On a New Exogyra From the Del Rio Clay and Some Observations on the Evolution of Exogyra in the Texas Cretaceous (Classic Reprint)

Excerpt from On a New Exogyra From the Del Rio Clay and Some Observations on the Evolution of Exogyra in the Texas Cretaceous I do not propose to prove that the evolution of the Texan Exogyras was entirely continuous, because my material is still very incomplete; but I wish to open a road for some body else who may want to demonstrate in what manner Exogyra developed in Texas during the Cretaceous. It will probably be found that such an evolution existed and was at least partly parallel to the development of this genus in southern Europe and northern Africa; possibly in the later stages also in Asia. Thus the content of the following paper will be merely a sketch, but it may point out a way for a monographical description of the Cretaceous species of Exogyra in Texas.'
