...T. Alexander Dececchi; Guy M. Narbonne; Carolyn Greentree; Marc Laflamme The Rangeomorpha are the oldest, most diverse, and most disparate clade of Ediacaran macrofossils. Easily identifiable by their self-similar branching pattern, they occupied epibenthic niche space ranging from the lowest...

... in the assemblage is the Rangeomorpha, a frondose clade characterized by self-similar, repeating branching architecture known worldwide from rocks of Ediacaran age. Variations in branching characters and gross morphology have historically been used to divide this group, but there has been little consistency...

... 20 ingroup taxa with previously asserted affinities to the Arboreomorpha, Erniettomorpha, and Rangeomorpha. Using a newly derived morphological character matrix that incorporates multiple axes of potential phylogenetically informative data, including architectural, developmental, and structural...

... biotas of Avalonia—particularly the fractal-branching frondose Rangeomorpha— have been traditionally interpreted as living erect within the water column during life. However, due to the scarcity of documented physical sedimentological proxies associated with fossiliferous beds, Ediacaran paleocurrents...

... a phylogenetic hypothesis describing the interrelationships of the Ediacaran Rangeomorpha in “Phylogenetic relationships among the Rangeomorpha: the importance of outgroup selection and implications for their diversification”. Their work tests previously proposed groupings within the Rangeomorpha in addition...

...Patricia Vickers-Rich; Andrey Yu Ivantsov; Peter W. Trusler; Guy M. Narbonne; Mike Hall; Siobhan A. Wilson; Carolyn Greentree; Mikhail A. Fedonkin; David A. Elliott; Karl H. Hoffmann; Gabi I. C. Schneider Abstract Rangea is the type genus of the Rangeomorpha, an extinct clade near the base...

... the functional morphospace available to Ediacaran rangeomorphs. The first appearance of a cylindrical macroscopic stem in C. plumosa in the Briscal Formation of the Mistaken Point Ecological Reserve marks a significant departure from the modular repetitive branching typical of the Rangeomorpha, and exemplifies...

... that is reassessed here. The conclusion that continuous characters should not be included in generic diagnoses of the Rangeomorpha (Liu et al. 2016 ) has been contested through statistical analysis of the architecture of the rangeomorph Primocandelabrum from the UK, which can apparently have a range of types...

... Australia that, in addition to Dickinsonia , contains, with an intricate taphonomic history, the tubular Aulozoon and mat-like erniettomorph Phyllozoon . Aulozoon is formally described, and Dickinsonia rex redescribed. The fractal-like rangeomorpha are another important group of macroscopic...

... — Pectinifrons abyssalis n. gen. and sp. ROM 58148 from SH locality; 1, before; and 2, after retrodeformation. Retrodeformation achieved digitally by stretching the image perpendicular to cleavage by 160%. Scale bar is 10 mm. The Mistaken Point biota is dominated by members of the Rangeomorpha...

... are referred to as Rangeomorpha ( Anderson & Conway Morris, 1982 ; Jenkins, 1985 ; Narbonne & Gehling, 2003 ; Narbonne, 2004 ; Brasier & Antcliffe, 2004 ; O’Brien & King, 2004 ). It is interesting to note in this connection that biostratinomic evidence also suggests an infaunal in situ...

The new taxa are referred to the Rangeomorpha, defined by Pflug ( 1972 ) as a class, and considered an order by Jenkins ( 1985 ), but potentially...
