Fossils of Peipiaosteidae \ndiscovered from Jurassic and Cretaceous deposits in \nChina provide important evidence for understanding the \nearly evolution of acipenseriform fishes. These Mesozoic \nacipenseriforms already possessed characteristic features \nsuch as an elongated snout, a heterocercal tail, and bony \nplates, sharing many morphological traits with modern \nsturgeons. The long evolutionary history of \nAcipenseriformes demonstrates the diverse ways in which \nray-finned fishes have adapted to aquatic environments.",
