Taxonomy
Podocnemis tatacoensis was named by Cadena and Vanegas (2023). Its type specimen is VPPLT-1727, a partial shell (nearly complete shell missing: left peripheral 1; the most anteromedial portion of nuchal; left costal 4; portions of left costals 2, 3, and 5; right costal 2, ), and it is a 3D body fossil. Its type locality is La Repartidora, which is in a Miocene terrestrial sandstone in the Victoria Formation of Colombia.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. A. Cadena and R. D. Vanegas 2023 | Podocnemis tatacoensis n. sp., differs from all other extant species of Podocnemis by having eight neurals, of which neural 8 interrupts the medial contact between costals 7 and the most anteromedial portion of costals 8. It shares with P. unifilis, P. vogli and P. erythrocephala three lateral musk ducts in each hyoplastron-peripherals contact. It shares with P. unifilis, P. sextuberculata and P. negrii keeled neurals. It shares with all extant Podocnemis spp. a nuchal bone being much wider than long. It shares with all extant and many fossil pelomedusoids (except P. pritchardi) a nearly rounded mesoplatra. It shares with all extant podocnemidids (Podocnemis spp., Erymnochelys madagascariensis and Peltocephalus dumerilianus) at least one musk foramen located at the most anterior tip of the sutural contact between hyoplastron and peripherals (axillary buttress region). |
