First edition. "Rare. One of the most important books in the early history of geology. This is the author's best known and most controversial work. Moro was interested in the fossils he found in the mountains and how they came to be there. In the 'De Crostacei e degli altri Marini Corpi' Moro speculates on the organic nature of fossils. He affirmed the theory that mountains and most islands were formed by volcanoes and thought that stratified rock was igneous in origin. His most original thoughts in this area consisted of the idea that two kinds of mountains existed, Primitive and Secondary, each of different age and composition. This theory, elaborated on by others, later became the foundation for studies in historical geology"(C. Schuh, Biobliography of minerology). "Moro was very impressed by the new volcanic islands that rose from the bay in Santorini in 1707. He was particularly struck by accounts that described how shells had been brought up from the bottom of the sea floor by the force of the eruption. It occured to Moro that perhaps this was the source of all fossil bearing beds" (W.B. Ashworth, Volcanoes, Basalt, and discovery of geological time p. 16). The title vignette shows a volcanic island, newly erupted and brimming with seashells. The English translation of the title is as follows: On shells and other marine bodies that are found on mountains.
