... gradients chiefly by its effect on species’ range limits rather than on probabilities of speciation and extinction. We show that this mechanism also appears to operate in various multicellular taxa, thus providing a widely applicable explanation for the origin of latitudinal diversity gradients. Copyright...

... loop at one end and opening with a slight divergence at the opposite end. The ridges are interpreted as casts of sediment-laden mucus strings formed by the movement of multicellular or syncytial organisms along a muddy surface. The taxa Myxomitodes stirlingensis n. igen., n. isp., are introduced...

...Emily G. Mitchell; Nicholas J. Butterfield Abstract Bedding-plane assemblages of Ediacaran fossils from Mistaken Point, Newfoundland, are among the oldest known records of complex multicellular life on Earth (dated to ~565 Ma). The in situ preservation of these sessile but otherwise deeply...

... and recumbent forms. This suggests a very rapid radiation of Rangeomorpha bodyplans into an open (or minimally constrained) ecosystem for macroscopic multicellular organisms ( Narbonne et al. 2009 ; Hoyal Cuthill and Conway Morris 2014 ). The loss of recumbent Rangeomorpha taxa could be explained by several...

...Catherine E. Boddy; Emily G. Mitchell; Andrew Merdith; Alexander G. Liu Abstract Macrofossils of the late Ediacaran Period ( c. 579–539 Ma) document diverse, complex multicellular eukaryotes, including early animals, prior to the Cambrian radiation of metazoan phyla. To investigate...

... of the nearly 100 specimens are juvenile rangeomorphs, an extinct Ediacaran clade that numerically dominated the early evolution of complex multicellular life. Spaniard's Bay rangeomorphs are characterized by cm-scale architectural elements exhibiting self-similar branching over several fractal scales that were...
