...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...

... (and morphologically similar) fronds from Charnwood Forest, UK, in “Revealing rangeomorph species characters using spatial analyses”. They propose that ecophenotypic variations could account for character differences between species, and provide new hypotheses to explain branching morphology within the Rangeomorpha...

... 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...

..., Email: [email protected] The Ediacaran biota of Newfoundland was dominated by the Rangeomorpha, named for the first described member of this clade, Rangea schneiderhoehni (Gürich, 1930 ; Pflüg, 1970 , 1972 ; Jenkins, 1985 ; Grazhdankin & Seilacher, 2005 ). This broad clade consists...

.... The fractal-like rangeomorpha are another important group of macroscopic Ediacaran fossils. Butterfield finds that three-dimensionally preserved Charnia from the White Sea possessed a bag-shaped morphology, with internal water-filled compartments interpreted as a hydrostatic exoskeleton. He argues...

...., 2019a ). Rangeomorpha consist of branches that are self-similar, fractal over at least three orders of magnitude, with all subsequent branching orders invariably at an acute angle to the previous branching order (Narbonne, 2004 ; Laflamme et al., 2007 ; Narbonne et al., 2009 ; Brasier et al., 2012...

... Museum (ROM) in Toronto before the locality obtained its official status, and are reposited in their collections under the specimen numbers listed. The new taxon is referred to the extinct stem-group taxon Rangeomorpha, originally described as a Class by Pflug in 1972 , but probably a higher order...

... in the similarly problematic and morphologically disparate Charnia Ford, 1958 , Bradgatia Boynton & Ford, 1995 , and several imperfectly described fusiform, frondose and plumose fossils from Newfoundland that together are referred to as Rangeomorpha ( Anderson & Conway Morris, 1982 ; Jenkins, 1985...
