Taxonomy
Messelobunodon ceciliensis was named by Franzen and Krumbiegel (1980) [fragmentary skull of juvenil individual, in the Geiseltalmuseum of Martin-Luther-Universita, Halle-Wittenberg, Germany]. Its type specimen is Cl NO 305, Geiseltal, Germany, a skull (skull with upper dentition), and it is a 3D body fossil. Its type locality is Geiseltal, Cl IV, Grube "Cecilie", Trichter NE, which is in a Lutetian lacustrine horizon in Germany. It is the type species of Eurodexis.
It was recombined as Eurodexis ceciliensis by Sudre and Erfurt (1996), Erfurt and Sudre (1996), Theodor et al. (2007) and Luccisano et al. (2020).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. L. Franzen and G. Krumbiegel 1980 | One species of Messolobunodon, which differs from Type-specimen M. schaeferi FRANZEN 1980 by a distinct Hypocone at upper M1-2, and a corresponding Entoflex (Terminoloy from Coombs& Combs, 1977, p. 292, fig.1) at the broad lingual side of those teeth. | |
| J. Erfurt and J. Sudre 1996 | Bisher größte Art der Gattung. Außenhöcker der oberen Molat'en mit Centrocrista. Hypoconus am M' und M2 deutlich auf Postcingulum ausgebildet. Ectocingulum umfaßt Metaconus, und streicht am Paraconus aus. Untere Molaren mit Postentocristid, das im abgewinkelten Verlauf zum Hypoconulid gerichtet ist (vgl. Abb. 2 und Tafel 2, Fig. 6). Am P 4 existiert ein Metaconid. | |
| V. Luccisano et al. 2020 | (following Theodor et al. 2007). Small dichobunids with triangular, evenly sized upper molars, M3/ slightly smaller than M2/. M1/ and M2/ bear a hypocone but no mesostyle. P1s are separated by a mesial diastema from the canines and a distal diastema from P2s. All canines small, C and p/1 premolariform. Lower canine incisiform, closely appressed to incisors. Trigonid much higher than talonid; paraconid weakly separated from metaconid by a shallow notch. Talonid basin is lingually closed by a preentocristid. Postentocristid often connected to posthypocristid. A hypoconulid is situated on a short postcingulid. |
