras planorbis from North Somerset, UK.
The piece of limestone matrix measures 150 mm (5.9 inches) tall and the fossil ammonite measures 76 mm (2.98 inches) across, which is large for this species. The ammonite is well preserved and has been prepared out of the rock to reveal the whole shell. The shell displays some nice subtle iridescent colours with rainbow flashes when the angle the fossil is viewed from changes. The colours on this example are particularly bright and saturated for this species. The fossil weighs 1210 grams and has two cut flat bases to allow it to stand freely for display in multiple ways. These ammonites make wonderful display items and are real conversation starters. This is as good as this species gets!
Around 200 million years old (Hettangian, Early Jurassic), this fossil would make a wonderful addition to any collection.
