Description
This listing features a large and beautifully preserved 6-inch ammonite fossil of Sonninia prequinquosum, discovered in the Jurassic Coast locality of Burton Bradstock, Dorset, UK. This specimen comes from the Inferior Oolite Group, dating to the Middle Jurassic, and is a fine representation of classic British ammonite preservation.
Sonninia is known for its moderately involute shell and ribbed whorls, often showing a slightly keeled venter and distinctive morphological features that provide valuable insights into Middle Jurassic marine life. This fossil has been carefully cleaned and prepared to showcase its naturally detailed shell, offering both scientific and aesthetic value.
