This page represents the following TreeOfLife-200M taxonomic path.[1]
GBIF’s associated museum imagery for Acanthochaetetes seunesi is indexed as “Museum Specimen: Invertebrate Zoology” (basis of record: FOSSIL_SPECIMEN).
The TreeOfLife-200M image set contains museum-photography records that depict the preserved, hypercalcified skeletal material characteristic of chaetetid-type demosponges (i.e., the fossil context for Acanthochaetetes sensu the chaetetid-type framework). [1]
GBIF treats Acanthochaetetes seunesi (authorship Fischer, 1970) as an accepted species name under usage key 4980559. [2]
In a revised treatise on fossil chaetetid-type hypercalcified demosponges, West emphasizes that the “chaetetid-type” skeleton grade is characterized by a rigid basal calcareous skeleton that is typically spicule-poor/aspicular, and discusses external skeletal features such as mamelons and astrorhizae for interpreting chaetetid skeletons. [3]
The same treatise also cautions that historical higher-level placement based on “chaetetid-type” skeleton morphology encountered problems because fossil chaetetids are often spicule-poor/absent and because superficially similar hypercalcified skeletons can occur in different groups; it also notes that subclass-level groupings used historically may be polyphyletic, so reliance on those groupings should be abandoned.
