	Rangeomorph - Wikipedia, the free encyclopedia
		Rangeomorphs are an extinct, basal kingdom of soft-bodied creatures, neither animals nor plants that appeared 575 million years ago at the beginning of the Ediacaran period.
		Rangeomorphs were unable to move and had no reproductive organs, perhaps reproducing by dropping off new fronds.
		Rangeomorph communities are most similar to those of modern, suspension-feeding animals, but it is difficult to relate their morphology to any modern animals.

		Rangeomorphs are soft-bodied creatures, neither animals nor plants that appeared 575 million years ago at the beginning of the Ediacaran period.
		They survived about 30 million years, forming 80% of the fossils found from that period, until the Cambrian explosion of modern species after which they rapidly declined.
		They consist of branching "frond" elements each a few centimeters long, each of which is itself composed of many smaller branching tubes held up by a semi-rigid organic skeleton.

		Recent comparison of rangeomorph structure with the radial canals of fossil and recent ctenophores seems remote from a morphological standpoint and is also inconsistent with the internal organic skeletons documented above.
		Rangeomorphs occur only sporadically in younger Ediacaran assemblages, perhaps as a result of competition with early animals, and have not been reported from any Phanerozoic assemblage including fossil Lagerstätten such as the Burgess Shale.
		It is difficult to relate rangeomorphs to any modern group of macroscopic organisms, and they appear to represent a "forgotten" architecture and construction that characterized early stages in the terminal Neoproterozoic evolution of complex multicellular life.

	COMPLEX MULTIFOLIATE EDIACARAN FRONDS FROM MISTAKEN POINT NEWFOUNDLAND, CANADA
		Among the myriad of highly ornamented Precambrian Ediacara Biota, the rangeomorphs constitute the most complex bauplan, due in part to their innate “fractal quilting” that highlights a repetitive pattern that is identical over at least three orders of branching.
		Rangeomorphs have a worldwide distribution, with known examples from Australia, Russia, Namibia, England, and most notably from Mistaken Point Newfoundland, where they constitute the overwhelming majority of the diversity and abundance of the Ediacaran Biota present.
		Specimens of a new species of Ediacaran rangeomorph frond preserved in thin and thick ash (two different types of Conception-style positive epirelief preservation) from Mistaken Point, in addition to previously unknown specimens preserved in Flinders-style positive hyporelief from the Sheepbed Fm.

	AAAS - AAAS News Release
		The earliest complex life forms (575 - 560 million years old) were built of "rangeomorph modules," which show a fractal-like branching pattern of tubes ranging from a few millimeters to less than 100 micrometers in diameter.
		These were used as modules to construct centimeter- to meter-scale colonies that formed some of the earliest animal ecosystems.
		Like other so-called "rangeomorph" fossils found at Mistaken Point, these organisms appear somewhat plant-like, with leafy structures called "frondlets" branching from stems.

		Since we want lots of land aminals and plant analogues, to begin with we'll look at constructing a biosphere in the later end of that timespan, although along the way we'll be coming up with primitive forms that can later be used to fill in the earlier periods.
		Rangeomorph plant analogues are likely to provide quite a bit of room for designing carnivorous plants as well.
		Rangeomorphs are by definition extremely simple, modular creatures, and can be made to fit the roles of either animals or plants.

		The main building block of the rangeomorph organisms is the cm-scale "rangeomorph frondlet", and each such frondlet consists of smaller branches, with a total of three or more orders of fracticality.
		No evidence of reproductive organs has been found in the Spaniards Bay specimens and Narbonne (2004) speculates that the organisms may have reproduced vegetatively from fronds that either fell off or were broken off from an existing organism.
		Although the rangeomorphs appear to have dominated life during the middle Ediacaran, they are rare in the later Ediacaran, and have not been observed in Cambrian and younger rocks.

		The inside of the tube is the 'gut', one end is the 'mouth' and the other is the 'anus').
		They're grouped under the designation Rangeomorphs and may be distantly related to modern day corals and jellyfish (Cnidaria).
		The oldest known metazoan fossils (Top) are ring like impressions dated to 600 million years ago and may represent the anchor points of early rangeomorph stalks.

	Images for Chapter 5 The Cambrian Explosion
		A new concept by Guy Narbonne that many early Ediacaran animals were modular, consisting of frond-like structures that were grown in many different ways to yield many different-looking fossils, often large ones.
		However, they were all variations on a theme, so can be considered as an evolutionary group, the rangeomorphs.
		Their zoological affinities remain uncertain, though they are probably not outrageously different in an ecological sense from colonial creatures like many cnidarians.
