- Title
- Sammlung von Merckwürdigkeiten der Natur und Alterthümern des Erdbodens, v. 2
- Description
- Another volume of Knorr and Walch’s Collection of Remarkable Natural Objects (Sammlung von Merckwurdigkeiten der Natur, 1755-1775) is shown here, with a focus on a class of mollusks called ammonites. These extinct animals are most closely related to the extant nautilus, but differ in their ridged shells, which are shown here in great detail. Persuasive arguments were made at the time of this publication that the ammonites were not truly extinct, but merely waiting to be discovered in some far-off corner of the globe. By the 19th century, the consensus view was that ammonites were in fact extinct, and that the Secondary units in which they were found represented a distinctive time in Earth’s history. Ammonites were used by savants such as Giovanni Brocchi and Alexandre Bronginart to distinguish the older Secondary units (ammonites present) from the younger Tertiary units (ammonites absent), and they continue to be used in this manner by modern geologists.
