Red colour found in an ancient fossil for the first time

A global team of researchers has detected chemical traces of red-coloured pigment in a well-preserved fossil of a 3-million-year-old extinct field mouse species for the first time ever, using X-ray spectroscopy. The around seven-cm-long field mouse, nicknamed “Mighty Mouse”, was found to have brown to reddish colour fur on its back and sides while its stomach-area was white.
