Belongs within: Diaphoretickes.Contains: Bigyra, Pseudofungi, Diatomista, Chrysista, Alveolata, Cercozoa, Endomyxa, Radiozoa, Foraminifera. The Sar clade is a group of protists united by molecular data, named for the initials of the major subclades Stramenopiles, Alveolata and Rhizaria. It has been defined as the least inclusive clade containing Bigelowiella natans, Tetrahymena thermophila and Thalassiosira pseudonana but not… Continue reading Sar


Belongs within: Oligohymenophorea. The model tetrahymenidans Published 15 November 2019 Ciliates have long been one of the most (if not the most) confidently recognised groups of unicellular eukaryotes owing to their distinctive array of features, in particular locomotion by means of more or less dense tracts of small cilia that often run the length of… Continue reading Tetrahymenida


Belongs within: Mediophyceae.Contains: Stephanodiscus, Thalassiosira. United by silicon tubes Published 12 March 2024 Diatoms are among the most instantly recognised of all aquatic micro-organisms. Their architectural silica tests are unique in the microbial biosphere. They are also among the most abundant organisms in many waters and play a pivotal role in the global distribution of… Continue reading Thalassiosiraceae

Belongs within: Streptophyta.Contains: Cingulati, Zonati, Pollenites, Apo-Tracheophyta, Marchantiophyta, Bryophyta, Anthocerotopsida. The clade Embryophyta contains the land plants, the dominant producers of the terrestrial environment. These organisms were able to thrive out of the water due to the retention and fertilisation of their eggs within protective structures, though less derived forms remain dependent on damp conditions… Continue reading Embryophyta


Belongs within: Rotaliida.Contains: Anomalinidae, Trichohyalidae, Gavelinella, Parrelloididae, Discorbinellidae, Cancrisidae, Eponididae, Rosalinidae. The Siphoninidae are a group of Foraminifera known from the Eocene to the present, commonly bearing a frilled keel around the outer edge of the test (Loeblich & Tappan 1964). <==RosalinidaM13 |–GavelinelloideaM13 | |–AnomalinidaeM13 | |–TrichohyalidaeM13 | |–GavelinellidaeM13 | | |–GavelinellaM13 | | |–Brotzenella… Continue reading Rosalinida


Belongs within: Diaphoretickes. The Ischyrospongia were originally recognised as a grouping of hypercalcified sponges including the sclerosponges and stromatoporoids. Some subsequent authors have also placed a number of Palaeozoic microfossils of uncertain affinities within this taxon. These include the Moravamminida in which the test is divided by septa or pseudosepta and has a calcareous, hyaline… Continue reading Ischyrospongia


Belongs within: Diaphoretickes. The Vendophyceae are a grouping (largely of convenience) of multicellular fossil algae known from the Ediacaran (late Precambrian). Members of this group include the ribbon-like Vendotaeniales, and the compressed tubular Archyfasma. Archyfasma dimera preserves a thallus internally differentiated between a cortex and medulla, as seen in modern algal species (Gnilovskaya 2003). Characters… Continue reading Vendophyceae


Belongs within: Eukaryota.Contains: Vendophyceae, Ischyrospongia, Haptista, Corbihelia, Sar, Cryptista, Conferva, Rhodophyta, Glaucophyta, Chlorophyta, Streptophyta. The Diaphoretickes are a clade of eukaryotes supported by molecular phylogenies that might be described as comprising the major algal lineages and related taxa. Cavalier-Smith et al. (2015) defined an equivalent clade under the name Corticata as including all descendents of… Continue reading Diaphoretickes


Belongs within: Diaphoretickes.Contains: Proteorhodophytina, Bangiales, Florideophycidae. The Rhodophyta include the red algae, a major group of aquatic photosynthetic organisms. Many red algae are multicellular (forming the clade Eurhodophytina) but the taxon also includes a number of unicellular or filamentous lineages. Cells lack cilia and associated organelles at all stages of the life cycle (Adl et… Continue reading Rhodophyta
