'''''Ribodon''''' is an extinct [[genus]] of [[Trichechidae|manatee]] that lived around [[South America]] ([[Ituzaingó Formation]], then described as Entrerriana Formation, [[Argentina]], [[Solimões Formation]], [[Brazil]] and [[Urumaco Formation]], [[Urumaco]], [[Venezuela]]) during the [[Tortonian]] ([[Mayoan]] to [[Huayquerian]] in the [[South American land mammal age]]s). The [[type species]] is ''R. limbatus''.<ref name="paleobio-db"/><br />
<br />
''Ribodon'' is considered the direct ancestor of the ''[[Trichechus]]'' genus to which all modern manatees belong and was the first manatee to exhibit supernumerary molars that were replaced throughout life, indicating a diet of abrasive plants.<ref>{{Cite journal|url=https://www.jstor.org/stable/1304394|jstor=1304394|title=Evolution of Manatees: A Speculative History|last1=Domning|first1=Daryl P.|journal=Journal of Paleontology|year=1982|volume=56|issue=3|pages=599–619}}</ref> ''Ribodon'' is hypothesized to have inhabited both coastal and inland freshwater regions; however, in which of the two it originated is unknown.<ref>{{cite journal |url=https://www.researchgate.net/publication/349236077 |doi=10.1038/s41598-021-82390-2|title=The evolutionary history of manatees told by their mitogenomes |year=2021 |last1=De Souza |first1=Érica Martinha Silva |last2=Freitas |first2=Lucas |last3=Da Silva Ramos |first3=Elisa Karen |last4=Selleghin-Veiga |first4=Giovanna |last5=Rachid-Ribeiro |first5=Michelle Carneiro |last6=Silva |first6=Felipe André |last7=Marmontel |first7=Miriam |last8=Dos Santos |first8=Fabrício Rodrigues |last9=Laudisoit |first9=Anne |last10=Verheyen |first10=Erik |last11=Domning |first11=Daryl P. |last12=Nery |first12=Mariana Freitas |journal=Scientific Reports |volume=11 |issue=1 |page=3564 |pmid=33574363 |pmc=7878490 |bibcode=2021NatSR..11.3564D }}</ref><br />
