“…Ontogenetic dietary shifts, the changes in diet use occurring over the lifespan of an individual consumer, are a common habit in most invertebrates, fishes, amphibians and reptiles [50,51], such as crocodilians [52], snakes [53], lizards [54] and turtles [55]. This phenomenon was also reported in fossil archosaurs, such as dinosaurs [56,57] and pterosaurs and the latter was based on samples of pterosaurs in which one or more ontogenetic stages are absent or royalsocietypublishing.org/journal/rstb Phil.

Knowledge about the pterosaur diet and digestive system is limited, and there is little direct evidence in the fossil record. Here, we report two specimens of the wukongopterid Kunpengopterus sinensis , a juvenile and an adult, from the Late Jurassic Yanliao Biota of China with associated bromalites. Both of these concentrations are identified as emetolites, fossilized gastric pellets. These pellets contain scales of an unnamed palaeonisciform fish, confirming the pterosaur was a piscivore. It probably vomited the pellets, indicating the presence of two-part stomachs and efficient antiperistalsis in both juveniles and adults. Comparing the ganoid scales found in the pellets with those of complete fishes, it was possible to determine that the prey of the smaller pellet is an average-sized individual, while the prey of the larger pellet represents a large specimen. Kunpengopterus sinensis might have preyed on the same fish during ontogeny, with adults being able to feed on larger individuals. This article is part of the theme issue ‘The impact of Chinese palaeontology on evolutionary research’.

The pterosaur assemblage of the mid-Cretaceous Kem Kem Group of Morocco is reviewed. This analysis examines their taxonomy, palaeoecology and palaeobiology with comments on taphonomy. New material permits the rediagnosis of the azhdarchoids Alanqa saharica and Afrotapejara zouhrii. Several specimens are reported that do not fit within the paradigms of previously named taxa. They represent three distinct jaw morphotypes, but are not assigned to new taxa here. The assemblage is highly diverse, including four tooth-bearing taxa assigned to Ornithocheiridae and five named taxa and three additional morphotypes assigned to Azhdarchoidea. The Kem Kem Group assemblage is the most diverse for any pterosaur-bearing fluvial deposit and one of the most diverse of any pterosaur assemblage. The assemblage is heavily biased in terms of preservation with an as yet unexplained high abundance of jaw fragments. We highlight the importance of fragmentary material in pterosaur studies.
