TABLE 5. — Stylopodial bone lengths, midline carapace lengths (MiCL), and maximum carapace lengths (MaCL) for Proterochersis porebensis Szczygielski & Sulej, 2016.Incomplete humeri lengths estimated as 5.870655 distal depth (DD). Incomplete femora lengths estimated as 5.578671329 DD or extrapolated from proportions of complete femora (E). MiCL = humerus length / 0.28 or femur length / 0.32 (see text for discussion). MaCL = MiCL / 0.923889556 (based on average for complete carapaces ZPAL V. 39/48 and ZPAL V. 39/49). Estimated values indicated in italics. *, In juvenile specimens MiCL = MaCL, as evidenced by ZPAL V. 39/34 (28 cm); therefore, the formula used here is not representative for them. Moreover, the available sample is too limited to determine whether they followed the same linear size correspondence as larger specimens or if a more accurate model should be proposed. Therefore, the estimates presented here must be treated as rough approximations.
