2017 in paleontology
From Wikipedia the free encyclopedia

|---|---|---|---|
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils.[1] This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2017.
Flora[edit]
Cnidarians[edit]
Research[edit]
- 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]
