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.
