Murell Park tracksite, SMU Loc. 234 (Arlington Mbr) (Cretaceous to of the United States)

Also known as Lake Grapevine, Murrell

Where: Denton County, Texas (33.0° N, 97.1° W: paleocoordinates 31.4° N, 61.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Conlinoceras tarrantense zone, Lewisville Formation (Woodbine Group), Early/Lower Cenomanian to Early/Lower Cenomanian (99.6 - 93.5 Ma)

• orig. lower part of Arlington Member, "not younger than early middle Cenomanian." Uppermost part of member contains a Conlinoceras tarrantense Zone ammonite fauna.

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; bioturbated, gray sandstone

• "low-lying coastal plain"
• "fine-grained, well-sorted light grey sandstone...heavily dinoturbated surface...irregular patches of wave ripple marks on the surface are evidence that at least some of the track area was under shallow water at some point. Invertebrate traces and syneretic mud cracks are also observed on the surface. Invertebrate traces are represented by Skolithos associated with algal mats, which are indicative of shoreline faces."

Size class: macrofossils

Preservation: trace

Collection methods: peel or thin section,
