Cartoon from Punch, September 13th 1890 showing Professor Othniel Marsh standing atop a triceratops skull, with some of his famous discoveries before him. Top left Pteranodon (Marsh 1870) the first pterosaur to be discovered outside Europe. Lowest the toothed bird Hesperornis regalis (Marsh 1871), right Brontops robustus (Marsh 1887) left Uintatherium - a species actually described by Joseph Leidy in 1872 and whose identification suffered from the developing 'bone wars' between Marsh and his palaeontological rival Edward Drinker Cope.
