Quasisyndactylus is a primitive relative of modern-day kingfishers and bee eaters that lived about 50 million years ago in Europe. It was a small perching bird that could grow up to ca. 14 centimetres in length and had a typical bill for hunting small fish. It probably perched above the water's edge and plunge dived to get its prey. The fact that this species has been found in Europe during this time period, possibly indicates that the family of woodpeckers and bee eaters originate from this continent.
Quasisyndactylus was apparently a common species found around the Messel lake during the Eocene epoch. There have been found several complete fossils of Quasisyndactylus. Q longibrachus is the only member within its genus.
