Etymology

The genus was named for the Itapecuru Formation of Brazil, the formation in which the remains of Itapecuruemys were situated.[1] The specific epithet is named after the Legal Amazon region, where it was discovered.[1]

Description

The carapace of Itapecuruemys amazoniensis is broad and low. The lateral margins converge posteriorly, with the widest point level with the fourth rib. Most of the carapace is unknown, consisting of one nuchal and several syprapygal plates, as well as seven neural plates and sixteen ribs. The first neural vertebra is similar to that of Kurmademys. The second to fifth neurals more closely resemble Foxemys. The nuchal plate is preserved only by a fragment of the anterior-most portion.[1] Scute preservation for Itapecuruemys is poor, with only the second and third vertebral scutes and second, third and fourth pleurals being recognizable.
