The abstract states the a sampling bias exists and makes the following comment: "Histological analysis suggests that very small/small morphs are immature individuals rather than species in which adults were small-bodied." Unfortunately the paper is paywalled but this must raise to question how many of the smaller pterosaurs species that are named in the KK were early ontogenetic stages of larger pterosaurs. Not surprised considering that there are 10 named an

Method to determine shark development stage from teeth
David in Japan posted a topic in Questions & Answers
