On October 26th, researcher Xu Guanghui from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences was interviewed in Beijing to introduce his latest scientific research results-the discovery of the world’s oldest known wartodon fish in Luoping, Yunnan Fossil, named "Yunnan Storm Fish".
With a body length of 34 cm, it is the largest known carnivorous basic neofin fish in the Luoping biota 244 million years ago (Middle Triassic Anni), occupying a higher position in the food chain.
The discovery and research of "Yunnan Stormfish" updated people's understanding of the food chain network structure of the Luoping Biota and Triassic biological recovery, and further indicated that a mature and complex food chain network had been established in the early Middle Triassic.
This important paper in the field of paleontological evolution has been published in the latest issue of the international academic journal PeerJ.
Xu Guanghui said that the wartyfish family was the largest carnivorous basic neofin fish in the Triassic. The newly discovered "Yunnan stormfish" is a close relative of the wartyfish. It is currently only found in Luoping, Yunnan and represents the wart. The oldest genus and species of the tooth fish family.
Compared with the warty tooth fish, the upper and lower mouth margin teeth of the "Yunnan storm fish" are stronger and stronger, showing stronger predation ability.
He said that with the discovery of the "Yunnan storm fish" as an opportunity, the latest study included the Phytodontidae in the clade system study for the first time, reconstructing the branch evolutionary tree of the early neofin fish, which is useful for understanding the early neofin fish. The phylogenetic relationship, radiation evolution and ecological adaptation of the main taxa are of great significance.
