Artist's impression showing one eagle shark. Oscar Sanisidro - The fossil of an unusual shark specimen reminiscent of manta rays sheds light on morphological diversity in Cretaceous sharks. This plankton feeder was discovered in Mexico and analysed by an international team of palaeontologists led by a CNRS researcher from Géosciences Rennes 1 (CNRS/University of Rennes 1). The study was the lead in Science on 19 March 2021. The Rennes Geosciences laboratory is a member of Observatoire des sciences de l'Univers de Rennes (CNRS/Université de Rennes 1/Université Rennes 2/INRAE/Institut Agro) - 93 million years ago, bizarre, winged sharks swam in the waters of the Gulf of Mexico. This newly described fossil species, called Aquilolamna milarcae , has allowed its discoverers to erect a new family. Like manta rays, these 'eagle sharks' are characterised by extremely long and thin pectoral fins reminiscent of wings.
