CPT-1980 is the museum catalog number for an isolated, 9.83 centimeters (3.87 in), tooth belonging to an allosauroid theropod dinosaur currently housed at the Museo Fundación Conjunto Paleontológico de Teruel.[1] In 2009, the tooth was compared to another allosauroid tooth from Portugal that measured 12.7 centimetres (5.0 in). Analysis led to the conclusion that CPT-1980 is the largest theropod tooth ever discovered in Spain. The theropod most likely measured between 6 -15 meters long.

The tooth was first discovered by local near Riodeva, Teruel in the Villar del Arzobispo Formation, more specifically known as RD-39. The tooth has been dated to the Tithonian-Berriasian stages.[1]

The tooth is composed of a crown and is partially eroded.[1]
