The name "Goodland" is used only in north Texas from about Hood county northward. From Hood county southward the equivalent limestones are called the Edwards and Comanche Peak Formations. The difference between the Edwards and Goodland is that the Edwards contains an abundant fauna of rudists and large corals while the Goodland contains no rudists except maybe as rare isolated specimens and no large corals. Otherwise many of the other fossils are identical. |
