Chelonoidis gallardoi
Taxonomy
Testudo gallardoi was named by Rovereto (1914). Its type specimen is MACN 5206, a partial shell (partial shell of an adult individual), and it is a 3D body fossil. Its type locality is Santa Maria Valley Andalhuala Fm, which is in a Montehermosan/Chapadmalalan terrestrial horizon in the Andalhuala Formation of Argentina.
It was recombined as Chelonoidis gallardoi by Auffenberg (1974), de Broin and de la Fuente (1993), de la Fuente (1997), de la Fuente et al. (2014) and de la Fuente et al. (2018).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. S. de la Fuente et al. 2018 | Member of Testudinidae based on the following characters: presence of neural differentiation; coincidence of costo-peripheral sutures with pleuro-marginal sulci; fusion of twelfth marginal scutes; presence of a well-developed epiplastral lip. It is further characterized by a high, long and convex shell with neural and costal gibbosities. It differs from Ch. australis by the presence of gibbosities on both neural and costal bones, by the estimated length/wide ratio of the carapace, the presence of a deep anal notch, and the relative proportions of anterior and posterior plastral lobes. It differs from the extant Ch. nigra complex by a plastron proportionally not reduced with anterior and posterior plastral lobe relatively wide and by elongated gular and anal scutes. |
