Mammalia - Artiodactyla - Palaeomerycidae
It was recombined as Blastomeryx sinclairi by Matthew (1924); it was synonymized subjectively with Cranioceras unicornis by Frick (1937) and Webb (1969); it was recombined as Rakomeryx sinclairi by Skinner et al. (1977), Janis and Manning (1998), Prothero and Liter (2007) and Prothero and Liter (2008).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|W. D. Matthew 1918||Size of D. whitfordi and very like it in construction but distinguished by higher crowned and less rugose molars with no trace of paheomeryx fold, metaconid of p4 smaller, less extended anteriorly, heel of ms with its inner cusp wholly or almost wholly behind the posterior wing of the hypoconid crescent.|
|D. R. Prothero and M. R. Liter 2008||Horns with less pronounced basal flange, anteriorly
directed, with bases strongly flattened anteroposteriorly, attenuated at tips; shafts strongly bowed laterally, forming concave half-moon shape when viewed from front. Orbits shifted posteriorly over anterior M3. Premolars more reduced than in Dromomeryx, but p4 may lack closure of anterior fossette. Metastylids on upper molars, and large metacone on
P4. Limb proportions like that of Drepanomeryx (after Janis and Man- ning, 1998, p. 483).
