Find history
Charles W. Gilmore (1874–1945) published the first scientific description of Alectrosaurus in 1933 using fossil remains from the Iren-Dabasu Formation in the northern Chinese autonomous region of Inner Mongolia . Since the bones of Alectrosaurus were found at the site together with the arm bones of another dinosaur, an incorrect reconstruction of the tyrannosaur with unusually long arms took place. The arm bones were later recognized as those of a representative of the Therizinosauroidea (Segnosauria).
