Steinmann and Ludwig Döderlein is a scientific textbook written in the late 19th century. It offers a concise, illustrated survey of fossil organisms and their stratigraphic value, emphasizing phylogenetic relationships where the fossil record permits and addressing student needs. Plants are largely set aside in favor of animal groups with robust preservation, with special depth on cephalopods and evolution-focused treatments of vertebrates—especially mammals, including North American material. Foundational topics such as fossil preservation, occurrence, and geologic time support the work’s extensive systematic coverage. The opening of this textbook presents a preface that defines scope and audience, explains the provisional exclusion of plants, and justifies a genetic (phylogenetic) approach for well-documented animal groups; it singles out cephalopods for unified treatment, notes that a parallel molluscan overhaul could not be completed, and stresses vertebrate phylogeny—particularly mammals—drawing on North American finds and advances in dentition analysis; it also thanks numerous collaborators and illustrators. The initial chapters then set out paleontology’s twin aims (biological and geological), describe why the fossil record is incomplete, and outline typical preservation modes for animals and plants (from mineral replacement to casts, steinkerns, and carbonization). They explain how stratigraphy, facies, and provinciality enable relative dating, highlight the value of widely distributed, rapidly evolving index fossils, and distinguish isomesic versus heteromesic comparisons. The section closes by presenting the conventional, relative geologic time framework (Azoic, Paleozoic, Mesozoic, Cenozoic) and their formations, with synchronized tables that correlate regional stage names while stressing their approximate, not absolute, equivalence.
