Fallotaspidella is an extinct genus of redlichiid trilobites. It lived during the late Atdabanian stage,[1] which lasted from 530 to 524 million years ago during the early part of the Cambrian Period.
Distribution
[edit ]The type species, F. musatovi was collected from the Lower Cambrian of Siberia (later Atdabanian, southern Siberian fold belt, Altay-Sayan region, Lena Stage of the Batenevskiy Ridge).[2] [3]
Taxonomy
[edit ]Fallotaspidella is a derived member of the superfamily "Fallotaspidoidea". Fallotaspidella is closest to the trilobites with dorsal cephalic sutures, such as Bigotina and Lemdadella , making it pivotal in the understanding of the development of these sutures. Of all the other Fallotaspoids Archaeaspis is most related to Fallotaspidella.[3]
