Paraprefica
''Paraprefica'' is an extinct bird belonging to the Caprimulgiformes, from the middle Eocene (c. 48 million years ago). Its fossil remains have been found in the major paleontological site at Messel, Germany. ==Description==
This bird is known from fossil remains which include a skeleton and many well-preserved skulls, and is one of the best preserved Eocene birds. ''Paraprefica'', a medium-sized bird, has skull and legs somewhat resembling today's potoos, in the genus ''Nyctibius''. The head has a thin beak and a very wide mouth, while the wings are relatively large, though smaller than those of extant potoos.〔Mayr, 1999.〕〔Mayr, 2005.〕
