The present 3D Dataset contains the 3D models analyzed in Bianucci et al. 2023, A heavyweight early whale pushes the boundaries of vertebrate morphology, Nature. These include bones of the holotype of new species Perucetus colossus (MUSM 3248), as well as the articulated skeleton of Cynthiacetus peruvianus (holotype, MNHN.F.PRU10). The latter was used to estimate the total skeleton volume of P. colossus.

This contribution contains the three-dimensional digital models of a part of the dental fossil material (the large specimens) of caviomorph rodents, discovered in late middle Miocene detrital deposits of the TAR-31 locality in Peruvian Amazonia (San Martín, Peru). These fossils were described, figured and discussed in the following publication: Boivin, Marivaux et al. (2021), Late middle Miocene caviomorph rodents from Tarapoto, Peruvian Amazonia. PLoS ONE 16(11): e0258455. https://doi.org/10.1371/journal.pone.0258455
