Megapaloelodusis an extinct genus of birds distantly related to flamingos. It belongs to the same family as the closely related genus Palaelodus, but was more specialized. Megapaloelodus represents a specialization of the lifestyle of Palaelodus, which apparently was more like a wading duck in behavior – long-legged but still able to swim with ease, possibly even diving a lot – than a modern flamingo. Megapaloelodus, on the other hand, seems to have been evolved into a true wading bird, convergent with the true flamingos.
