The Mastadon
"Exhuming the First American Mastadon," a project followed closely by Thomas Jefferson, as it provided evidence to refute de Buffon, who had theorized that the American environment was "deficient" and produced animals and plants inferior in size and virility to those of Europe. Painting by Charles Wilson Peale, 1806. Public domain.
