Avalon explosion, the Glossary

The Avalon explosion, named from the Precambrian faunal trace fossils discovered on the Avalon Peninsula in Newfoundland, eastern Canada, is a proposed evolutionary radiation of prehistoric animals about 575 million years ago in the Ediacaran period, with the Avalon explosion being one of three eras grouped in this time period.^[1]

Animal

Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia.

Annelid

The annelids (Annelida, from Latin anellus, "little ring"), also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches.

Bilateria

Bilateria is a large clade or infrakingdom of animals called bilaterians, characterized by bilateral symmetry (i.e. having a left and a right side that are mirror images of each other) during embryonic development.

A body plan, Bauplan, or ground plan is a set of morphological features common to many members of a phylum of animals.

See Avalon explosion and Body plan

Cambrian explosion

The Cambrian explosion (also known as Cambrian radiation or Cambrian diversification) is an interval of time approximately in the Cambrian period of the early Paleozoic when a sudden radiation of complex life occurred, and practically all major animal phyla started appearing in the fossil record. Avalon explosion and Cambrian explosion are evolution of the biosphere and Unsolved problems in biology.

Carboniferous

The Carboniferous is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma.

Charles Darwin

Charles Robert Darwin (12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology.

Charnwood Forest

Charnwood Forest is a hilly tract in north-western Leicestershire, England, bounded by Leicester, Loughborough and Coalville.

Cnidaria

Cnidaria is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.

See Avalon explosion and Cnidaria

Eastern Canada

Eastern Canada (Est du Canada, also the Eastern provinces, Canadian East or the East) is generally considered to be the region of Canada south of Hudson Bay/Hudson Strait and east of Manitoba, consisting of the following provinces (from east to west): Newfoundland and Labrador, Nova Scotia, Prince Edward Island, New Brunswick, Quebec and Ontario.

Echinoderm

An echinoderm is any deuterostomal animal of the phylum Echinodermata, which includes starfish, brittle stars, sea urchins, sand dollars and sea cucumbers, as well as the sessile sea lilies or "stone lilies".

Ediacaran

The Ediacaran is a geological period of the Neoproterozoic Era that spans 96 million years from the end of the Cryogenian Period at 635 Mya to the beginning of the Cambrian Period at 538.8 Mya.

See Avalon explosion and Ediacaran

Ediacaran biota

The Ediacaran (formerly Vendian) biota is a taxonomic period classification that consists of all life forms that were present on Earth during the Ediacaran Period. Avalon explosion and Ediacaran biota are Ediacaran life.

Evolutionary radiation

An evolutionary radiation is an increase in taxonomic diversity that is caused by elevated rates of speciation, that may or may not be associated with an increase in morphological disparity.

See Avalon explosion and Evolutionary radiation

Fauna

Fauna (faunae or faunas) is all of the animal life present in a particular region or time.

See Avalon explosion and Fauna

Fractofusus misrai

Fractofusus misrai is an Ediacaran fossil discovered in 1967 by S.B. Misra at Mistaken Point, Newfoundland and Labrador, Canada, which has since become the Mistaken Point Ecological Reserve. Avalon explosion and Fractofusus misrai are Ediacaran life.

Great Ordovician Biodiversification Event

The Great Ordovician Biodiversification Event (GOBE), was an evolutionary radiation of animal life throughout the Ordovician period, 40 million years after the Cambrian explosion, whereby the distinctive Cambrian fauna fizzled out to be replaced with a Paleozoic fauna rich in suspension feeder and pelagic animals.
