“…The former is only known from lower dentitions, the latter only from upper dentitions. The synonymy of these genera has been discussed over several decades (see Walton & Porter 2008, for historical review). Unfortunately, the synonymy of Tillomys and Taxymys cannot be resolved at this time.…”

“…2004); some authors included them in Myomorpha (e.g. Matthew 1910; Walton and Porter 2008). Although Witenia and Atavocricetodon are Oligocene genera, they were studied here because Witenia represents the most recent pappocricetodontine form and Atavocricetodon characterizes eucricetodontines.…”

The origin of the Cricetidae and the relationships among earliest species from Central and East Asia are still disputed. The taxonomic status of some Eocene cricetid taxa is also doubtful. A parsimony analysis based on 65 cranial and dental characters and including 22 early Myomorpha was performed to elucidate these issues. As a result, the North American Elymys, known as the first Myodonta, belongs to dipodoid rodents, although it shares a suite of characters with the first cricetids. This implies that the split between dipodoids and muroids occurred in North America during the early middle Eocene, as previously supposed. The disputed Simimys and Nonomys could constitute an early dipodoid radiation. It appears that the earliest offshoot of the cricetid clade is the Asian genus Palasiomys. This taxon has a more advanced cricetid plan than contemporaneous dipodoids. The genus Raricricetodon no longer exists here because it is polyphyletic; the species are included in Palasiomys (P. minor, P. trapezius) and Pappocricetodon (P. zhongtiaensis). The genus Pappocricetodon displays a complete cricetid plan associated with both the loss of P 4 and the development of an anterocone on M 1 . The disputed genera Eocricetodon and Oxynocricetodon characterize the beginning of the Oligocene radiations of Eucricetodontinae throughout the Holarctic continents.

This contribution provides the raw files for the µCT-scan data and renderings of the three-dimensional digital models of two fossil teeth of a geomyin geomorph rodent (Caribeomys merzeraudi), discovered from lower Oligocene deposits of Puerto Rico, San Sebastian Formation (locality LACM Loc. 8060). These fossils were described, figured and discussed in the following publication: Marivaux et al. ( 2021), An unpredicted ancient colonization of the West Indies by North American rodents: dental evidence of a geomorph from the early Oligocene of Puerto Rico. Papers in Palaeontology.
