Short summary
Several British specimens corresponding to shells of small pleurosternid turtles (Lower Cretaceous) are analysed in detail here. Due to the scarce knowledge available to date about these specimens, their taxonomic status was doubtful. A detailed study through qualitative and quantitative approaches is performed. The results provide evidence of a significant range of shape variability because of the ontogeny. Thus, their attribution to juvenile individuals of Pleurosternon bullockii is justified.
