I'm guessing dinos are pulp (I'll put a link on VSF just in case). This tub of dinosaurs is from Poundstretcher in the UK and cost £2.99. I got a tub for my dino-mad grandson then decided to get one for me as well - you never know when you may need some, after all...
Here's the set with a 25mm figure in there for scale. As well as the dinos, there's a vac-formed hill/mound (flimsy), two trees and two things that look like mounds of dino poo but possibly are just meant to be rocks.
Here's a different view:
Six dinos in all, if you include the pterodactyl.
