By detecting and studying La Binh fossil fish (fish that live in La Binh, Van Nam, China rivers) dating back to 244 million years, Chinese researchers have created a breakthrough in the process. Early life evolution of subspecies of whole bones. This breakthrough opens important evolutionary sequences to the skull of all-bone fish, thereby helping to reconstruct the evolutionary scheme in the most complete way. Research conducted by Xu Guanghui, the Institute of Ancient Biology of the Chinese Academy of Sciences.

Fossil fish La Binh is relatively rare in the evolutionary history of all-bone fish , but it is unclear which fossil belongs to which fish. Therefore, researcher Xu Guanghui collated the skull shape of nine samples of La Binh fossil fish with different species of fossils and came to the conclusion that the La Binh fish fossil is representative of the patent fish.

Xu Guanghui said that the subspecies of the whole bones are divided into 2, including the finfish and the patent fish . Because of the subspecies of the whole fish bone and the subclass of true bone fish, there is a close relationship with each other, so the subspecies of whole bones have a key role in studying the new class of finfish and the class of fin rays (belonging to real bone fish.

La Binh fish is the largest full-bone fish in the fish population in Van Nam with a total length of 40cm. This fish was found in the Triassic sea stratigraphy from 244 million years ago and has been proven by potential researchers to reconstruct the marine vertebrate ecosystem.
