Comparison of embryonic gene expression patterns in representative developmental stages of Novocrania anomala, Terebratalia transversa and Phoronopsis harmeri. Schematic representation of the expression patterns of endomesodermal, anterior and posterior markers during gastrulation, axial elongation and larva formation of two members of Brachiopoda (N. anomala and T. transversa) and one member of Phoronida (Ph. harmeri). The asterisk is indicating the anterior domain. abl, anterior blastoporal lip; an, anus; bp, blastopore; mo, mouth; pbl, posterior blastoporal lip; vp, vegetal plate
