The discovery of dinosaur bones in a bauxite mine at Cornet-Brusturi, near Oradea (Bihor County) was made accidentally by two miners in 1978 during ore exploitation. Almost at the same time, research in the already known Uppermost Cretaceous dinosaur-bearing deposits from the Hațeg Basin were restarted by Dan Grigorescu, after an interruption of more than 60 years, since Franz Nopcsa’s work in the region.
