Fossil representation: Holotype is a partial post cranial skeleton of a subadult,‭ ‬though many more individuals have now been assigned to the genus.

       Drinker might sound like an odd name for a dinosaur,‭ ‬but this dinosaur is named‭ ‬after‭ ‬Edward Drinker Cope,‭ ‬a man who in the late nineteenth century‭ ‬who‭ ‬made many of the most important discoveries in American paleontological history during that time.‭ ‬Most of this is derived from Cope’s involvement in the‭ ‘‬Bone Wars‭’‬,‭ ‬a fierce rivalry between Cope and another naturalist named Othniel Charles Marsh.‭ ‬Marsh also had a dinosaur named after him called Othnielia,‭ ‬and later another called Othnielosaurus‭ (‬based heavily upon fossils previously assigned to Othnielia‭)‬,‭ ‬and in a quirk of history,‭ ‬Drinker,‭ ‬Othnielia and Othnielosaurus were very similar dinosaurs to one another.‭ ‬The‭ ‬type‭ ‬species name of Drinker,‭ ‬D.‭ ‬nisti is named after NIST,‭ ‬the National Institute of Standards and Technology.
       Subsequent discussions‭ ‬about Drinker have noted the broad foot of this dinosaur,‭ ‬which may have been an adaptation to living in a wetland environment,‭ ‬something that has been indicated by plant fossils of marsh vegetation,‭ ‬as well as teeth of lungfish.‭ ‬In addition to this some specimens of Drinker have been located in pods,‭ ‬which have been interpreted by Robert Bakker as possible burrowing behaviour by this dinosaur.‭ ‬While rare,‭ ‬burrowing in dinosaurs is known,‭ ‬with the most commonly cited example being the genus Oryctodromeus.
