Nuestros colegas del MUJA acaban de publicar un nuevo trabajo en la revista Ichnos describiendo los rastros y pisadas de cocodrilomorfos del Jurásico (Kimmeridgiense) de Asturias. La costa asturiana es bien conocida por su registro en icnitas de dinosaurios, sin embargo también conserva interesantes icnitas de tortugas, pterosaurios y cocodrilos
El resumen es el siguiente:
Some small and medium-sized crocodylomorph footprints are described from the Late Jurassic (Kimmeridgian) coastal and
deltaic units of the northern Spain (Asturias). There are at least four footprint morphotypes. Three of them, with well preserved trackways, are included in the ichnogenus Crocodylopodus (Crocodylopodus isp. and Crocodylopodus meijidei); the fourth one, documented by some isolated large footprints, is referable to the ichnogenus Hatcherichnus. This ichnoassociation confirms the presence of small crocodilians in palaeoenvironments apparently dominated by dinosaurs. The presence of Hatcherichnus seems to confirm the affinity between the Iberian and North American ichnofaunas.
