A fossil ammonite (an animal related to octopus and squid) found at East Worldham, Hampshire. It is from the Cretaceous period (Upper Greensand Formation) and is between 112 and 99 million years old.
Ammonites lived in the sea, and their shells, which were mainly coiled, were divided internally into chambers. The earliest ammonites lived about 400 million years ago and they became extinct about 65 million years ago.
This ammonite is an unusual specimen as it still has the rostrum (an extension coming off the main shell) in place. It was found by William Curtis, the founder of the Curtis Museum, Alton, who discovered that ammonites known during Victorian times as ‘Ammonites rostratus’ had three different types of rostrum. Through studying a number of specimens William Curtis discovered that the different rostra ‘may indicate specific differences’ or different species.
This will be on display at Milestones, Basingstoke during the Lego Lost World exhibition 26 February to 27 April 2014.
