“Further, the closely related Nemertodermatida provide a connecting link to more conventional bilaterian designs.”
“As pointed out by a number of authors, the evolution of bilaterian body plans must postdate the cladogenetic separation of lineages leading to these animal phyla.”
“Another fossil, Vernanimalcula, has been interpreted as a coelomate bilaterian, but may simply be an infilled bubble.”
“It is not homologous with the bilaterality of body plans characteristic of anthozoan groups.”
“These organs retain their normal bilaterality, but the body is, as a rule, inequilateral.”
“The lesions in these diseases, however, can be distinguished from traditional CHRPEs in their characteristic pisciform shape, bilaterality, and multiplicity of lesions.”
