Emperor Penguins are the largest penguin species still in existence and are between 3.6 and 4.3 feet tall, weighing around 50 pounds or more. For comparison, Waimanu are a bit smaller than Emperor Penguins. These birds were between 22 and 66 pounds. The fossils show that the Waimanu was between 2 and 3.2 feet tall. For the Waimanu, this holotype specimen includes a partial skeleton. This is a single specimen that most closely represents what scientists believe the animal actually looked like. When describing newly discovered species, researchers rely on a holotype specimen. Scientists rely on fossils to reconstruct the appearance of ancient animals, including the Waimanu.
Understanding how they fit into the scientific classification system and how their descendants evolved and branched off into different species is a key part of study for researchers who want to learn more about the animal world. These ancient birds are members of the phylum Chordata and kingdom Animalia. This includes all birds, which are characterized scientifically by the presence of feathers, beaks, laying eggs, and a lightweight skeleton that is ideal for flight. The Sphenisciformes include modern penguins such as the Emperor Penguin, Galapagos Penguin, and Macaroni Penguin. The only known species is the Waimanu manneringi. The Waimanu is actually a genus within the Sphenisciformes order. Waimanu Species, Types, and Scientific Name Studying Waimanu fossils helps scientists learn more about how birds evolved. Unlike penguins, they did not live their lives in the water. Like their descendants, they were not able to fly. These birds lived during the Paleocene epoch and were the ancestors of modern-day penguins. If you like penguins, you’ll love the now-extinct Waimanu.
