Drinker nisti

During the latter part of the 19th century Edward Drinker Cope and Othniel Charles Marsh were embroiled in a bitter war of bones, catchily dubbed "the bone wars", and stopped at nothing to one-up each other by fair means or foul. They spied, sabbotaged and openly slandered each other at every given opportunity so it's a bit ironic that Drinker — a primitive ornithopod named in honor of the former, may be the same as Othnielosaurus (based on remains previously known as Othnielia) — a primitive ornithopod named to honor the latter.

Drinker was a small agile biped with unusually broad feet and long, wide-spread toes which may have evolved to negotiate a swampy habitat within Wyoming's Late Jurassic Morrison Formation. Bob Bakker has reported finding the remains of over thirty individuals in what might have been a burrow, though, of course, it could have just been a big hole.
Etymology
Drinker is named in honor of American paleontologist Edward Drinker Cope.
The species epithet, nisti, refers to the National Institute of Standards and Technology who funded digs at Como Bluff in the early 1990's.
Discovery
The remains of Drinker were discovered at the Main Breakfast Bench Quarry (aka "Big Nose") in the upper Morrison Formation, Como Bluff, Albany County, Wyoming, by James Siegwarth and James Filla in 1990 by James Siegwarth and James Filla in 1990, alongside fossilized lungfish teeth and marsh vegetation.
The holotype (CPS 106) includes partial jaws, arm and leg fragments.
