Flora
Cnidarians
Research
- Ou et al. (2017) consider early Cambrian species Galeaplumosus abilus and Chengjiangopenna wangii to be junior synonyms of Xianguangia sinica, interpret fossils attributed to members of these species as parts of the same organism and consider X. sinica to be likely stem-cnidarian.[2]
- Pseudooides prima is interpreted as a cnidarian and a senior synonym of Hexaconularia sichuanensis by Duan et al. (2017).[3]
- Fossilized cnidarian medusae are described from the Cambrian Zabriskie Quartzite (California, United States) by Sappenfield, Tarhan & Droser (2017), representing the oldest macrofossil evidence of cnidarian medusae from the Phanerozoic reported so far.[4]
- A study on the morphology of phosphatic tubes of Sphenothallus from the Early Ordovician Fenxiang Formation (China), as well as the Silurian and Early Devonian of Podolia (Ukraine), and its implications for the evolution of symmetry in the body plan of cnidarians is published by Dzik, Baliński & Sun (2017).[5]
- A study on the succession of coral assemblages through the Ordovician–Silurian transition in South China is published by Wang et al. (2017).[6]
- A study on the extant and fossil stony corals, intending to determine whether fossil corals lived in symbiosis with photosynthesizing dinoflagellates, is published by Tornabene et al. (2017).[7]

- Kaiho & Oshima (2017) calculate the amounts of stratospheric soot and sulfate formed by a virtual asteroid impact at various global locations, and conclude that the Cretaceous–Paleogene extinction event was caused by the Chicxulub impact happening at the hydrocarbon-rich, sulfate-dominated area on the Earth's surface, and that an impact at a low–medium hydrocarbon area on Earth would be unlikely to cause mass extinction.[372]
