Catherine Forster, in a 1984 paper on the ecology of Tenontosaurus, used this as evidence to suggest that Tenontosaurus populations did not arrive in the Bighorn Basin area until the time of the late Little Sheep Mudstone Member.
Catherine Forster je u jednom članku (1984.) o staništu Tenontosaurusa iskoristila to kao dokaz da bi predložila da se populacija Tenontosaurusa nije pojavila na području Bighorn Basina sve do kasnog perioda u kojem je nastao član Little Sheep Mudstone.
