The four other Eocene caviomorph-bearing localities from the same section (CTA-52, CTA-50, CTA-41, and CTA-53; Antoine et al, 2016) have been excluded because they only yielded fragments of rodent incisors, unidentifiable at a family level or below.

Following Antoine et al (2016, figure 3), all these localities are referred to the lower member of the Pozo Formation ("Pozo Sands"; Figure 1.2-3) and correspond to scattered inframetric channelized sandstone lenses (Antoine et al, 2016, figure 5.A-B). At CTA-51, CTA-27, CTA-29, and CTA-66, these sandstones are massive, gray to yellowish, and unconsolidated.…”

“…Recently, Antoine et al (2016) published a noteworthy paleontological and geological survey of the Cenozoic deposits along the Quebrada Cachiyacu near Contamana in Peruvian Amazonia. Of the 19 caviomorph-bearing localities identified by these authors in a single section, 10 are Eocene in age (middle Eocene-late middle Eocene; including CTA-27).…”

The Deseadan South American Land Mammal Age (late Early Oligocene -Late Oligocene) attests to a time of great diversification in the caviomorph rodent fossil record. Nevertheless, Deseadan rodent-bearing localities in Neotropical lowlands are few and poorly known. Here we describe the rodent assemblages from two Late Oligocene localities, near Contamana, Loreto, Peru. Seven taxa are new to science: Palaeosteiromys amazonensis gen. et sp. nov., Plesiosteiromys newelli gen. et sp. nov., Loretomys minutus gen. et sp. nov., Scleromys praecursor sp. nov, Ucayalimys crassidens gen. et sp. nov., Chambiramys sylvaticus gen. et sp. nov. and Chambiramys shipiborum gen. et sp. nov. These rodent faunas show that caviomorphs were relatively diverse in Peruvian Amazonia during the Late Oligocene, with the co-occurrence of at least three extant superfamilies: Erethizontoidea, Octodontoidea and Chinchilloidea. Additionally, they mark the earliest known
