• Palaeotherium is an evolutionarily derived member of its family with tridactyl (or three-toed) forelimbs and hindlimbs, small post-canine diastemata (gaps between teeth), and premolars that are usually developed into molar-like forms.
• marsupium, yet these are generally true of Herpetotherium) that he felt were especially comparable to Didelphis, such as "(1) the strong canine, (2) weak anterior premolar, (3) dominance of the protocone in the premolars, (4) fourth tooth of the series molariform, (5) position of mental foramen under this tooth, (6) identical form of the molars, (7) groove on the jaw suggesting an inflected angle," yet he pointed out several differences, such as "(1) absence of diastemata around the anterior premolar, (2) trend of the mental foramen forward instead of backward, (3) the inflected angle, seeming to begin beneath the molars" (p.
• It has longer postcanine diastemata (gaps between teeth) compared to Palaeotherium and brachyodont (low-crowned) dentition that evolutionarily progressed towards hypsodonty (high-crowned) in response to climatic trends.
• The postcanine teeth are autapomorphic for the genus in being arranged in three pairs of closely placed teeth separated by longer diastemata.
• As the type genus of the Palaeotheriidae, one of two families within the Equoidea, it shares common traits such as orbits that are wide in its back plus located in the skull's midlength, long nasal bones, selenodont form molars, and the presence of diastemata between the canine and other teeth between it.
