- Foraminifera - Wikipedia
Foraminifera ( f ə ˌ r æ m ə ˈ n ɪ f ə r ə fə-RAM-ə-NIH-fə-rə; Latin for "hole bearers"; informally called "forams") are single-celled organisms, members of a phylum or class of Rhizarian protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell (called a "test") of

Foraminifera (‘hole bearers’), foraminifers or forams for short, are a large phylum of amoeboid protozoans (single celled) with reticulating pseudopods, fine strands of cytoplasm that branch and merge to form a dynamic net They usually produce a test (or shell) which can have one or more chambers, and are made of calcium carbonate (CaCO3
- Global cooling drove diversification and warming caused extinction . . .
Unlike Cenozoic larger benthic foraminifera, which can sometimes be studied as whole specimens from disaggregated sediment, fusulines generally require preparation by grinding and sectioning to reveal their internal morphology As such, most taxonomic studies of fusulines rely heavily on petrographic thin sections, often accompanied by
- The history of the ocean, as told by tiny beautiful fossils
Seafloor foraminifera in deep waters were badly hit, likely because high levels of CO 2 entering the ocean caused acidification that damaged their calcareous shells — such effects are the greatest at large depths But this time, few plankton species went extinct, in part because foraminifera escaped the warmth by moving to colder areas

The Foram Group exists to serve the interests of all micropalaeontologists with research and applied interests in the Foraminifera The Group co-organizes a highly successful annual spring meeting, held jointly with the TMS Nanno Group; in addition, we aim to support requests by members of the TMS for sponsorship of workshops and related events
- 变冷促繁荣，变暖致灭绝：科学家用“时间显微镜”揭示3亿年前后海洋生物的生死启示
地球正在快速变暖，但你知道吗？早在3亿多年前，类似的气候剧变就曾引发海洋生命的巨大波动。近日，南京大学沈树忠院士团队在《Science Advances》发表重磅成果，首次以高精度大数据揭示：在晚古生代（约3 4亿至2 5亿年前），地球缓慢变冷时，海洋生物加速演化、种类剧增；而一旦气候急剧变暖
