Esthonyx spatularius Cope 1880 tillodont USNM nos. 511098 (L maxilla with M1-3), 533542 (associated teeth including L and RI2 or I3, RP3, LM2), 533591 (associated teeth including RI2, RP2?, RM2, damaged RM1 or M2), 538365 (RM1 trigonid, dentary fragments, and associated postcrania including damaged distal L tibia, astragalus and calcaneus, vertebrae), 539478 (damaged RMx), 541962** (LP4), 541963** (RM1, and RM3). Several of these specimens were found in different field seasons, but, based on location and stage of wear, probably represent the same individuals: USNM 511098, 533591, 538365, and 541962 are believed to represent one individual, and USNM 533542 and 541963 probably come from one individual.
