•A sandstone block containing the fossil was isolated from the rock and protected by a

•plaster jacket. Then, the mold was prepared under a binocular microscope and completely reinforced with cyanoacrylate. A computed tomography analysis was made so as to reject or confirm the presence of bones potentially included in the sandstone block. Standard petrographic thin-sections of shell bone samples were prepared for histological analysis. The shell surface pattern was analyzed using a JSM-5900 LV scanning electron microscope (SEM).

MGT-1185, which consists of an external partial mold of carapace that preserves the morphology of some scales: vertebrals 1–3 and the anterior part of vertebral 4; marginals 1–3; one pair of supernumerary anterior scutes; and medial portion of pleurals 1–3. It also preserves the morphology of some plates: the nuchal, peripherals 1–4 (partially), neurals 1–6, and costals 1–5. Holotype also includes two partial costal plates, one neural plate, and several shell bone fragments. Positive and negative casts of the holotype are deposited at Facultad de Ciencias, Uruguay, as FC-DPV-2761.
