Pterosaur melanosomes support signalling functions for early feathers

HIGHLIGHTS

• who: Aude Cincotta from the (UNIVERSITY) have published the research: Pterosaur melanosomes support signalling functions for early feathers, in the Journal: (JOURNAL) of 22/Oct/2021
• what: The authors report the presence of diverse melanosome geometries in the skin and simple and branched feathers of a tapejarid pterosaur from the Early Cretaceous found in Brazil. In Tupandactylus, melanosomes from the skin fibres in the crest, monofilaments and branched feathers differ significantly in geometry Origins for visual signalling in feathers the study has important implications for understanding the evolution of melanin-based colouration.
