A cave is a good place for newly hatched dinosaurs to hide from large predators. But the great dinosaurs knew this and waited for their pray outside the cave.
Many creatures hid from the large carnivorous dinosaurs in caves.A cave was of interest to all dinosaurs. If the cave was big enough, it was a good place to hide from enemies. The predatory dinosaurs of course knew this and looked for prey there. A Quetzalcoatlus circles above the cave and waits for an incautious young animal that it can sweep down on. A Carnotosaurus is also waiting for the right moment to strike. Watch out, little dinosaur, that none of the robbers get you.
