A stunning example of an ammonite fossil of the species Psiloceras planorbis from North Somerset, UK.
The piece of limestone matrix measures 85 mm (3.3 inches) tall and contains four ammonites, three on one side and one on the other. The three ammonites washed together on the Jurassic seafloor along with an unusual bivalve shell. It is unusual to get assemblages of this species in one piece like this. The matrix is original and has been shaped for display and has a cut-flat base to allow it to stand freely by itself. The ammonites are well preserved and have been prepared out of the rock to reveal the shells, which display some subtle iridescent colours with a bronzy sheen.
The fossil weighs 145 grams. 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.
