Dr. Field speculates that penguins shrank in size over time as large mammals began to enter the sea and compete with them for resources.
He hopes that fossil discoveries made in the future will reveal more information about the prehistoric birds.
“Kumimanu fordycei would have been an utterly astonishing sight on the beaches of New Zealand 57 million years ago, and the combination of its sheer size and the incomplete nature of its fossil remains makes it one of the most intriguing fossil birds ever found,” he said.
