Contrary to a 1927 report by pterosaur researcher [[Ferdinand Broili]], ''Rhamphorhynchus'' lacked any bony or soft tissue crest, as seen in several species of contemporary small pterodactyloid pterosaurs. Broili claimed to have found a two-millimeter-tall crest made of thin bone that ran much of the skull's length in one ''Rhamphorhynchus'' specimen, evidenced by an impression in the surrounding rock and a few small fragments of the crest itself.<ref name="broili1927">{{Cite journal | last1 = Broili | first1 = F. | year = 1927 | title = Ein Exemplar von ''Rhamphorhynchus'' mit Resten von Schwimmhaut | journal = Sitzungs-Berichte der Bayerischen Akademie der Wissenschaften Mathematisch Naturwissenschaftlichen Abteilung | volume = 1927 | pages = 29–48 }}</ref> However, subsequent examination of this specimen by Wellnhofer in 1975 and Bennett in 2002 using both visible and ultraviolet light found no trace of a crest; both concluded that Broili was mistaken.
