Episode 52: Melanin

Melanin is a pigment that is found across the animal kingdom. Melanosomes, the organelles that contain melanin, have been found preserved in fossil feathers and melanosome shape has been used to infer the original colors of birds and dinosaurs. Today we’re talking to Caitlin Colleary whose paper - on her Masters research at the University of Bristol - delves into detail regarding the structural and chemical preservation of melanin and describes the color of a fossil mammal for the first time.
