The very first illustration of Hypsilophodon that I ever laid eyes on depicted it as a very lizard-like animal perched high on a tree branch, an erroneous notion that arose back in 1912 and persisted until 1971 when it was finally debunked—although that didn’t stop children’s dinosaur books from continuing to portray Hypsilophodon as arboreal until well into the 1980s.

Review: Jakapil (Jurassic World: Chaos Theory, Danger Pack by Mattel)
2.8 (4 votes)
Jakapil is a genus of basal thyreophoran discovered in the Candeleros Formation of Argentina and described in 2022, it is also one of the coolest dino-discoveries in recent years, although I might be biased since I have a thing for basal thyreophorans.
Review: Lophostropheus (Jurassic World: Chaos Theory, Danger Pack by Mattel)
3.6 (5 votes)
Lophostropheus is a coelophysoid theropod known from the boundary between the late Triassic and early Jurassic. It is known from a single tooth, a handful of vertebrae from the neck, back, and tail, some pelvic material, and an unidentified fragment. Such scant remains practically guaranteed a toy of Lophostropheus from Mattel, and here we are.

Mapusaurus is a carcharodontosaurid that lived in Argentina during the late Cretaceous and is also one of the largest theropods known. It was only slightly smaller than its close relative, Giganotosaurus, and the skeletal differences between them are minimal.
Review: Guanlong vs. Lystrosaurus (Jurassic World: Chaos Theory, Epic Evolution Danger Pack by Mattel)

Recently, Mattel has started dabbling with small-figure two packs, first with an Eoraptor vs. Stegouros pairing and then with the set we’re looking at today, Guanlong vs. Lystrosaurus. I think these two packs are a fantastic idea and hope that Mattel will produce more of them in the future.
Review: Rauisuchus (Jurassic World: Chaos Theory, Epic Evolution Danger Pack by Mattel)
4.2 (18 votes)
Rauisuchus is a genus of pseudosuchian that lived in the late Triassic of what is now Brazil. It is also the latest pseudosuchian and Triassic taxa offered from Mattel, who has miraculously produced more of these animals than any other toy company I can think of.
Review: Becklespinax (Altispinax) (Jurassic World: Chaos Theory, Epic Evolution Battle Roarin’ by Mattel)
4.5 (32 votes)
Leave it to the Jurassic World franchise to once again thrust an exceptionally fragmentary dinosaur into the limelight and give it the wrong name in the process. Becklespinax is one of many synonyms for the early Cretaceous English theropod now known as Altispinax.
Review: Monolophosaurus (Jurassic World: Chaos Theory, Epic Evolution Strike Attack by Mattel)
3.2 (27 votes)
Even before Monolophosaurus was featured in Camp Cretaceous, Mattel was making toys of them and they started pumping them out with the first wave of Jurassic World toys in 2018. Since then, they’ve produced at least nine of them, maybe more.
Review: Pachyrhinosaurus (Jurassic World: Chaos Theory Wild Roar, Epic Evolution by Mattel)

There is no shortage of Pachyrhinosaurus toys. As ceratopsian toys go it is only outnumbered by Triceratops and Styracosaurus, which have been more popular for far longer than Pachyrhinosaurus. But here’s the thing, all those Pachyrhinosaurus toys represent the same species, P.
