Grundzüge der Paläontologie (Paläozoologie). 1. Abteilung: Invertebrata.

A concise yet richly illustrated survey of fossil invertebrates, this early‑20th‑century work brings the foundations of paleontology to life for modern listeners. The author frames the science around natural systematics, showing how morphology and evolutionary relationships guided classification long before molecular tools existed. Over 1,400 line drawings punctuate the text, giving a vivid picture of shells, spines and trilobite segments that once populated ancient seas. While the treatment remains brief, it captures the rapid advances of the era and the scholarly dialogue that reshaped the field.

The book deliberately focuses on the organisms themselves, treating fossils primarily as specimens rather than age markers for rock layers. It sketches the breadth of invertebrate diversity through careful naming and selective description, offering enough context for listeners to grasp the emerging phylogenetic ideas of the time. Although detailed family trees are omitted, the layout hints at the genetic ties that early paleontologists inferred. Listeners will come away with a clear sense of how the discipline evolved and why these ancient creatures remain central to understanding Earth’s deep past.
