BITE MARKS ON THE VERTEBRA OF LEVNESOVIA TRANSOXIANA (HADROSAUROIDEA), AS EVIDENCE OF THE CARRION-EATING BEHAVIOR OF TIMURLENGIA EROTICA (TYRANNOSAUROIDEA)

Chudakova Sofya Egorovna

A comprehensive and in-depth study of the remains of organisms of the geological past includes the study of the relationship of extinct organisms among themselves and with their habitat, is of paramount importance for the theory of biology, since the problem of the evolution of the organic world and the origin of adaptations require a deep understanding of the processes of formation under the influence of external and internal factors. Bites (traces of food) on the bones of prehistoric animals left by predators or scavengers have been repeatedly noted and studied by paleontologists. Here I describe the nutrition traces belonging to Timurlengia erotica on the dorsal vertebra of Levnesovia transoxiana (DIN 20/11). The size and morphological characteristics of bite marks, as well as the distance between them, were compared with the distances between teeth in the reconstruction of the upper jaw (ZIN PH 676/16) and with the sizes of isolated teeth of Timurlengia euotica. These comparisons show good correspondence and ratios.
