A kingfisher-like bird from Messel – Quasisyndactylus longibrachis Mayr

This tiny bird is thought to be the ancestor of the kingfishers or of the todies, or of both.

Quasisyndactylus longibrachis was very small, only about 10 cm long, its legs were quite long, very much like in today’s todies (Todidae) and its feet were syndactyl (that means two of the toes, toes 3 and 4, are fused together), like those of all known Coraciiformes showing that it was a member of that order.

The species is known from several specimens, some of which also still harbor their feathering, showing that this species had rather roundish wings and a rather long tail.
