"Each one is laser cut out of oak tag board using a 35 watt cutting laser, and pre-perfed for (relatively) easy assembly - assuming you've got some really steady hands.
"The T-Rex, triceraptops, stegosaurus and woolly mammoth kits are all available over at Kelly's Etsy shop, the Maker's Market, or Everything Tiny and cost just $7 (USD) unassembled, and $16 with a pair of tweezers and glue in a handy gift tin."
Note: If you're a complete lazy-ass with no hand-eye coordination Kelly is also selling pre-assembled dinos in a little glass case for $60. I don't recommend those. You get no street-cred for buying things preassembled.
