Kimberellomorpha(Erwin 2011) [1](kimberellomorphs) are a group of animals from the Ediacaran period. Kimberella is the type genus.[2][3][4][1][5][6]
Classification
[edit]Kimberellomorphs are generally considered Bilaterians , and sometimes stem Mollusks.[2]
Diet
[edit]Kimberellomorphs grazed on microbial mats , possible stomachs and grazing marks( Kimberichnus) support this interception.[1][2][5]
Kimberichnus from the Triassic period
[edit]Kimberichnus have been reported from the Triassic period, although they belong to some other kind of grazing animal.
Morphology
[edit]Kimberellomorphs have an oval shaped shell covered in tubercles. They have an Radula-like structure on a retractable proboscis.They are bilaterally symmetrical. In Solza the head is not obvious, which may be because the animal is in its shell.[1][2][4][5]
Kimberellomorph -like proarticulans
[edit]Some Proarticulata resemble kimberellomorphs, but they are not considered Kimberellomorphs due to glide symmetry.[2]
Genera
[edit]After Budd and Jensen (2017)[3]
- Kimberella[1](speicies:K.quadrata,K.persii)
- Solza (may be a taphonomic variety of Kimberella)[2](speicies:S.margarita)
