註釋In 1941 author MacNeal undertook to explore the western edge of outcrop of the Woodbine, which runs northeast to southwest through the eastern central part of Denton County, Texas. Here the Dexter sand member, a near-shore, largely non-marine deposit, was laid down before the transgressing Late Cretaceous sea had pushed the shore line to the northeastward to lay down the higher marine Lewisville beds. Not far within the western margin of the Woodbine belt, in the vicinity of the county seat, Denton, MacNeal found plant-bearing beds in four localities, & collected fossiliferous surface material in two other localities. He also found limited material in two localities outside Denton County, although no extended exploration was made. 36 plates.
