Russian archaeologists discovered ichthyosaur fossils. According to Russian News Agency 20, a representative of the Primorsky Krai Aquarium in Russia said that a group of biology students discovered two ichthyosaur fossils on the coast of an island in Vladivostok. A fragment of an ichthyosaur rib from 230 to 240 million years ago.
According to the representative, the two ichthyosaur bones have been transported to the aquarium and placed in the technical room for further processing. Due to its fragility, it is not currently on display. This is the third time ichthyosaur bones have been found on a Russian island. The ichthyosaur is an extinct marine reptile whose appearance is similar to that of a dolphin. The first discovery of ichthyosaur remains on a Russian island was in 2014. In 2020, ichthyosaur bones were discovered again on a Russian island, and it was initially determined that it lived about 1.247 billion years ago. The discoverer, a seven-year-old boy, was walking on the island when he found a stone slab cracked by a typhoon, with imprints of ichthyosaur ribs and bone fragments on it.
In the age of dinosaurs, ichthyosaurs were carnivorous reptiles living in the ocean. After they land on land and become terrestrial reptiles, they occasionally return to the water. This ichthyosaur fossil belongs to Chaohusaurus . Unlike the ichthyosaurs that appeared later, Chaohusaurus did not have a dolphin-like shape, and they looked more like lizards. This ichthyosaur did have flippers rather than webbed feet, but its neck was quite long. Chaohulong has no dorsal fin and its tail fin is short and wide. One of the smallest ichthyosaurs, less than 6 feet (1.83 meters) long and weighing about 10 kilograms
