Trichechus manatus Linnaeus, 1758 View in CoL ( Figures 4 View FIGURE 4 , 5 View FIGURE 5 )

SHSU 1-027. Left edentulous dentary ramus with intact but abraded symphyseal region, labial alveolar surfaces, and posterior margin of the bone intact ( Figure 4 View FIGURE 4 ). The angular process is missing, as is the lingual portion of the alveolar region. Maximum preserved length is 16.5 cm; depth of the dentary at approximate midpoint of the anteroposterior length is 4.9 cm; depth from the top of the coronoid process to the (broken) base of what would be the angular process is 10.4 cm. From the Joe Liggio collection.

SHSU 1-231. Right anterior edentulous maxilla fragment, with a resorbed anterior alveolar region; two complete sets of molar alveoli and part of a third are preserved ( Figure 5 View FIGURE 5 ). Total preserved length is 8.4 cm. From the Brian Babin collection.

The preserved anatomy of SHSU 1-027 allows confident referral to Trichechus manatus , but the portions of the bone that would allow confident referral to T. m. bakerorum, the symphyseal and angular regions of the dentary, are abraded and absent, respectively.
