Penguins ply the southern seas of this timeline and ours and are known as Paleocene fossils from both worlds. This would suggest that the sphenisciformes had already appeared by the end of the Cretaceous or that presence/absence of the K-T event had little impact on the evolution of penguins, probably on small islands in the New Zealand archipelago. Penguins have, thus, evolved along more or less the same lines in both worlds. However, in addition to familiar penguins, Spec's sphenisciformes include a far greater variety of body forms, some of which include the largest of all avians.
