Note: I spell-checked these names and corrected them here and in the text of the various pages on which they appear.  One name did not appear on the Internet: Codospermum (p.081.)  Two other names used here appear to pertain to insects (Neuropteroid, p. 065) or lizards (cornutum, p. 077.) I cannot vouch for the accuracy of my grandfather's specific fossil identifications.  A great many of the names mentioned here are contained in the Mazon Creek Fossil Database of the Illinois State Museum.  When I visited the museum some years ago, I met Mr. Brian Bisbee, who was at the time using a flatbed optical scanner to make images of the fossils in that collection, all of which were donated to the museum in 1938 by my grandfather.  Some of the exact same specimens whose photographs are herein contained (that my grandfather made before his death in 1964) are represented in that database.
