Rycina: Shell of gastropod Desbruyeresia marisindica from Kairei hydrothermal vents in the Indian Ocean, covered with inorganic coatings (A), with cross section through this shell showing morphology of inorganic coatings (B) and close-up on a fragment showing structure and shell/coating spatial relations (C). Distribution of some elements (oxygen, manganese, calcium, iron, copper, and phosphorus) in a fragment of coating illustrated in (C) is shown in lower two rows.

The central chamber of the calcisphere is typically between 30 and 50 µm.

Figure: Variability in temperature measured in different species of rudist bivalves (upper plot) and well preserved specimen of Vaccinites vesciculosus (lower photo). Coloured violin plots indicate the spread in the full dataset, while black symbols indicate monthly mean values. Grey horizontal lines show the highest and lowest monthly mean value, respectively, through the entire dataset.

Z przyjemnością informujemy, że podczas Uroczystego Posiedzenia Naukowego Polskiej Akademii Umiejętności, które odbyło się 15 listopada, prof. Jarosław Stolarski, dyrektor Instytutu Paleobiologii PAN został uhonorowany godnością członka korespondenta Wydziału IV (Przyrodniczego).
Polska Akademia Umiejętności to jedna z najbardziej prestiżowych instytucji naukowych w Polsce, której historia sięga 1872 roku, kiedy to powstała jako Akademia Umiejętności z inicjatywy grona wybitnych uczonych i zatwierdzona przez cesarza Franciszka Józefa. Po II wojnie światowej jej działalność została ograniczona, jednak w 1989 roku dokonano jej pełnej reaktywacji, co pozwoliło przywrócić jej dawną pozycję w środowisku akademickim. PAU jest nie tylko instytucją naukową, ale także strażnikiem polskiego dziedzictwa intelektualnego, m.in. jest właścicielem Fototeki Lanckorońskich oraz współwłaścicielem bezcennej Bibilioteki Polskiej w Paryżu. Jej misją jest rozwój nauki na najwyższym poziomie oraz popularyzacja wiedzy wśród szerokiego grona odbiorców. https://pau.krakow.pl/index.php/pl/struktura/wydzialy-i-komisje/wydzial-iv-przyrodniczy

The direct ancestor of cowries 🐚😊
geojournals.pgi.gov.pl/asgp/article...
#geologia #paleontologia #paleontology #paleobiologia #paleobiology
A taxonomic revision of the extinct genus Zittelia from Jurassic sediments made it possible to trace a gradual evolutionary change in shell morphology: from the earliest species with an oval shell and elevated spire to later ones with a more globular form, in which the spire scarcely rises above the last whorl. The morphology of the aperture indicates an affinity of Zittelia with representatives of the cowries (superfamily Cypraeoidea), whose earliest members likewise appeared in the Late Jurassic.

Deep-sea corals: The future architects of reefs 🙂
www.nature.com/articles/s41...
#geologia #paleontologia #paleontology #paleobiologia #paleobiology
Figure: Scleractinian corals originated in the early Palaeozoic (~460 Ma) with solitary, likely heterotrophic forms such as Kilbuchophyllia. Many extant heterotrophic genera (e.g., Caryophyllia, Madrepora) arose in the Mesozoic, whereas photosymbiotic corals appeared in the Triassic (~240 Ma) and have repeatedly suffered environmental crises. Today, photosymbiotic reef builders such as Mussismilia again face extinction. Photo credits: Jarosław Stolarski (three images on the left-hand side); Marcelo V. Kitahara (Caryophyllia, Mussismilia); NOAA National Centers for Coastal Ocean Science (Expedition to the Deep Slope 2007).

Kiedy ryby zdominowały oceany? Odpowiedź paleontologów • Wszystko co najważniejsze
Morza w okresie jurajskim nie przypominały tych dzisiejszych, ponieważ wtedy dominowały głowonogi - twierdzą badacze z PAN.
