	Maotianshan shales - Wikipedia, the free encyclopedia
		The Maotianshan shale is a lower Cambrian (Atdabanian) rock formation, of ca 522 Mya, now lying exposed in the Yunnan Province of China in the villages of Ercaicun and Chengjiang near the city of Kunming.
		The shales contain a very broad and well-preserved fauna including many of the taxa found in the better known, and substantially younger, Burgess Shale of British Columbia, as well as the somewhat younger Emu Bay shale of South Australia.
		The Maotianshan shales provide even stronger evidence than does the Burgess shale for a Cambrian Explosion wherein a large number of very different animal body plans seem to have appeared in a disconcertingly short time interval.

		The Maotianshan shale is an Early Cambrian rock formation exposed in Yunnan Province in China in the villages of Ercai and Chenjiang near the city of Kunming.
		In addition to Anomalocaris, Opabinia, Hallucigenia, and other spectacular forms familiar from the Burgess shales, the Maotianshan shales include at least four types of chordates, two which appear to be true fishes.

	Burgess shale
		The Burgess Shale is a fl shale found high up in the Canadian Rockies in Yoho National Park near the town of Field, British Columbia.
		The diversity and exotic nature of the Burgess fauna has caused a great deal of controversy in paleontology with regard to the reasons for and nature of what has come to be called the Cambrian Explosion.
		The deposits appear to represent small areas of muddy ocean bottom that -- from time to time -- slid down the face of a limestone cliff, carrying their fauna and anything unfortunate enough to be swimming by into oxygen-poor waters in the depths.

	Opabinia: Definition and Links by Encyclopedian.com (Site not responding. Last check: 2007-11-04)
		It is known only from two fossil beds -- the Middle Cambrian Burgess Shale of British Columbia, and the Lower Cambrian Maotianshan shales of Yunnan, China.
		Although Opabinia is a relatively minor constituent of the early faunas it has historical significance because it was one of the first truly unusual animals to be completely studied and described when redescription of the Burgess shale faunas was undertaken in the 1970s.
		Harry Whittington[?] showed pretty convincingly in 1975 that the animal, previously thought to be an arthropod, was not an arthropod and moreover that it was unlikely that it belonged to any other known phylum.

		Two types of an Early Cambrian animal with apparent fins, vertebrate musculature, and with gills are known from the Early Cambrian Maotianshan shales of China - Haikouichthys and Myllokunmingia.
		A possible agnathid that has not been formally described was reported by Simonetti from the Middle Cambrian Burgess Shale of British Columbia.
		Agnathids were well established by the late Ordovician and are found in the Silurian as well.

	Fossils of Chengjiang China Maotianshan shale (Site not responding. Last check: 2007-11-04)
		The Chengjiang lagerstatte in the Yunning Province of China, also known as the Chengjiang Biota or the Maotianshan shales) is an extraordinary fossil site providing the oldest Cambrian occurrence of diverse and well-preserved soft-bodied metazoan fossils.
		The fossils of the Maotianshan shale and Burgess Shale Fauna of Field, British Columbia (~515 million years ago) provide a lens to view the appearance on earth of all the major phyla in existence today, organisms that remain of enigmatic origin, and forms that did not persist.
		Although fossils from the region have been known since the early 1900s, it was the discovery of the trilobitiform Naraoia longicaudata on July 1, 1984 by Hou Xian-guang that led to the recognition of this exceptional soft-body lagerstatte.

		The best studied sites where soft parts of organisms have fossilized are in the Burgess shale of British Columbia.
		Fairly extensive pre-Cambrian Ediacarian faunas have been identified in the past 50 years, but their relationships to Cambrian forms are quite obscure.

	Hallucigenia: (Site not responding. Last check: 2007-11-04)
		Hallucigenia is an extinct genus of animal found as fossils in the Middle Cambrian-aged Burgess Shale formation of British Columbia, Canada.
		In 1991, Ramiskold and Hou Xianguang, working with additional specimens of a "hallucigenid" from the lower Cambrian Maotianshan shales of China, reinterpreted Hallucigenia as an Onychophore.
		Interestingly, none of the 30 or so known Burgess Shale specimens shows any sign of pairing in the large tentacles; nor do their Chinese counterparts.

		The Myllokummingia is a primitive, probably agnathid (jawless) fish from the Lower Cambrian Maotianshan shales of China thought to be a vertebrate (see external links).
		The first armored agnaths—the Ostracoderms, precursors to the bony fish and hence all tetrapods, including human beings—are known from the middle Ordovician, and by the Late Silurian the agnaths had reached the high point of their evolution.
		The Maotianshan shale is a late pre-Cambrian (Atdabanian) rock formation, of ca 522 Mya, now lying exposed in the Yunnan Province of China in the villages of Ercaicun and Chengjiang near the city of Kunming.

		The Burgess Shale (named after Mount Burgess, close to where the Shale was found) is a fl shale exposure found high up in the Canadian Rockies in Yoho National Park near the town of Field, British Columbia.
		Fossils were found in the Burgess Shale by Charles Doolittle Walcott in 1909.
		Gould suggests that the extraordinary diversity of the fossils indicate that life forms at the time were much more diverse than those that survive today and that many of the unique lineages were evolutionary experiments that became extinct.
