      The tricky thing about dinosaur footprints is that unless you find the fossil of the dinosaur that made it right next to it it can be quite hard to know.

      However, this one was found in Cretaceous rocks, this is quite long after dinosaurs first evolved, so lots of the big ones like diplodocus had already gone extinct. It’s also in Bolivia, and definitely from a Sauropod dinosaur so we have to think of species of sauropod dinosaurs that were still not extinct and lived in what is now Bolivia.

      There was one group of dinosaurs big enough to make this kind of footprint left living there called the Titanosaurs. This included things like Argentinosaurus and Almosaurus, So they aren’t sure what the name of the dinosaur that made this was, but it was probably one of those.

      I saw this in Toro Toro national park, there are hundreds of dinosaur footprints there it’s really awesome, there is even one where you can see that when the dinosaur stepped in the mud it squished up between his toes! And one where you can see a mum dinosaur’s footprints next to a baby dinosaurs footprints.
