Lepidocaris rhyniensis† Scourfield, 1926 is the earliest branchiopod-like fossil known from continental freshwaters in the Silurian and Devonian (Scourfield, 1926, Scourfield, 1940) but several authors have justifiably doubted whether these animals are in fact true branchiopods (Kotov, 2013, Sun and Yang, 2006, Wolfe and Hegna, 2013 ...High morphological plasticity in populations of brine shrimp subjected to different environmental conditions, mainly salinity, hindered for centuries the identification of the taxonomic entities encompassed within Artemia. In addition, the mismatch between molecular and morphological evolution rates complicates the characterization of evolutionary lineages, generating taxonomic problems.
