Taxonomy
Chelonoidis gersoni was named by Viñola-López and Almonte (2022). Its type specimen is MNHNSD FOS 23.001, a partial shell (Partial shell (MNHNSD FOS 23.001) of a female that includes the plastron (most of the epiplastron, entoplastron, hypoplastron, xiphiplastron, ), and it is a 3D body fossil. Its type locality is Cueva del Mono, which is in a Pleistocene terrestrial horizon in the Dominican Republic.

Diagnosis
ReferenceDiagnosis
L. W. Viñola-López and J. N. Almonte 2022Medium-size tortoise (greater length of the plastron: 28.12 cm) of the Greater Antilles Chelonoidis group (C. cubensis, C. marcanoi) based on the presence of
thin shell, prominent bony ridges in costal sulci, and strong epiplastral shelf that separates gular from the internal floor of the lobe. It can be distinguished from other species in the group based on the presence of pronounced gular projection with triangular lobes (sub rectangular in C. cubensis and C. marcanoi); oval entoplastron (sub triangular in C. cubenisis) with low brow, wide and low middle keel and shallow lateral fossae. Humerus with shallow muscle scar for M. latissimus dorsi (prominent in C. cubensis) and medial process at the same level of the humeral head (medial process higher than humeral head in other species of the genus).
