 Leeds had a rival, the collector Henry Keeping, who in 1899 tricked pit workers into selling dorsal fin rays by misinforming them that Leeds had lost interest in such finds.Keeping again sold these to the University of Cambridge where they were catalogued as specimen CAMSM J.46873.In September 1901, they were examined by the German palaeontologist Friedrich von Huene, who identified them as tail spikes, "Schwanzstacheln", of "Omosaurus", the second time "Leedsichthys" remains were mistaken for stegosaurian bones; Leeds himself was able to disabuse von Huene the same year.
