Osteological associations with unique tooth development in manatees (Trichechidae, Sirenia): a detailed look at modern Trichechus and a review of the fossil record.
Anat. Rec. 295: 1504-1512. 4 figs. https://doi.org/10.1002/ar.22525
–ABSTRACT--Modern manatees have a unique type of tooth development, continually forming identical new molars in the posterior end of each quadrant of their mouths, and then progressively moving teeth anteriorly, only to reabsorb roots and spit out worn crowns. This process is not only developmentally complex, but requires space in the oral cavity that imposes its own limitations on other uses of that space. To gain a clearer understanding of the anatomical constraints on the evolution of this unique developmental process, we identified the specialized craniodental features in modern Trichechus that permit this specialization using visual observation and CT. Furthermore, to better understand the evolution of these traits, we review the fossil record of trichechids for these traits, including CT analysis of the skull of Miosiren kocki, a possible early member of the family from the Early Miocene of Belgium.

A new long-snouted species of the Miocene pontoporiid dolphin Brachydelphis and a review of the Mio-Pliocene marine mammal levels in the Sacaco Basin, Peru.
Jour. Vert. Paleo. 33(3): 709-721. 1 tab. 10 figs. + supplemental online data. May 2013.
–Notes the presence of "cf. Nanosiren sp." at the ELJ (El Jahuay) vertebrate fossil level (Late Miocene; dated as between 8.85 and 9.38 million years ago) (719, fig. 10). This record is based on Domning & Aguilera (2008: 496).
