Ivesheadiomorphs
The "ivesheadiomorphs" are a group of fossilised structures known from Ediacaran localities in England and Newfoundland. They are considered to be taphomorphs that represent the poorly preserved biological remains of various contemporary taxa such as ''Charnia'', ''Charniodiscus'', ''Bradgatia'', ''Primocandelabrum'', ''Pectinifrons'' and others, that were effaced by partial decay by micro-organisms following death on the seafloor prior to burial by sediment.
Ivesheadiomorph structures were previously described as distinct organisms, namely ''Ivesheadia lobata'' ("pizza disk"), ''Blackbrookia oaksi'', ''Shepshedia palmata'' and ''Pseudovendia charnwoodensis''. However, all of these fossils have since been rejected as valid taxa.〔
