Models showing differences in total distance from the anterior hypostome tip to the anterior margin of the head shield for each specimen. Measurements [µm] were taken directly in Amira. a YKLP 11407. b YRCP 0011. c Hz-f-10-45. View from dorsal with semi-transparent head shield. Head models were built in Blender using Amira volume renderings as well as photographs of the specimens as a template. Length and number of the basal most antennular articles are assumed. Shape and length of the post-antennular head appendages of specimen Hz-f-10-45 resemble those of specimen YRCP 0011 due to the scarcity of appendicular details in the volume renderings of this specimen. an, antennulae; as, antennular scale; bn, basal most antennular articles; en, endopod; ex, exopod; he, head; hy, hypostome. Not designed to scale
