Labocania is a genus of carnivorous theropod, possibly tyrannosauroid, dinosaur from Baja California, Mexico, which lived 73 million years ago, in the Campanian stage of the late Cretaceous Period.
In the summer of 1970, the National Geographic Society and the Los Angeles County Museum of Natural History organised a joint paleontological expedition, led by geologist William J. Morris, to the Arroyo del Rosario in Baja California. While prospecting, volunteer Harley James Garbani discovered the skeleton of a theropod north of Punta Baja near Cerro Rayado. Garbani excavated the site in 1970 and 1971.
The type species, Labocania anomala, was described and named by Ralph Molnar in 1974. The generic name references the La Bocana Roja Formation, named after la Bocana Roja, "the red estuary". The specific name means "anomalous" in Latin, in reference to the distinctive build.
The holotype, LACM 20877, was found in a layer of the La Bocana Roja Formation, dating from the late Campanian, about 73 million years old. It consists of a very fragmentary skeleton with skull elements, including a right quadrate, a left frontal, a piece of the left maxilla, a fragment of the dentarium, a chevron, the upper parts of both ischia, the middle shaft of the right pubis, most of the second right metatarsal, a pedal phalanx and several loose teeth. The elements were not articulated, dispersed over a surface of about two square metres, and strongly weathered. The remains were mixed with the ribs of Hadrosauroidea.
