Paracricetodon
Taxonomy
Paracricetodon was named by Young (1925) [Eine zweite, etwas grössere Art wird möglicherweise durch zwei linke Unterkiefer, an welchen die hinter M folgende Partie weggebrochen ist, repräsentiert. Sie stammen von der nämlichen Lokalität in Ping-Fang-Hsien wie die Kiefer der vorigen Art. Wegen der Beschädigung des M1 lässt es sich nicht eintscheiden, ob diese Kiefer zu Paracricetulus oder zu Cricetulus selbst gehören, doch dürfte das erstere wahrscheinlicher sein, weil die "Vorerknospe" ebenfalls nur sehr klein gewesen sein kann. ]. It is not extant. Its type is Cricetodon spectabilis.
It was assigned to Cricetidae by McKenna and Bell (1997); and to Paracricetodontinae by Mein and Freudenthal (1971), de Bruijn et al. (2003) and Maridet and Ni (2013).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. de Bruijn et al. 2003 | Lower cheek teeth: Anteroconid of m1 weak and in many specimens developed as a low cingulum only. Metalophulid 1 usually missing in the m1, but present in the m2 and m3 (as in Pappocricetodon TONG, 1992 and Ulaancricetodon DAXNER-HÖCK, 2000). Endolophid complete and posterior arm of the protoconid strong in all molars. A free-ending posterior arm of the hypoconid is present in the m1 and m2 of all species and may be indicated in the m3 of some. The m3 is about as long as the m1, or longer.
Upper cheek teeth: Anterocone of the M1 rather strong and blade-shaped. The anterior arms of the protocone and hypocone are well developed in the M1 and M2 of all species, but absent in the M3 of some. The ectoloph sinuous as in many Miocene cricetid species from western Asia. |
