Taxonomic remark Taxonomic assignment (of Aspidella, hence by inference this family) has been controversial over time. From Retallack & Broz, 2020: Aspidella has been considered a pseudofossil, such as a gas escape structure, spall mark, or nodule (Häntzschel 1975; Boyce and Reynolds 2008). It has also been considered a microbial colony (Grazhdankin and Gerdes 2007), lichenised fungus (Retallack 2016a), cnidarian polyp (Menon et al. 2013), chiton (Billings 1872), and crustacean (Dawson 1897). Present IRMNG treatment follows these authors who place Aspidellidae in order Aspidellomorpha Retallack, 2016 which in that work is placed in "class" Vendobionta. [details]

Taxonomic remark Taxonomic assignment (of Aspidella, hence by inference this family) has been controversial over time. From Retallack & Broz, 2020: Aspidella has been considered a pseudofossil, such as a gas escape structure, spall mark, or nodule (Häntzschel 1975; Boyce and Reynolds 2008). It has also been considered a microbial colony (Grazhdankin and Gerdes 2007), lichenised fungus (Retallack 2016a), cnidarian polyp (Menon et al. 2013), chiton (Billings 1872), and crustacean (Dawson 1897).
