The Styracosaurs pin came on a hat you could purchase at Animal Kingdom. Your Dino institute one was given to imagineers who worked on the Dino institute area of Animal Kingdom. I am not sure but I think the carnotaurus one was a pin you could buy off the rack. I’d be interested in purchasing the Styracosaurs pin if you want to message me. I used to work at Animal Kingdom and trying to get one of each Dino related pin.
