    Isn’t it superfluous to say that it’s a Platysternid when it’s only one species?
    Cool study, though I wonder how often Platysternon walks on sand in the wild?

      In the modern context it says that a trackway was not made by another turtle. The tracks give you an indication that at least one individual is in the area even if that individual cannot be found. In the context of trace fossils it may allow identification of past areas of occurrence.

    Surprised to see how detailed those trackways come out; very nice.

      It has surprised us just how clearly even dry sand will take tracks. Particularly in our more controlled experiments with other species seeing detailed plastron imprints, tail drags and toe marks.
