Prehistoric humans in Brazil carved drawings in the rock next to dinosaur footprints, suggesting that they may have found them meaningful or interesting, a new study has found.

The rock carvings, which archaeologists call petroglyphs, are at a site called Serrote do Letreiro in Paraíba, an agricultural state on the eastern tip of Brazil. Researchers first observed the marks in 1975. But they are now interpreted as relating to the footprints following recent field surveys aided by drones, which uncovered previously unseen carvings. The tracks belong to dinosaurs from the Cretaceous Period, which ended 66 million years ago.

“People usually think that Indigenous people weren’t aware of their surroundings or didn’t have any kind of scientific spirit or curiosity,” said study coauthor Leonardo Troiano, an archaeologist at the Institute of National Historic and Artistic Heritage in Brasilia. “But that’s not true. It’s very clear that they were interested in the footprints. We’ll never know if they knew about dinosaurs, but it is clear that they were curious about the prints and thought they were meaningful in some way.”

The Serrote do Letreiro petroglyphs aren’t the first examples of rock art found close to dinosaur prints, but the authors of the study said they believe that the unprecedented clarity of the association between the two at this particular site could have significant implications across paleontology, archaeology and cultural heritage studies.

1. Now, some will say, see, humans coexisted with dinosaurs.

2. Some think "The Flintstones" is a documentary series. Have you

ever seen a picture of that ridiculous diarama at the "creation museum"? Tropical setting, a male and a female figure, in Victorian-style clothing, with a dinosaur next to them.

11. And then there is noah's ark in Kentucky.

Guess the dinos wouldn't fit on the ark

[niyad]

13. And isn't that at some taxpayer-funded site?

[twodogsbarking]

16. Yep.

7. 6000 years ago

[niyad]

8. Yes, thank you! I had forgotten to add that!

[PatSeg]

10. In that context, it all makes sense then!

[prodigitalson]

12. and PROOVES noah's arche!!11!

3. KNR and thank you for this fascinating find.

5. I love stuff like this!

Fascinating.

14. Actually, those are rough drafts

done by space aliens who moved on to fields after a little more practice.

15. If you track and hunt animals for dinner...

... of course you'll find these tracks interesting and inevitably have some speculations about the animals that made them.

The people I have the most difficulty understanding are the incurious -- those who wouldn't recognize the tracks in the first place or care to speculate about the animals that made them.
