       Chelosphargis was originally named as species of Protostega in‭ ‬1906‭ ‬by Oliver Perry Hay.‭ ‬However the description of Calcarichelys in‭ ‬1953‭ ‬led a later palaeontologist,‭ ‬Rainer Zangerl to conclude that P.‭ ‬advena should be reclassified as a distinct genus.‭ ‬Chelosphargis is regarded as being almost identical to Calcarichelys,‭ ‬a turtle with a series of large spines down the middle of its shell,‭ ‬with the only distinct difference between them being the formation of the keel in Chelosphargis.‭
