[2] "Orce Man", a supposed archaic human fossil from the Early Pleistocene of Spain, was later determined to actually be the skull remains of a juvenile of this species.

[6]ST2 The species had slender limbs, the most slender among the "stenonines", including the metapodial bones, and is distinguished from other equines by a number of dental morphological features, including narrow and small crowns, and deep molar ectoflexid, though the dental morphology exhibits considerable variability in a number of characters.

[2] Equus altidens is known from remains found across Europe, Spanning from the Iberian Peninsula to Italy and Greece, northwards to Germany and Britain, and as far eastwards as Georgia in the Caucasus.

[6] Dental wear analysis that Equus altidens had an abraisive, largely grazing based diet,[2][6] though it may have seasonally engaged in mixed feeding.

[8] At the Fuente Nueva-3 site in Spain, during the late Early Pleistocene around 1.2 million years ago, cut marks found on bones indicate butchery of Equus altidens by archaic humans,[9] likely Homo antecessor.
