The Lourinha museum is worth a visit, and you'll see detailed there many local finds, fossilised dinosaur eggs and babies. The Nest of Paimogo [Lourinha] is where carnivorous dinosaurs congregated every year to lay eggs.

From :- Walking with Dinosaurs

"The nest of a dinosaur very like Allosaurus has been found near Lourinha, Portugal. There were about 100 eggs in the nest and there may have been many more. Inside some of the eggs were tiny fossilised embryos which revealed the type of dinosaur which had laid them."

In the "New Scientist" an article from 1994 starts:-

"MORE than 200 dinosaur footprints have been discovered in a quarry near the sanctuary of Fatima in Portugal. The footprints form at least 15 tracks, two of which are more than 140 metres long. The longest track has 90 footprints. "It's as if the track were fresh - as if we just saw the animals passing," says Vanda Santos, a Portuguese palaeontologist."

Beyond the scientific, everyone seems to know where their local dinosaur footprints are. I asked a local friend and was told that on the Atlantic road from Foz to Sao Martinho there are footprints, but you will not find any signposts to this effect.

Many of the footprints are hidden from passing tourists. I'm told that the archaelogists deliberately cover them up after discovery, so as to avoid tourists taking samples and destroying the finds.
