Yesterday my eldest son was on a mission - to return to a beach we had explored a few days earlier, this time clutching his fossil hunting kit put together by his geologist grandpa. In his wonderfully convincing 9 year old opinion, he had discovered an ichthyosaur vertebra and was determined to dig it out of the surrounding rock. My younger son got involved in the expedition as chief 'brusher' dusting away the chipped rock to keep the area clear for the task in hand. The banter between the two of them was wonderful - such enthusiasm and anticipation. Where was the rest of the sea monster?
