It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The article describes six ichthyosaur vertebrae from the Middle Volgian substage of the Upper Jurassic of the Middle Volga region (Tatarstan). The assignment of the new find to the recently described species Kazakhstanosaurus efimovi Akhmedenov et Yakupova from coeval deposits of the Ulyanovsk region (Gorodishche section) is based on the similar structure of the cervical and caudal vertebrae, the ratio of the sizes of the vertebrae and costal facets.
