It’s a sunny day at the beach in Parede, on the Lisbon coast. Families have set up beach chairs and towels on the sand. Children are playing in the small puddles in the beach rocks. Some splash at the water in a series of nearly circular bowls, 50cm across. Few of them, if any, realize that what they are playing in are the traces of a dinosaur which came walking through shallow water 100 million years ago, leaving footprints in the mud that have become preserved even to the present day.
These prints were really only identified by paleontologist Dr Vanda Faria dos Santos in 2011. She has recommended that these tracks be designated as a Natural Monument, allowing for protection, but so far nothing has happened.
Dr Santos explains that the tracks clearly show a trail, the tracks in a row showing left and right feet. She says that it’s not certain what species produced the tracks, but they are definitely sauropods. The prints date back 100 million years, to the late Albian stage of the Cretaceous Period.
With further study, it’s clear that there are at least two trails of sauropod tracks, by two individuals. There are many other prints visible, although they are not clearly defined. The sediment in which they were made was fairly course, and the various prints, made at different times, have tended to obscure each other. (No doubt the aeons of weathering have had an impact, too!)
The tracks are not always visible. As one might expect, at high tide they are covered by the sea. However, even at low tide they might not be visible. The sand shifts based on tides and ocean currents and at some times the tracks are completely covered by sand.
Updated August 2024: The municipality has put up a large mural depicting many dinosaurs that have been found in Portugal, and have put up a detailed noticeboard with loads of information about the site and the footprints. There’s also an augmented reality website (link below).
Looking at the beach in the summer, there are plenty of people enjoying the beach, but even with a seriously low tide, the sand can still cover the footprints! In the photos below, the fossilized footprints are circled in red.
Location
Parede is a town along the Lisbon coast, between Lisbon and Cascais. It’s in the municipality of Cascais, Lisbon district. The beach is on the waterfront, along the Marginal (N6) road.
Access
Parede Beach is easy to get to, with ample parking. The walkway just above the beach passes right by the footprints, which are right in front of Bar Xana. There is a ramp that reaches the beach very near the footprints, and a staircase a little further on.
Signage
There is a signboard with loads of information on the walkway over the beach:
