The "ivesheadiomorphs" are a group of fossilised structures known from Ediacaran localities in England and Newfoundland. They are considered to be taphomorphs (morphological variants attributable to preservation[1]) 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 before burial by sediment.[2]
Ivesheadiomorph structures were previously described as distinct organisms, namely Ivesheadia lobata ("pizza disk"), Blackbrookia oaksi, Shepshedia palmata[3] and Pseudovendia charnwoodensis.[4] However, all of these fossils have since been rejected as valid taxa.[2]
