Palaeontologists in Brazil have studied the head of a pterosaur named Tupandactylus imperator, andclaim to have found “simple and branched feathers” on the back of its crest. They examined these with an electron microscope and found they contained various shaped melanosomes – tiny vesicles containing the pigment melanin. Variation in the shape of melanosomes is […]
