Info
Albertosaurus = ?Deinodon (Leidy, 1856) Albertosaurus > Albertosaurus incrassatus (Cope, 1876 vide Huene, 1932) >> Laelaps incrassatus (Cope, 1876) ?Deinodon horridus ((Leidy, 1856) ? Laelaps falculus (Cope, 1876) ?Lealaps hazeniasus (Cope, 1876) ?Dryptosaurus kenabekides (Hay, 1899) Albertosaurus > A.sarcophagus (Osborn, 1905) >> A. arctunguis (Parks, 1928)
Fragmentary skull found by J. B. Tyrrell in 1884 in the badlands of the Red Deer river, near the modern-day city of Drumheller (central Alberta). It found its way to the Geological Survey of Canada in Ottawa (it resides today in the Paleobiology Laboratories of the Canadian Museum of Nature, in the same city). It was studied by E. D. Cope who identified it as Laelaps incrassatus, an invalid generic name since Marsh had renamed this Dryptosaurus in 1877. At that time in Canada, there were no dinosaur specialists, so it wasn\\\'t until 1905 that the generic name Albertosaurus was created based on that skull and other fossils that had been found in the meantime.
