Monumento Natural das Pegadas dos Dinossáurios


On the N357 and 10km south of Fátima (the pilgramage destination) in the village of Bairro there is an ex-quarry with more than a thousand dinosaurus footprints. Among them sauropod tracks estimated at 175 million years old.


The picture top, left tells the story how the tracks were made and how come they are still there.


  1. The area was once somewhat flat with many shallow pools, with carbonated sediment at the bottom. Dinsosaurs walked all over the area, including stepping into the pools.
  2. The second diagram shows the track left in the sediment.
  3. Diagram three shows the forming of limestone, keeping the track intact. Fossilising.
  4. The fourth diagram shows the scew lift of the fossilised bottom as earth pressures formed the Serra d’Aire (Aire mountains).
  5. The last picture shows quarying for limestone, that finally uncovered the hard bottom.

The picture bottom left shows the remains of the quarry and the incline, that was laid bare.


The two pictures on the right shows two sets of tracks, that are now visible. A roped walkway makes it possible to view the tracks, while discouraging people to step on them.

Those Dinossáurios didn't heed rope lines, Louis!
Louis: No, they didn't, Ray - but they did direct where humans would walk many years later.
Fascinating, Louis, there are places like this around here.
Louis: Kind of stuff I am interested in - the archaeological part of history.
this is really cool...
Louis: I thought so, too, Larry.
A fascinating post, Louis! As Frank says - we have dino tracks here, and even more in Wyoming where I grew up. An endless source of interest to me!
Louis: Thank you Elizabeth. You sure they are not Big Foot tracks? ;-)

I can't really imagine something being in place for175 million years Louis, it's just mind blowing
Louis: They test, based on a theory, extrapolate and add some algorithms to provide for a theory of existence. So the numbers may be shorter ... or longer smile But some beast did walk around there long ago and it remains fascinating.

I had no idea there were so many dinosaur tracks to be seen anywhere
Louis: Fascinating place to visit, if you happen to be in the area and are interested in archaeology.
LOL at Lisl, but she's right. We're still so curious, aren't we!
Louis: Good thing we are curious, otherwise airports would not be required.
There is something amazing about seeing dinosaur prints
Louis: I agree, so I don't mind having spent some time to find the place. The only sign is directly at the entrance.

A fine educational display Louis. I would love to see these and heaven forbid anyone from walking on the footprints.
Louis: Thank you gutteridge. Although the rock quite hard, the surface did break at places due to plant roots and rain.
I really would like to see this for real. I spent most of my working life in the offices of one of our major quarrying companies and from time to time fossils of interest would be discovered and put on show in the reception area of the building.
Louis: The quarrying operation has moved to some nearby site, where I blundered into, searching for the site of the dino tracks. The 'new' site also looks fascinating, but from a mining/geological perspective. They even offered me a tour - friendly people.
I have great interest in this type of place.
Louis: Archaeology fascinates me too, Mary.

Isn't this just mind blowing, Louis. And to think of it that 'we' will not live another 175 million years.... the end is near, my fiend. (not tomorrow, but we cannot say that we are kind to this world)
Louis: No, we are not kind to this world, indeed. The tracks are of animals that are extinct - just to bring a point home ...
If I'd known it was so close to Fatima, I'd have gone there on my 2016 trip to Portugal!
Louis: It would have been worth your while, Tom. Well, I enjoyed it.
the dinosaur walk of fame, Louis. thank you for sharing with us. i cannot imagine 175 million years - but then again, this is called the age of instant gratification!
Louis: Walk of fame ... heh, nice expression, thanks Ayush.
this was very informative Louis... it's amazing that we can look and the footprints of dinosaurus after 175 million years... very good presentation....petersmile
Louis: Thank you, peter. It is amazing that we are afforded that view.
