Parapsicephalus (meaning "beside arch head") is a genus of " rhamphorhynchoid" (long-tailed) pterosaurs from the early Toarcian-age Lower Jurassic Alum Shale of Whitby, Yorkshire, England. It is known from a single partial skull lacking the snout, but including a detailed endocast of the brain.
It was collected in the 1880s by Reverend D.W. Purdon, who is honored in the specific name, and first described by Edwin Tulley Newton, who named it as a species of Scaphognathus, S. purdoni. It was recognized as a distinct genus only decades later in 1919 by Gustav von Arthaber, although in 2003 it was synonymized by David Unwin with Dorygnathus, repeated in a recent popular publication. It has been considered to be a rhamphorhynchid, of medium size (estimated wingspan of ~1 m ~[3.3 ft]), although a more recent estimation suggests it may have had a wingspan of over 2m,
