It was recombined as Plesiochelys jaccardi by Rütimeyer (1873) and Bräm (1965); it was synonymized subjectively with Plesiochelys etalloni by Gaffney (1975); it was recombined as Craspedochelys jaccardi by Antunes et al. (1988), Lapparent de Broin et al. (1996), Anquetin et al. (2014) and Anquetin et al. (2017).

---|---|---|
J. Anquetin et al. 2017 | Craspedochelys jaccardi differs from all other Craspedochelys by having a more rounded carapace with its greatest width at the level of peripheral VII, a higher length/width ratio of the costal bones (4.8 or more, as opposed to around 4.3 for costal IV). In addition, Craspedochelys jaccardi differs from Craspedochelys picteti by being smaller in size (carapace length 420 mm) and by having an evenly rounded anterior carapacial rim, a contact between costal VIII and peripheral XI present, a wider than long pygal bone, and wider than long hyoplastra and differs from Craspedochelys passmorei by having a shallower nuchal notch, epiplastra that reach the lateral margin of the anterior plastral lobe, and a shorter posterior plastral lobe. |
