A freshly discovered penguin fogy unveil a bird twice as great as an Emperor penguin and with color radically different from the familiar black and white feature all modern penguin share … but this Water King was already the everlasting swim fowl .
The fossil was detect in Peru and has been classified as Inkayacu paracasensis , but its less courtly name is Water King . It ’s not hard to see why – at five feet tall , it was twice the size of it of the large life penguin . Of course , we might not immediately realise this bird as a penguin , at least if we ’re travel strictly by the familiar tux - like colors of its posterity . rather of a black and white feather , this penguin had a mix of reddish - chocolate-brown and gray feathers .
The people of colour of the feathering might seem like a relatively insignificant item , but it actually provides all-important insight into how penguin grow . While its colors were different , the structure of the Water King ’s plume were identical to those of modern penguins . The annex feathers were densely carry together to take shape the slopped , narrow flippers so crucial to swimming , while the organic structure feathers possessed streamline structures that also aid in swimming . This means he social system of the penguin feathers acquire very betimes , but it was significantly later than penguins build up their traditional feather colors .
Feather vividness are make by tiny structures call melanosomes , which can create many different colors calculate on their size of it , shape , and how they ’re put together . Researchers have built up an across-the-board library of melanosomes and what color they grow , and this allowed them to reconstruct the color of the Water King ’s penguins .
Unlike the Water King and all other raspberry , modern penguins have giant melanosomes much adult than any others found in nature . These give them their distinctive colors , but the fact that the Water King did n’t have them suggests they did n’t evolve strictly to help with swimming . Researchers theorise these helped penguins camouflage themselves from seals and other predator .
Researcher Jakob Vinther summarise up the grandness of his team ’s workplace with admirable honesty about what ’s really of import :
“ Insights into the color of extinct organisms can bring out clew to their ecology and behavior . But most of all , I think it is simply just cool to get a aspect at the color of a singular extinct organism , such as a giant fossil penguin . ”
