The stamps were issued (die–cut/self–adhesive) in 2 booklets of 6 stamps (6 x 1.20 & 6 x 2.50), as miniaturesheet (perforated/water-activated) and imprinted on a set of five stationery postal cards.
According CTV News Calgary (July 8, 2015), "Canada Post is recalling all stamps commemorating Dinosaur Provincial Park, issued to post offices last week, because the hoodoos on the stamp don't exist there but are actually from east of Drumheller, Alberta".
"Officials at Canada Post have issued a recall on a stamp featuring Dinosaur Provincial Park, a UNESCO World Heritage Site, because of a big problem. The error comes from the image used on the stamp, which is of a set of hoodoos, a rock formation found in the provincial park, located just north of Brooks, Alberta. The problem is that the image on the stamp is actually of hoodoos that exist east of Drumheller, a community about an hour and a half northwest of Brooks. Canada Post has apologized for the error and is recalling the stamps from all post offices so they can be destroyed. A new stamp, with a correct picture, will be released at a later date (text: CTV News website)".
The Dinosaur stamps are no longer available in the online shop of Canada Post and Post offices, but there are number of erroneous Dinosaur Park stamps in circulation. Canada Post stopped selling the Dinosaur stamps, after preorders were already shipped.
