Statistical analysis of the size of the eye and ommatidia of Voulteryon parvulus compared to those of other fossil polychelidans and arthropods: (A) relation between the size of carapace and diameter of the eye in polychelidan lobsters. (B) relation between the size of the eye and of ommatidia in polychelidan lobsters, with a comparison to the eyes of supposed phyllosoma larvae from Santana (Sant.) and a thylacocephalan (Dollocaris ingens) from La Voulte. The original measurements are in micrometers. Abbreviations: holo, holotype; para, paratype; hex, hexagonal ommatidia; Sant., phyllosoma from the Cretaceous Santana Formation sq, square ommatidia;. Original data for V. parvulus from the present study; for polychelidans, from Audo et al.5; for phyllosoma, from Tanaka et al.34; for Dollocaris ingens, from Vannier et al.10.
