This incredibly rare Lower Liassic ammonite is approximately 208 million years old and was collected in 1969! This is a highly restricted locality and collecting is forbidden nowadays. There are very few of these, the earliest of the ammonites to come out of this location, the rest being in Ulster Museum. The same ammonites appear on the Somerset coast as crushed irridescent ammonites. Where these ammonites were collected is the most westerly lias in Europe. One for the serious collector of rare ammonites!!
