In 1991, a single track of a tetradactyl tetrapod was found in a white/grey sandstone near Scarborough, North Yorkshire, England. The rock is of the Saltwick Formation and is Aalenian-Bajocian in age.

The track consists of three digits of approximate equal lengths (nr 10cm) and one shorter digit (nr 6cm). The digits splay at angles of 014 degrees, 022 degrees, and 083 degrees from the left digit. The spread is consistent with the left pes of a prosauropod dinosaur. As there is only one track, however, assigning any group to this track is highly controversial. It is impossible to state whether the animal was bipedal, or sprawled, or what its gait was. The track is into a grey mud and has been filled with the white/grey sand.

Although I returned to the site and completed a detailed lithological log of the cliff section, no more tracks came to light. As a result, no publication has been produced on this discovery, and the track remains in the collections of the Hunterian Museum awaiting a fuller description. The work was carried out with the help of the Clough Memorial Fund (Edinburgh Geological Society) in 1994.

For further information (although I can't think what else to say)

Please visit the Hunterian Museum. Scotland's first public museum opened in 1807 that is based on the collections of William Hunter, physician to the Queen in the late 1700's.
