Although well known as a local curiosity, this trackway has not previously been formally reported or described. It consists of five successive paces of what is interpreted as a medium-sized to large theropod dinosaur, and represents the largest known theropod trackway in the ‘Stormberg’ sequence in South Africa. The tracks are assigned to the ichnotaxon Grallator sp., and show similarities to North American tracks of comparable age originally described as Dilophosauripus. Until now no body fossils of a likely candidate trackmaker were known, but elsewhere in this volume a possible candidate is described by the second author.enArticle
