A stunning example of an ammonite fossil of the species Psiloceras planorbis from North Somerset, UK.
The piece of limestone matrix measures 90 mm (3.55 inches) tall and contains a complete ammonite, which measures 38 mm (1.5 inches) across. The shale matrix has been shaped and has a cut-flat base to allow it to be displayed freely standing.
The ammonite is very well preserved and has been prepared out of the rock to reveal the shell, which is pure white with a pearlescent sheen, making it stand out well against the darker background. It weighs 124 grams.
Around 200 million years old (Hettangian, Early Jurassic), this fossil would make a wonderful addition to any collection.
