Overview

Excerpt from The Permo-Carboniferous Red Beds of North America and Their Vertebrate Fauna With the exact age of the beds the author has not troubled himself in this publication; the solution of this vexed question must require distinct treatment and the best efforts of men far better qualified than he is at present to evaluate the evidence of invertebrate fossils. Suffice it to say that from the evidence furnished in detail in the body Of this paper he is convinced that the stage of evolution of the vertebrates, their stratigraphic position, and the accompanying invertebrates indicate that the beds are of Fermo Carboniferous age, and this conclusion is reached with a full knowledge that the evidence from fossil plants is in favor of the Permian age of the beds. Conflicting evidence of age from plant and animal fossils is no new thing in stratigraphy, and we must wait until a more complete knowledge can reconcile the different interpretations.
