Phylogeny of the Echini, With a Revision of Palaeozoic Species

"Phylogeny of the Echini, With a Revision of Palaeozoic Species" is a comprehensive study by Robert Tracy Jackson, originally published in 1912. This meticulously researched volume delves into the evolutionary history and classification of echinoids, commonly known as sea urchins. Jackson provides a detailed analysis of their phylogeny, tracing their development through geological time, with a specific focus on Paleozoic species.

This work offers valuable insights into the morphology, taxonomy, and evolutionary relationships of these fascinating marine invertebrates. It remains a significant contribution to the field of paleontology and invertebrate zoology, appealing to researchers, students, and anyone interested in the history of life on Earth.
