The Coraciiformes are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes (and toes 3 & 4 fused at their base), though in many kingfishers one of these is missing.

The extinct Messelirrisor is a genus of Bucerotiformes, the sole representative of the family Messelirrisoridae. They were tiny hoopoe-like birds that were the earliest representatives of the hoopoe/wood-hoopoe lineage, and they were among the predominant small forest birds of Central Europe during the Middle Eocene (some 49-37 mya). Fossilized remains of Messelirrisor have been found in the Messel Pit of Hesse, Germany. thumbnail|left|Life restoration

Ueekenkcoracias is an extinct genus of bird from the Huitrera Formation of Patagonia. Initially assigned to Coracii, similarities have instead been noted with Palaeopsittacus, and it may instead be more closely related to Strisores, the clade including hummingbirds, nightjars, and swifts. One species of Ueekenkcoracias, U. tambussiae, has been named.

Primobucco is an extinct genus of bird placed in its own family, Primobucconidae. The type species, Primobucco mcgrewi, lived during the Lower Eocene of North America. It was initially described by American paleo-ornithologist Pierce Brodkorb in 1970, from a fossil right wing, and thought to be an early puffbird. However, the discovery of a further 12 fossils in 2010 indicate that it is instead an early type of roller.
