This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Quinotaur (Frankish)
The Quinotaur (Latin: Quinotaurus) is a mythical sea creature mentioned in the 7th century Frankish Chronicle of Fredegar. It was held to have fathered Meroveus by attacking the wife of the Frankish king Chlodio and thus, to have sired the line of Merovingian kings.
The "bull with five horns" was likened by Pseudo-Fredegar- interpolating Gregory of Tours who authored an earlier record of the legend- to both Neptune and the Minotaur, as it was both seaborne and taurine. It is not known whether one or both traits are original to the legend or if their combination is an accretion by one or both of the Christian authors.
