Project 4884: C. R. McCall. 2023. A large pelagic lobopodian from the Cambrian Pioche Shale of Nevada. Journal of Paleontology. First View:1-16.
Abstract
Lobopodians are an iconic and diverse group of animals from the Cambrian, which alongside radiodonts, present an important window into the evolution of arthropods, and the development of Paleozoic ecosystems. Of these, a rare few species outside of Radiodonta possess lateral swimming flaps. The recent discovery of Utahnax provided much needed insight into the evolution of swimming flaps, suggesting that the ventrolateral flaps of Kerygmachela evolved independently from other flap-bearing lobopodians and radiodonts. Here, a new pelagic lobopodian species is described, Mobulavermis adustus n. gen. n. sp., the first lobopodian to be reported from the Cambrian-age Pioche Shale of Nevada. Mobulavermis adustus was large, and possessed more ventrolateral flap pairs than any other known lobopodian or radiodont. It is found to be a close relative of both Kerygmachela and Utahnax, allowing the establishment of the new lobopodian family Kerygmachelidae n. fam. Additionally, an indeterminate euarthropod fossil from the Pioche Formation is described in brief, and the recently described Chengjiang species Parvibellus avatus, thought to have been related to the “gilled lobopodians”, is reinterpreted as a juvenile siberiid lobopodian.Read the article »
