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 250 mm (9.85 inches) tall and the fossil ammonite measures 102 mm (4.05 inches) across, which is a good size for this species. The ammonite is well preserved and has been prepared out of the rock to reveal the details of the shell. The ribs are very finely defined, and the deep, mottled-yellow and brown colour is beautiful. there is also a smaller ammonite of the species Promicroceras planicosta at the top of the matrix.
The matrix has been shaped to make it a sculptural piece that displays wonderfully. A great example of a popular species and impressive in the flesh. The fossil weighs 2535 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.
