From: An embryological perspective on the early arthropod fossil record

Fig. 7

Reconstructed germband of the common ancestor of crown group Mandibulata, based on numerous extant taxa. The upper panel represents an early stage germband with the expression of select marker genes mapped onto it. The lower panel represents a late stage germband, annotated with the adult fate of the main embryonic features. The specific reconstruction includes three distinct tagmata – the head, which includes three post antennal segments; the anterior/trunk tagma (pereon/thorax-like) with limbed segments; and the posterior/abdominal tagma (pleon-like) with limbless segments
