Exempel på hur man kan använda ACRITARCHS i en mening

• A wide array of late Precambrian fossils have been recovered from the group, including stromatolites, vase-shaped microfossils, acritarchs and macro fossils such as Tawuia.
• While every kingdom of life is represented in the microfossil record, the most abundant forms are protist skeletons or microbial cysts from the Chrysophyta, Pyrrhophyta, Sarcodina, acritarchs and chitinozoans, together with pollen and spores from the vascular plants.
• This discovery reinforces the earlier suggestion that the migration of land plants from northern Gondwana to Baltica in the Late Ordovician was facilitated by the northward migration of Avalonia, which is evidenced by the co-occurrence of reworked, Early–Middle Ordovician acritarchs, possibly suggesting an Avalonian provenance in a foreland basin system.
• The 'Kildonnan Member' of the Lealt Shale Formation contains stromatolites and various microfossils such as dinoflagellates and acritarchs.
• In some of the gray and black mudrocks, paleontologists have found an abundance of organic microfossils, including vase-shaped microfossils (VSMs) likely presentative of arcellinid testate amoebae, acritarchs, "Sphaerocongregus variabilis", and organic chemicals characteristic of dinoflagellates.
• He first described chitinozoans and many species of acritarchs, dinoflagellate cysts and graptolites.
• Although most of the Group is unfossiliferous (without fossils), locally sparse graptolite faunas and acritarchs have been found.
• Harvey (2023) interprets a well-preserved assemblage of acritarchs from the Cambrian Stage 4 Forteau Formation (Canada) as fossil material of planktic green algae with coenobial colony formation.
