**Paleontologists have described the heaviest penguin in history. It weighed 155 kilograms. The giant bird lived in New Zealand 55-60 million years ago.** [Largest-known fossil penguin provides insight into the early evolution of sphenisciform body size and flipper anatomy](https://www.cambridge.org/core/journals/journal-of-paleontology/article/abs/largestknown-fossil-penguin-provides-insight-into-the-early-evolution-of-sphenisciform-body-size-and-flipper-anatomy/8D4A78B2CA0A716134F8E60169A633FD) Paleontologists have found fossils of some of the largest penguins that have ever lived in New Zealand. These penguins lived 55-59 million years ago during the Paleocene era. They have discovered two new species of penguins, including one that was possibly the largest penguin to ever exist, weighing an estimated 148-159 kilograms. Another new species was slightly larger than the emperor penguin. These new discoveries help us understand the evolution of penguins and show that they reached their maximum size early in their history. How do you feel about penguins, @mr27.near?
