About Drinker:

In the late 19th century, Edward Drinker Cope and Othniel C. Marsh were mortal enemies, constantly trying to one-up one another on their paleontological digs. That's why it's ironic that the small, two-legged ornithopod Drinker (named after Cope) may be exactly the same animal as the small, two-legged ornithopod Othnielia (named after Marsh); the differences between these dinosaurs are so minimal that they may one day be collapsed into the same genus.
