Lovely idea. Btw, dinosaurs became big globally because of the movie Jurassic Park. Single biggest reason they entered kids’ minds. That’s the power of a great movie (and a great novel).
But you do a disservice to grandmas. Don’t you know that the Nagas and great mythological serpents were dinosaurs? And Vanaras were intelligent apes? Evolution confirms this!
Oh, and NASA has declared Indian mythology the most scientific in the world.
