The first molecular grounds for a peppiness pigment in the fossil record has been described by palaeontologists at University College Cork . look at fossilfrogsthat date back 10 million years , the squad discovered the early known molecular grounds of phaeomelanin , arguably bring in these anurans the original peppiness .
The discovery will help future fossilist to ramp up a characterisation of the color profiles of extinct animals as it demonstrates how molecular analytic thinking can be utile when studyingfossilsin unveil paint like phaeomelanin .
“ This finding is so exciting because it puts palaeontologists in a better shoes to discover different melanin pigment in many more fossils , ” read Dr Tiffany Slater of UCC ’s School of Biological , Earth , and Environmental Sciences ( BEES ) and Environmental Research Institute ( ERI ) in astatement . “ This will paint a more exact picture of ancient creature colour and will answer important questions about the evolution of colour in animals . ”

wear in the dodo record for 10 million year is no mean feat , which is why the feasibility of drawing much from the biomolecular details has been questionable . However , theseginger frogsshow that it can be done , and could unfold new boulevard of investigation for researchers work on ancient specimen .
“ Fossils are always altered by the ravages of rut and pressure during burial , but that does n’t mean that we mislay all original biomolecular selective information , ” articulate Prof. Maria McNamara , also of BEES and ERI . “ Our fossilization experiments were the cay to understanding the chemistry of the fossils , and prove that traces of biomolecules can survive being fudge during the fossilisation process . There is huge potential to research the biochemical evolution of animals using the fossil criminal record , when we account for chemical substance change during fossilisation . ”
Curiously , the phaeomelanin pigment is now toxic to animals , but discovering the former known evidence of it is a good footmark toward realize what drove the emergence of ginger in the animal land .
“ Scientists still do n’t love how – or why – phaeomelanin evolved because it is toxic to fauna , but the fossil record book might just unlock the closed book , ” woodlouse resolve .
The study is published inNature Communications .
