Gives rise to the paired appendages in jawed vertebrates. a persistent somatopleure through the redistribution and expansion of the lateral plate mesoderm is a synapomorphy for gnathostomes and a critical step in generating a novel developmental module with dramatic evolutionary potentia (Tulenko et al. 2012) http://burkelab.research.wesleyan.edu/current-projects/lamprey/
