H5N1 squad of palaeontologists, led yesteryear University College Cork (UCC) in addition to including the University of Bristol, convey discovered novel sources of the paint melanin, calling for a rethink of how scientists reconstruct the color of fossil birds, reptiles in addition to dinosaurs.

The study, published inwards the magazine Nature Communications, is led yesteryear UCC's doctor Maria McNamara inwards collaboration amongst her Ph.D. educatee Valentina Rossi, doctor Paddy Orr from University College Dublin in addition to an international squad of palaeontologists from the Britain in addition to Japan.
The squad studied internal tissues inwards modern frogs amongst powerful microscopes in addition to chemic techniques to present that internal melanosomes are highly abundant.
doctor McNamara said: "This way that these internal melanosomes could brand upwards the bulk of the melanosomes preserved inwards roughly fossils."
The squad too used decay experiments in addition to analysed fossils to present that the internal melanosomes tin hand the sack leak into other trunk parts during the fossilization process—like snowflakes within a snowfall globe, according to doctor Orr.
There is a way, however, to say the departure betwixt melanosomes from internal organs in addition to the skin.
doctor McNamara added: "The size in addition to shape of peel melanosomes is unremarkably distinct from those inwards internal organs. This volition permit us to create to a greater extent than accurate reconstructions of the master colours of ancient vertebrates."
