Abstract The Falls of the Ohio is a world-renowned geoheritage site of palaeontological and geological importance that also played key roles in the cultural and historical development of America. Studied by geologists for over two centuries, over 600 species of fossils are known from the site, hundreds of which were first described here. Beyond geology, the Falls of the Ohio can also be considered the origin and ending of the Lewis and Clark expedition, as well as an important location for naturalists and educators. A treasure of natural and human history and a National Natural Landmark, this spectacular 220 acre (89 ha) expanse of fossiliferous bedrock is worthy of ongoing study and protection.

ABSTRACT William Maclure, Father of North American Geology, partnered with Robert Owen in 1825 to establish an experimental socialistic community focusing on equitable reform in New Harmony, Indiana, USA. Artists, educators, and natural scientists recruited from Philadelphia arrived on a keel boat named Philanthropist in January 1826. Upon their arrival, Maclure established the New Harmony schools using a modified Pestalozzian educational approach under the guidance of Madame Fretageot. The New Harmony schools focused on practical education through direct observation of nature as well as a curriculum involving drawing, music, science, writing, and trade skills such as carpentry, engraving, and printing. Furthermore, the integration of arts and sciences with hands-on experiences led to a productive community of natural scientists who published significant works on the conchology, geology, ichthyology, and paleontology of North America. In the mid-nineteenth century, hand-drawn illustrations were reproduced through engravings, etchings, or lithography prior to the invention of the daguerreotype process in 1839, collodion wet plate process in 1851, and flexible celluloid film in 1888. In particular, the published works of David Dale Owen demonstrate the increasing importance of evolving reproduction techniques to paleontological illustration as well as the significance of hand-drawn artistic renderings. Interestingly, the modified Pestalozzian educational approach introduced by Maclure in New Harmony has several implications for the modern classroom. For instance, recent studies suggest that drawing improves spatial reasoning skills and increases comprehension of complex scientific principles. Likewise, engaging students in the drawing of fossils delivers a meaningful learning experience in the paleontology classroom.
