HLV-3, Habay-la-Vieille III (Triassic of Belgium)

Where: Gaume, Belgium (49.7° N, 5.6° E: paleocoordinates 36.3° N, 7.6° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Grès de Mortinsart Formation, Rhaetian (208.5 - 201.3 Ma)

• The complete stratigraphic log (as observed in 1996) is given in Godefroit (1999)

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; unlithified, pebbly, gray, green, argillaceous sandstone

• lithofacies at the entire section represent subtidal and littoral desposits
• the specific lithology of the bonebed is ambiguous in Godefroit (1999), but it lies within layers of gray to green clayey sands.

•Delsate 1995/6: 10 cm of fine green-gray sandstone with pebbles, base markeed by 2-3 cm deep pockets of erosion.

Size class: mesofossils
