The type species was first named and described by Friedrich von Huene in 1929 as Campylodon ameghinoi,[1] the genus name meaning 'bent tooth', from Greek καμπυλος, 'bent' or 'curved' (as of a bow) and ὀδών meaning 'tooth'. The specific name honours Florentino Ameghino. In 1961 H. Haubold and O. Kuhn noted that the name was pre-occupied by a fish and renamed the genus into Campylodoniscus, the diminutive.[2]

The fossil remains of Campylodoniscus were found in the Bajo Barreal Formation and consist of a single jaw bone, the maxilla, holding seven teeth.

Campylodoniscus dates to the Cenomanian (95 Ma). It is sometimes estimated as being around twenty meters in length.

Campylodoniscus is probably a member of the Titanosauria. Some researchers consider it a nomen dubium.
