A stunning example of an uncommon calcite ammonite fossil of the species Strigoceras truelli from the Jurassic Coast beach of Burton Bradstock, Dorset UK.
The fossil ammonite measures 175 mm (6.9 inch) across. The ammonite is very well preserved and has been prepared out of the rock to reveal the whole shell, including the deep centres that this genus is known for. The detail in the ornamentation is great, and the mottled colour is beautiful. The shell is filled with crystalline calcite in the internal gas chambers, which are exposed on the edge of the keel. A great example of an uncommon species and impressive in the flesh. The fossil weighs 2120 grams and has a cut-flat base to allow it to stand freely for display. These ammonites are hard to find in this condition due to a lack of erosion on this part of the coast. They make wonderful display items and look great as interior design features.
Around 168 million years old (Bajocian, Middle Jurassic), this fossil would make a wonderful addition to any collection.
