The page contains photos of lithographs commissioned by Othniel Charles Marsh (Professor of Paleontology at Yale University). On many of the scans, you will see the following notation: “F. Berger, del” on the lower left, and “E. Crisand, lith. New Haven” on the lower right. This indicates that the artist (delineator) working for Marsh was Frederick Berger. Emil Crisand worked as the lithographer for the printers in New Haven and prepared the images for printing, transferring the original drawing to the lithographic stone. When you see a fraction after Marsh’s name, it indicates the scale of the drawing, e.g. 1/2 indicates that the scale of the drawing is half the size of the original fossil.
These lithographic prints were donated to the Peoria Academy of Science April 14, 1937 by Ms. Gertrude A. Pauli (then a teacher at Whitier School in Peoria, Illinois). These lithographs are presently housed at the Peoria Riverfront Museum.
