As studied by Scott, Matthew, and Merriam, they are in a high degree polyphyletic, including five or six distinct lines, as follows: The typical dogs, descendants of Cynodictis of the Oligocene, are represented by Tephrocyon and lead in the direction of Canis. The cyons or dhole-like dogs are successors to the Temnocyon and Daphwniis of the Oligocene with trenchant-heeled grinding teeth, and are represented by Cyan and Icticyon. The giant or bear-like dogs are represented by Amphicyon. The mustelid family is represented by a species of marten, by a primitive otter, as above noted, while the felids of Colorado are represented only by specimens doubtfully referred to the European Pseudcelurus. It is noteworthy that none of the machae- rodonts have been discovered at this stage, although they are abundant both in older and in more recent Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original O
