 This estimate has been corroborated by Rhaetian index fossils such as conchostracans and geomorphological data.Additional material attributed to "Terrestrisuchus" has been discovered in other Late Triassic fissure deposits in South Wales and Bristol, including the Ruthin Quarry in Wales and the Tytherington and Cromhall quarries near Bristol, as well as a possible specimen from Durdham Down.The fossils of "Terrestrisuchus" were originally housed at University College, London before being transferred to the Natural History Museum in London where they are currently stored.
