A stunning example of a calcite ammonite fossil of the species Asteroceras obtusum from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of limestone matrix measures 95 mm (3.75 inches) tall and the fossil ammonite measures 38 mm (1.48 inches) across. The ammonite is well preserved and has been prepared out of the rock to reveal the whole shell on both sides. This means that when a light is shone behind the fossil, the shell becomes translucent and glows a fiery red and orange colour. The ribs are very finely defined, and the colour is beautiful: a mix of mottled browns, creams, and grey. A great example of a popular species and impressive in the flesh. The fossil weighs 315 grams and a cut flat base to allow it to stand freely on its own for display.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
