Anomalocarididae [1] (occasionally mis-spelt Anomalocaridae [2]) is an extinct family of Cambrian radiodonts, a group of stem-group arthropods. [3] [4]
Around 1990s and early 2010s, Anomalocarididae included all radiodont species, hence the previous equivalent of the common name "anomalocaridid" to the whole Radiodonta. [5] This is no longer the case after the revision done by Vinther et al. 2014, [3] as Anomalocarididae restricted to only Anomalocaris and, if any, a few of closely related genera since then. Wu et al. 2021 accepted only Anomalocaris (excluding "A." saron, "A." kunmingensis and "A." briggsi) and Lenisicaris as the member of Anomalocarididae, [4] while Paranomalocaris is questionably included by some studies as well. [6] [7] [8] Since then, other species labeled under the Anomalocaris genus, like ''A.'' saron have been reassigned to their own genus (like in the case of ''A.'' saron being redescribed as Innovatiocaris). [9]
Anomalocarididae distinguished from the similar family Amplectobeluidae (e.g. Amplectobelua, Lyrarapax) by the presence of triradial oral cone [10] and non-hypertrophied first distal endite. [4] Compared to Hurdiidae and Tamisiocarididae, this two radiodont families shared a lot of characters (i.e. alternated endite length; [11] streamlined body; [12] small head with ovoid sclerites; [13] [14] well-developed swimming flaps; [12] [13] [15] caudal furcae; [12] raptorial predatory lifestyle [16] [14] [11]) and forming a clade in multiple phylogenetic analysis.
