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 83 mm (3.25 inches) tall and contains two ammonites, which measure 16 mm and 30 mm, making them both juveniles of this species.
The ammonites are well preserved and have been prepared out of the rock to reveal the whole shells. The ribs are very finely defined, and mix of colours is beautiful. A great example of a popular species and impressive in the flesh. The fossil weighs 75 grams and has 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.
