Short summary
With the support of CT data, a morphometric analysis was performed with the aim of investigating the rostrum size differences between two Toarcian belemnite accumulations. A decrease in size from the Early Toarcian to the Middle Toarcian is recognized. It is also demonstrated that diameter-based measurements or maximum preserved length are not reliable proxies for rostrum size, and therefore apical length or three-dimensional approximations are more advisable.
