Similarity between Gorjanovicia and Sauvagesia: ecophenotypy, polimorphism, or hybridisation? (Santonian, southern Istria, Croatia)

Fossil rudists Gorjanovicia and Sauvagesia are identified from the Santonian of the southern Istria locality. Some Sauvagesia specimens have shapes and ornamentation that are morphological intermediate between Gorjanovicia and Sauvagesia. This example highlights the need to consider morphological variations impact at our interpretation of the fossil record.
