Highlands tracksite (Jurassic to of South Africa)

Also known as Highlands ichnosite, Highlands 1239

Where: Free State, South Africa (28.4° S, 28.3° E: paleocoordinates 40.6° S, 3.3° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Lesotho Formation, Pliensbachian to Pliensbachian (190.8 - 174.1 Ma)

• lower part of formation

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; massive, fine sandstone

• "a palaeoenvironment with sheet floods, temporary streams, very rare dunes, and scattered ephemeral ponds or lakes into which some detrital sediments accumulated, and earliest lavas flowed."
• "the upper-bedding plane of a ~ 5-cm thick, massive, very fine to fine-grained sandstone layer, which is underlain by a horizontally laminated sandstone bed...The tracks, which are all on the same, essentially horizontal sandstone surface, are associated with horizontal, slightly meandering invertebrate trails and casts of desiccation cracks that range in width from a few mm to a few centimetres."

Size class: macrofossils

Preservation: trace

Collection methods: surface (in situ),
