In 2001, Ronan Allain concluded that no connection could be proven between "Piveteausaurus" and the referred other theropod material from Normandy. He also pointed out that the skull von Meyer had based "Streptospondylus altdorfensis" on was in fact a composite of bones from two species, since named "Steneosaurus edwardsi" Deslongchamps 1866 and "Metriorynchus superciliosum" Blainville 1853 (Steel 1973). A lectotype had never been chosen from one of the composite parts to give the name "Streptospondylus" priority over either one of these species. Allain used this situation to remove all the crocodilian material from the "Streptospondylus" type by designating the complete (postcranial) theropod material as the lectotype. As "Steneosaurus rostromajor" had been based on the composite skull, the epithet "rostromajor" now no longer had priority over "altdorfensis". This way in 2001 "Streptospondylus altdorfensis" became the valid name and type species of a theropod. "Laelaps gallicus" and "Megalosaurus cuvieri" are its objective junior synonyms.
