Scientists have successfully reconstructed the bones of 25 million years old penguin. They have found that those Kairuku pnguins were the tallest and fattest of all the known penguins.
"Kairuku was an elegant bird by penguin standards, with a slender body and long flippers, but short, thick legs and feet," said co-author Dr. Dan Ksepka, from North Carolina State University, US.
"If we had done a reconstruction by extrapolating from the length of its flippers, it would have stood over 6ft tall. In reality, Kairuku was around 4ft 2ins tall or so."
