During the IXth Symposium on the Iberian Atlantic Margin held last week in Coimbra (Portugal), I made a short trip to Cascais to the west of Lisbon where I noticed a fossil-rich pavement along the corniche to Estoril. The surroundings are Cretaceous outcrops according to the maps but it is not sure that the pavement was extracted from them. What are these magnificent fossils?
