Diagnosis
ReferenceDiagnosis
C. W. Hibbard 1937 (Eocastoroides lanei)Strongly hypsodont prismatic cheek teeth with the base
of the tooth open even in extremely old and heavily worn teeth. The dorsal surface of the lower incisor flat, passing along the lingual side of M2 and directly under M3 with the entire base of M3 resting upon the flat dorsal sur- face of the incisor. M2 and M3 with hypostriid and mesostriid deep and ex- tending to the base of the tooth. M2 with anterior and posterior transverse diameter equal; S pattern. M3 narrower posteriorly, S pattern indicated, though the posterior loop of enamel is separated entirely from the anterior loops. Fossettids are absent on cheek teeth at hand. Masseteric fossa deep and well developed. Largest of the known Pliocene beavers.
