First record of a hybodont shark (Chondrichthyes: Hybodontiformes): from the Lower Cretaceous of Colombia

The Mesozoic chondrichthyan fossil record from northern South America is scarce and poorly known containing only a few reports of lamniform and ptychodont species from the Upper Cretaceous of Colombia and Venezuela. Here, we report the discovery of two associated (found together) dorsal fin spines o...
