Exceptionally well-preserved non-lithistid demosponge body fossils are reported from outcrops of the late Eocene Pallinup Formation, Fitzgerald River National Park, south-western Australia. Among 11 species, eight are new to science and belong to heteroscleromorph orders: Bubarida (Eolipastrotethya picketti gen. et sp. nov., Monocrepidium unispiculatum sp. nov. and M. pauli sp. nov.), Axinellida (Phycopsis arbusculum sp. nov.) and Tetractinellida (Triptolemma solida sp. nov., Pachastrella… 

High diversity of siliceous sponges in Western Tethyan areas during the Eocene: palaeobiogeographical, ecological and taxonomic significance

Porifera is a clade of globally distributed, early diverging metazoans that are important components of modern aquatic environments. Despite the fact that they were also abundant in the geological

Further Mollusca from the late Eocene Pallinup Formation, Eucla Basin, Western Australia

The composition of the fauna shows that the Eucla Basin in the late Eocene was within the Southern Australian Province (70% of the genera present characteristic of the Province) and Seraphs is recorded for the first time from the Australian Tertiary.

Uncovering the hidden diversity of Paleogene sponge fauna of the East European Platform through reassessment of the record of isolated spicules

Despite being reported from various localities and stratigraphic intervals, knowledge of the siliceous sponges from the Cenozoic of Eastern Europe remains surprisingly limited. Studies assessing

Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model

This study uses desma-bearing sponges, a diverse group of demosponges that form rigid skeletons and have a rich and continuous fossil record dating back to the Cambrian, to date the demosponge radiation and constrain the timing of key evolutionary events, like the transition from marine to freshwater habitats.

Utilizing sponge spicules in taxonomic, ecological and environmental reconstructions: a review

The silicon isotope compositions in spicules are being increasingly often used to estimate the level of silicic acid in the marine settings throughout the geological history, which enables to reconstruct the past silica cycle and ocean circulation.

Marine Sponge (Porifera: Demospongiae) Liosina paradoxa Thiele, 1899 from Sandspit backwater mangroves at Karachi coast, Pakistan

The result has been shown that the species is Liosina paradoxa (Family Dictyonellidae) first time reported from coastal area of Pakistan.

Surface Microornamentation of Demosponge Sterraster Spicules, Phylogenetic and Paleontological Implications

The fossil record suggested that Geodiidae was present at least since the Middle Jurassic (163–166 Mya), while Geodia sterrasters were present since the Santonian/Campanian boundary, Late Cretaceous (83.6 Mya).



A highly diverse siliceous sponge fauna (Porifera: Hexactinellida, Demospongiae) from the Eocene of north-eastern Italy: systematics and palaeoecology

This study extends the geographical and stratigraphical range of many sponge taxa, including Camerospongia, Toulminia, Ozotrachelus and Bolidium, previously documented only from the Cretaceous, before being reported here in the Cenozoic for the first time.

The sponge genus Brachiaster (Pachastrellidae, Demospongiae) and its first known fossil representative, from the late Eocene of southwestern Australia

Brachiaster claudelevii has well-developed axial canals in the mesotriders, which points to it being intermediate in character between the typical tetraxial desmas of lithistids, and tetraxia spicules of non-lithistid demosponges, which further supports the position of Brachiaster among the Pachastrellidae.

Late Eocene siliceous sponge fauna of southern Australia: reconstruction based on loose spicules record.

The diversity of spicules is similar in all studied samples and areas, even distant geographically, and there are only minor differences between the sections, which indicates a homogenous character of this rich siliceous sponge assemblage.

Bathyal sponges from the late Early Miocene of the Vienna Basin (central Paratethys, Slovakia)

This sponge fauna has clear Tethyan affinities and indicates the existence of connection between Paratethys and Tethys during the latest Burdigalian, as well as the presence of open marine, deep-water, bathyal conditions in this part of the Vienna Basin.


The Miocene (middle Serravalian) Mem Moniz marls from Algarve (Portugal) contain a rich and well preserved assemblage of siliceous sponge spicules, which is described here for the first time. The

Taxonomy, phylogeny and biogeography of the marine sponge genus Acarnus (Porifera, Poecilosclerida)

Six regional Acarnus forms are described as new species, and the phylogenetic history of the genus is reconstructed with cladistic techniques, using morphological characters of original as well as unpublished material together covering almost all described taxa from all over their known ranges.

Axinellida (Porifera: Demospongiae) from the New Caledonia lagoon

Two species, Axinella carteri (Dendy) and Astrosclera willeyana Lister, were found to be truly widely distributed throughout the Indo-Pacific, typically associated with coral reefs; other previously suspected widely distributed species were generally found to been allopatric, cryptic sibling species related to the tropical Australasian fauna.

Tethyan relicts on continental coastlines of the northwestern Pacific Ocean and Australasia: molecular phylogeny and fossil record of batillariid gastropods (Caenogastropoda, Cerithioidea)

A definition of the family using shell characters, as a basis for a review of the extensive fossil record, is proposed and a revised generic classification consistent with the phylogenetic hypothesis is suggested.
