Found these cool "Jurassic World: Micro Collection" figures at Dollar Tree during my wanderings today.
They are actually made by Mattel, so they can be considered part of the official action figure line.
The scaling and details on the 2 theropods (Blue and T-Rex) and the Triceratops work quite well for juveniles. The Dimetrodon (odd choice for inclusion in such a small line as no living Dimetrodon has appeared in the films, the only one in any of the 5 films was a statue in the mansion in "Fallen Kingdom") has a really odd, shortened anatomy making it look like a "Dungeons & Dragons" miniature from the 70's- which is oddly endearing to me.
