The Carboniferous Formations and Faunas of Colorado (Classic Reprint)

Excerpt from The Carboniferous Formations and Faunas of Colorado The paleontologic data for this work reside in a rather extensive collection from 200'localities, representing the available resources of the Geological Survey and the National Museum in the matter of Colorado Carboniferous fossils. In the paleonto logic discussion the purpose has been not so much to see what or how many species occurred within the limits of Colorado-as to ascertain their grouping into local and formational faunas, and to determine, if possible, by means of the invertebrate fossils, the relation -to one another of the strata forming the different more or less discon nected and isolated areas of Carboniferous outcrop. Aside from such correlative indications as the study of these collections has furnished, a fact of some interest, though by no means for the first time brought to notice, is the close relation which evidently existed in Carboniferous time between the Colorado Seas and those of the Mississippi Almost the entirety of the numerous fauna recognized in Colorado occurs also in the-coal fields of the Ohio and Mississippi valleys, and it has been found necessary to describe but very few species as new.
