This set comprises 9 large dinosaurs, 4 medium size, 4 small dinosaurs, three trees, 2 fences and one egg. My nephew was delighted with them and will no doubt spend hours playing with them. They include a good range of dinosaurs including, a stegosaurus, pterodactyl, spinosaurus, t rex and many others. Unfortunately one of the larger dinosaurs didn't stand up but this did not detract from the enjoyment as he was the one been eaten by the others.
One thing I would say is that it it advisable to take them out of the box and leave them out for a few days before you give them to your child as they do smell quite a bit initially.
A great set for several children to play with at one time.
