I removed in the listing of subtaxa Mareda, Naraoiida, and Olenellida.
- Mareda Kobayashi, 1942 is not an order, but a genus, and on top of that, it is a jr. homonym of Mareda Walker, 1855 that was proposed for a genus of moths family Limacodidae. As new name has been proposed Suluderella Özdikmen, 2006 (Saukiidae). The Paleobiological Database posts as subtaxa all taxa that have not been assigned to other subtaxa, and combined with the suffix -da, it causes confusion.
- Although Naraoiida is used as a synonym for Nektaspida, the latter is much more commonly used, particularly in recent scientific literature, see: Budd, G. E. (1999). "A nektaspid arthropod from the Early Cambrian Sirius Passet fauna, with a description of retrodeformation based on functional morphology". Palaeontology 42: 99. doi:10.1111/1475-4983.00064, and Budd, G. E.; Jensen, S. (2000). "A critical reappraisal of the fossil record of the bilaterian phyla". Biological Reviews of the Cambridge Philosophical Society 75 (2): 253–95. doi:10.1111/j.1469-185X.1999.tb00046.x
- The communis opinio still seems to be that all trilobites primitively without facial sutures should be assigned to the suborder Olenellina, although cladistic considerations led Lieberman (2002) to dwell on the thought to raise the group consisting of the Olenelloidea, Judomioidea and Nevadioidea to the order Olenellina, and retaining the sutureless Fallotaspidoidea in the otherwise sutured Redlichiida. He did not propose it in his taxonomy however.
