Hortalotarsus (etymology uncertain; probably "tarsus of a young bird"?[1]) is a dubious genus of extinct sauropodomorph from Early Jurassic rocks of South Africa.[2][3]

Discovery and naming[]

The type species, Hortalotarsus skirtopodus was named by Harry Seeley in 1894, initially as a species of Thecodontosaurus.[4] According to Robert Broom (1911), "Originally most of the skeleton was in the rock, and it was regarded by the farmers as the skeleton of a Bushman, but it is said to have been destroyed through fear that a Bushman skeleton in the rock might tend to weaken the religious belief of the rising generation."[5] Seeley however, states that most of the skeleton was lost by a failed attempt to free it from the rock by using gunpowder.[4] Some partial leg bones were salvaged.

Hortalotarsus was subsequently regarded as either a synonym of Massospondylus[6] or a valid genus belonging to Anchisauridae.[7][8] Galton and Cluver (1976) as well as Galton and Upchurch (2004), however, designated this genus a nomen dubium.[9][10]
