This ammonite from Madagascar is a Cleoniceras. It dates from the Cretaceous period, around 120 million years ago. It is sawn in 2 and mounted on a rack mechanism with an oak base. By operating these brass gears, one can discover the complexity of the interior and even calculate its age! In fact, she grew from a partition all the phases of the moon: 29.5 days, in optimal conditions. This prehistoric shell was therefore a little less than 3 years old when it died, 120 million years ago. Scientific curiosity ... but above all aesthetic!
