These dinosaurs are definitely much smaller than they appear in these photographs - but they have a huge following.

They are the stars of an Instagram account called #dinodinaseries that sees them pop up in exotic - and sometimes not-so-exotic - locations around the world.

The account now has 17,000 followers, with 530 images of their exploits posted so far.

The creator of the account is photojournalist Jorge Saenz, from Paraguay.

He began taking photographs of his son's toy dinosaurs - Brontosauruses Dino and Brachy, Spiny the spinosaurus and Dina the stegosaurus - in 2013 after an image featuring one of the reptiles went viral on Instagram.
