Prof. WALTER G. JOYCE, Department of Geosciences, University of Fribourg has been kind enough to try to narrow down the species: "Of the four species that are known from the Lower Eocene of Wyoming, I can rule out one right away (Palatobaena gaffneyi), but the remaining three species (Chisternon undatum, Baena arenosa, and "Baena" affinis) are impossible to distinguish fresh from the egg because the shell has not yet formed. True, Chisternon undatum has been described from the Green River Formation, but I think there is no reason to exclude the other two species, especially since only one individual has ever been scientifically described from that formation. Thus, your turtle is probably only to be referred to as Baenidae indet."
