 The study of Permian and Triassic concostricans from the baby I. Cayman section of western Siberia revealed five distinct types of ornamental patterns on their shells. These patterns included pitting, nodules, reticulation, radial leery, and radial fringe. Additionally, the researchers found that certain species transitioned between different types of ornaments over time. This suggests that these patterns may serve as a useful tool for identifying and classifying species at the genus level.
