 Occurrence of Fermeuse formation in southeast Newfoundland | |
The Fermeuse Formation is a fossil-bearing Ediacaran geologic formation in Newfoundland.
On Avalon Peninsula [1] there is low diversity, and includes rare trace fossils, Palaeopascichnus , [3] and Aspidella discs, sometimes in great concentrations. [4]
On Bonavista Peninsula there is higher diversity, including more fronds (rangeomorphs) and better preserved than on Avalon Peninsula. [1]
On Bonavista Peninsula the depositional environment was a slope and outer shelf–below photic zone Turbidites probably were the dominant sediment transporters. [4]
It is predominantly silts and sands, in contrast to underlying Trepassey Formation, which is mostly dark grey shales. There is a coarsening up sequence throughout the two formations, such that the top of the Fermeuse is predominantly sandstones. [4]
On Avalon Peninsula there were much shallower waters, particularly than in underlying Mistaken Point Formation and Trepassey Formation. [1] It is indicated by sandy channel fills, slumping, occasional silts. [1] There is a possible delta front and shallow slope setting. [1]
Division 1, Newfoundland and Labrador is a census division covering the entire Avalon Peninsula including the Isthmus of Avalon of the Canadian province of Newfoundland and Labrador. Like all census divisions in Newfoundland and Labrador, but unlike the census divisions of some other provinces, the division exists only as a statistical division for census data, and is not a political entity.
The East Coast Trail (ECT) is a long-distance coastal footpath located in the Canadian province of Newfoundland and Labrador. It is a developed trail over 336 kilometres (209 mi) long, creation of which began in 1994. It is made up of 25 linked wilderness paths and passes through more than 30 communities. It was named one of the best adventure destinations by National Geographic in 2012 and is extended and improved yearly.
Mistaken Point Ecological Reserve is a wilderness area and a UNESCO World Heritage Site located at the southeastern tip of Newfoundland's Avalon Peninsula in the Canadian province of Newfoundland and Labrador. The reserve is home to the namesake Mistaken Point Formation, which contains one of the most diverse and well-preserved collections of Precambrian fossils in the world. Ediacaran fossils discovered at the site constitute the oldest known remnants of multicellular life on Earth.
Primocandelabrum is a genus of rangeomorph known from the Avalon-type Ediacaran biota. It makes up the brunt of some bedding plane assemblages. Primocandelabrum was described by Hofmann, O'Brien, and King in 2008.
The Forteau Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the Cambrian period.
The Briscal Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period.
The Drook Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period. It contains a stratum dated to 575.8 ± 0.5 million years ago.
The Gaskiers Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period.
The Mistaken Point Formation is a geologic formation in Newfoundland and Labrador. It is recognized as a Lagerstätte preserving fossils dating back to the Ediacaran period. It contains a stratum dated to 565 ± 3 million years ago.
The Renews Head Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period.
The Trepassey Formation is a geologic formation that crops out in Newfoundland. It preserves fossils dating back to the Ediacaran period.
The Conception Group is a geologic group in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period. It mainly contains turbidites, but is interrupted by a glacial diamictite, and tops out with sand and siltstones. It corresponds to the lower portion of the Connecting Point Group.
The St John's Group is a fossiliferous shale-dominated Ediacaran geologic group in Newfoundland and Labrador, younger than 565 ± 3 million years ago.
Haootia quadriformis is an extinct animal belonging to the Ediacaran biota. Estimated to be about 560 million years old, H. quadriformis is identified as a cnidarian polyp, and represents the earliest known evidence for muscle tissue in an animal. Discovered in 2008 from Newfoundland in eastern Canada, it was formally described in 2014. It is the first Ediacaran organism discovered to show fossils of muscle fibres. Structural examination of the muscles and morphology indicate that the animal is a cnidarian, though, which class H. quadriformis belongs to is currently undetermined.
The Random Formation is a rock unit in Newfoundland dating to the early Cambrian period, dominated by tidal quartz arenites deposited in a near-shore environment, but also incorporating intertidal and open-shelf deposits, including glauconitic and mud-cracked mudstones, and red channel sandstones. It was deposited quickly and is approximately 175 m thick. The Blue Pinion Formation was originally recognized as a separate formation, but is now interpreted as an expression of the Random Formation.
The Mall Bay Formation is an Ediacaran formation, cropping out in Newfoundland and possibly elsewhere. It is part of the Conception Group, underlying the Gaskiers Formation.
The Signal Hill Group is a siliciclastic Group of marine Ediacaran strata, cropping out in Newfoundland, in the eastern Bonavista Peninsula and the eastern Avalon peninsula.
Parviscopa is a genus of frondose forms characterized in 2008 based on specimens from Newfoundland, Canada. Parviscopa is a member of the Ediacaran biota, and is more specifically part of the Avalon type assemblage, which is from the older part of the Ediacaran and is characterized by deep water deposits.
Trepassia is a 579 million-year-old fossil of Ediacaran rangeomorph. It was first discovered by Guy M. Narbonne, a professor at Queen's University in Ontario, Canada and colleagues in 2009. Three years later, Martin D. Brasier added additional description to Trepassia. The generic name is taken from the French word, trépassés, which translates to "those that have departed forever" and honors the Trepassey community in Newfoundland. It was originally described as Charnia wardi; it was referred under this synonym in a 2016 paper.
Hadrynichorde is a frondose organism from the Ediacaran period discovered in Newfoundland, Canada. It is a sessile, benthic marine organism. resembling modern sea whips.
