Paleontology
editFossil remains of Triassic tetrapods are known in the river basin. The first location of fossils was discovered in 1951 opposite the village of Goryainovka, on the right bank of the Chapayevka. Bones of unidentified labyrinthodonts were found in conglomerate outcrops. In subsequent decades, other fossil sites were discovered in this region.[2]
In the summer of 2020, in the ravine, which flows into Chapayevka 0.8 km northeast of Orekhovka village, another location of Early Triassic fossils was discovered, composed of clays, bone-bearing sandstones and conglomerates. Early Olenekian temnospondyls are known from this locality. Occipital parts of the skulls and the right part of the lower jaw of Benthosuchus sushkini, the right part of the lower jaw of Thoosuchus sp. and fragments of jaws and ribs of unidentified amphibians were collected from these deposits.[2]
