Lingulella Davisi
''Lingulella'' is a genus of phosphatic-shelled brachiopod. It is known from the Middle Cambrian Burgess Shale (Canada) to the Upper Ordovician Bromide Formation (United States) in North America.Amsden, T.W. Catalogue of Fossils from the Middle and Upper Ordovician of Oklahoma. Oklahoma Geological Survey, Circular 43. 1957 346 specimens of ''Lingulella'' are known from the Greater Phyllopod bed, where they comprise 0.66% of the community. Some specimens of the brachiopod preserve the pedicle intact, which was long and thin. The brachiopod is thought to have been a generalist, as it appears consistently throughout the strata of the Greater Phyllopod bed.

Lingula Davisii
Lingula, Latin for "little tongue", may refer to: * ''Lingula'' (brachiopod), a brachiopod genus of the family Lingulidae, which is among the few brachiopods surviving today but also known from fossils over 500 million years old * A wide strap above the instep in sandals * In anatomy: ** the Lingula of left lung, one of the segments of the left lung with a tongue-shape ** The Sphenoidal lingula, a part of the sphenoid bone ** The Lingula of mandible, a ridge on the medial aspect of the body of the mandible, just anterior to the mandibular foramen ** the Lingula of cerebellum ** Taenia of fourth ventricle ** In the vasiform orifice of the Aleyrodidae Whiteflies are Hemipterans that typically feed on the undersides of plant leaves.

Cambrian British Columbia
The Cambrian ( ) is the first geological period of the Paleozoic Era, and the Phanerozoic Eon. The Cambrian lasted 51.95 million years from the end of the preceding Ediacaran period 538.8 Ma (million years ago) to the beginning of the Ordovician Period 486.85 Ma. Most of the continents lay in the southern hemisphere surrounded by the vast Panthalassa Ocean. The assembly of Gondwana during the Ediacaran and early Cambrian led to the development of new convergent plate boundaries and continental-margin arc magmatism along its margins that helped drive up global temperatures. Laurentia lay across the equator, separated from Gondwana by the opening Iapetus Ocean. The Cambrian marked a profound change in life on Earth; prior to the Period, the majority of living organisms were small, unicellular and poorly preserved. Complex, multicellular organisms gradually became more common during the Ediacaran, but it was not until the Cambrian that fossil diversity seems to rapidly increase ...
