One specimen has been recovered from Quarry 9 of Como Bluff in Wyoming and another specimen was later reported from Dinosaur National Monument.[1] The Como Bluff specimen was an ilium only a few millimeters long.[1] Indeterminate specimens are known from Morocco.[2]
E. hechti's live weight would have only been a few grams.[1]
