Produced by Happy Kin Toys/Lontic/Tedco and sold under various brand names (most often seen under the "Kid Galaxy" banner) by various manufacturers, these articulated dinosaurs/animals/sea life are great, inexpensive toys.
I first noticed them while doing site coverage of Toy Fair a few years back but only started seeing them pop up in brick and mortar stores 2 years ago, most often showing up at close out/discount stores like TJMaxx and Marshalls. These toys are often found at gift shops in museums, aquariums and zoos. They are also available from several online retailers like Amazon, Walmart and Pure Fun Supply as well as direct from Tedco.
The most often encountered sets are various 3pks, but they can also be found single boxed or in larger sets ranging anywhere from 4 to 12 animals/dinosaurs/sea life in a box.
The plastic quality is decent, thinner than Chap Mei, but better than the cheap Chap Mei knock-offs that pop up every holiday season. The paint apps are often crisp and clean aside from some occasional sloppy apps on the teeth and eyes.
Many of their early dinosaurs are bootlegs of old Hasbro "Jurassic World III" figures (easily identified by their painted over but still part of the sculpt wounds), but later figures were original sculpts. All of their animals and sea life figures are original sculpts.
They also produce static vinyl dinosaur figurines in 2 sizes representing the species from the articulated line (in matching or complimentary color schemes) as well as species that have not yet been released in the articulated line, possinly hinting at future releases.
Some examples of the articulated sets available via Amazon:
