| The dark phosphate bed of Weng'an contains a well-preserved, diverse floral assemblage including multicellular thallophytes, acritarchs, and cyanophytes. |
| Studies of acritarchs and chitinozoans suggest Ordovician to Silurian ages. |
| Ediacaran acritarchs also have many similarities with Glomeromycotan vesicles and spores. |
| Acritarchs continue to be used in studies of Proterozoic paleoecology and stratigraphy, even though their systematic affinities are still not well understood. |
| Our picture of Precambrian marine diversity is dominated by small fossils known as acritarchs. |
