Occurrence of fossils in Portugal
It is very evident in almost all regions, particularly along the coast. Unfortunately, many of the best fossiliferous outcrops are becoming each time fewer accessible to collect the fossils. Some, have simply disappeared...
Urban sprawl has contributed much to this, particularly along the coast and peripheries of major cities. The negligence of non-preservation of these areas, is another of the serious problems that has also contributed much to its gradual disappearance. The rapid erosion of the fossil cliffs in some coast cliffs, due to increasingly adverse weather conditions, has systematically aggravated this loss of definitive form, the fragile and irreplaceable paleontological heritage.
It is increasingly difficult to find good examples of fossil species, in Portugal. Many species, have become almost impossible to collect again. Currently many of them, are only possible to see in older private collections, or in museums...
Fossils of Portugal
After Malacology, came also the passion for Paleontology. At the moment my collection is composed by many and rare fossils of Portugal, caught and prepared by me.
Over morer 20 years, I was joining an extraordinary paleontological collection of the periods (Jurassic, Cretaceous and Tertiary), in particular from the Upper Jurassic and the Miocene. Some of these rare fossils, are counted very rare fossils of dinosaurs and beautiful and rare sea urchins, among many others...
At the moment, I became expert in Dinosaur fossils, of the Upper Jurassic period.
Jurassic of Portugal
"Abstract - The Lourinhã and Alcobaça formations (in Portugal), Morrison Formation (in North America) and Tendaguru Beds (in Tanzania) are compared. These three Late Jurassic areas, dated as Kimmeridgian to Tithonian ar similar paleoenvironmentally and faunally. Four dinosaur genera are shared between Portugal and the Morrison (Allosaurus, Torvosaurus, Ceratosaurus and Apatosaurus), as well as all non-avian dinosaur families. Episodic dispersal occurred until at least the Late Jurassic. The Portuguese dinosaurs did not developed dwarfism and are as large as Morrison and Tendaguru dinosaurs."
