Epichirostenotes is known from an incomplete skeleton found in 1923 at the Horseshoe Canyon Formation, in strata dated to about 72 million years ago.1 It was first named by Robert M. Sullivan, Steven E. Jasinski and Mark P.A. van Tomme in 2011 and the type species is Epichirostenotes curriei. Its holotype, ROM 43250, had been assigned to Chirostenotes pergracilis by Hans-Dieter Sues in 1997.1
