Burgessochaeta is an extinct genus of polychaete annelids from the Middle Cambrian. Its fossils have been found in the Burgess Shale in British Columbia, Canada. A total of 189 specimens of Burgessochaeta are known from the Greater Phyllopod bed, where they comprise 0.36% of the community. Specimens have also been found at Marble Canyon. The genus was described by Conway Morris (1979) and re-examined by Eibye-Jacobsen (2004).
Dalyia is a pterobranch known from the middle Cambrian Burgess shale. It was previously interpreted as a red alga. It has smooth or faintly lineated stems, which branch into up to four equal branches at branching points. 37 specimens of Dalyia are known from the Greater Phyllopod bed, where they comprise 0.07% of the community.
Liangshanella is a genus of Cambrian bradoriid known from the Chengjiang biota and Burgess Shale. 6263 specimens of Liangshanella are known from the Greater Phyllopod bed, where they comprise 11.9% of the community.
Morania is a genus of cyanobacterium preserved as carbonaceous films in the Middle Cambrian Burgess Shale. it is present throughout the shale; 2580 specimens of Morania are known from the Greater Phyllopod bed, where they comprise 4.90% of the community. It is filamentous, forms sheets, and resembles the modern cyanobacterium Nostoc. It would have had a role in binding the sediment, and would have been a food source for such organisms as Odontogriphus and Wiwaxia.
The Phyllopod bed, designated by USNM locality number 35k, is the most famous fossil-bearing member of the Burgess Shale fossil Lagerstätte. It was quarried by Charles Walcott from 1911–1917, and was the source of 95% of the fossils he collected during this time; tens of thousands of soft-bodied fossils representing over 150 genera have been recovered from the Phyllopod bed alone.
Chaunograptus is a genus of putative graptolite known from the Middle Cambrian Burgess Shale. 11 specimens of Chaunograptus are known from the Greater Phyllopod bed, where they comprise 0.02% of the community.
Falospongia is a genus of sponge made up of radiating fronds, known from the Middle Cambrian Burgess Shale. Its name is derived from the Latin fala ("scaffold") and spongia ("sponge"), referring to the open framework of the skeleton. It superficially resembles Haplistion but is monaxial. 5 specimens of Falospongia are known from the Greater Phyllopod bed, where they comprise under 0.1% of the community.
Halichondrites, sometimes mis-spelt Halicondrites is an extinct genus of sea sponge known from the Middle Cambrian Burgess Shale. 7 specimens of Halichondrites are known from the Greater Phyllopod bed, where they comprise < 0.1% of the community.
Hanburia gloriosa is a corynexochid trilobite known from the Middle Cambrian Burgess Shale. Four specimens of Hanburia gloriosa are known from the Greater Phyllopod bed, where they comprise < 0.1% of the community.
Mackenzia is an elongated bag-like animal known from the Middle Cambrian Burgess Shale. It attached directly to hard surfaces, such as brachiopod shells. 14 specimens of Mackenzia are known from the Greater Phyllopod bed, where they comprise <0.1% of the community. Mackenzia was originally described by Charles Walcott in 1911 as a holothurian echinoderm. Later, Mackenzia is thought to be a cnidarian and appears most similar to modern sea anemones.
Micromitra is a genus of brachiopods known from the Middle Cambrian Burgess Shale. 160 specimens of Micromitra are known from the Greater Phyllopod bed, where they comprise 0.3% of the community.
Leptomitus is a genus of demosponge known from the Middle Cambrian Burgess Shale. Its name is derived from the Greek lept ("slender") and mitos ("thread"), referring to the overall shape of the sponge. 138 specimens of Leptomitus are known from the Greater Phyllopod bed, where they comprise 0.26% of the community.
Insolicorypha is a genus of polychaetes known from the Middle Cambrian Burgess Shale. A single specimen of Insolicorypha is known from the Greater Phyllopod bed. The genus was described by Conway Morris (1979) and re-examined by Eibye-Jacobsen (2004).
Oesia disjuncta is a monospecific genus of hemichordate known from the Middle Cambrian Burgess Shale. 1147 specimens of Oesia are known from the Greater Phyllopod bed, where they comprise 2.18% of the community. It was previously compared to the chaetognaths.
