Etymology: Chimaera: Named for the mythological creature composed of parts of multiple animals, referring to their odd mix of characteristics (See ETYFish); lignaria: Latin for of or belonging to wood, referring to Kevin J. Dagit, woodworker, carpenter and “supporter of research on chimaeroid fishes in his spare time” (Sharks: An Eponym Dictionary identifies Dagit [misspelled Dadit] as Didier’s son; he was, in f (See ETYFish).
Eponymy: Kevin J Dagit was, at the time of the description, the describer’s husband. [...] (Ref. 128868), visit book page.
