Originally released in 1955 as part of Marx’s Medium Mold Group, PL-750, today we’re looking at the Marx Allosaurus. This group of toys included the Allosaurus, Ankylosaurus, Hadrosaurus, Pteranodon, Stegosaurus, and Trachodon and was Marx’s second set of dinosaur toys. In 1959 the Marx Allosaurus would be re-released as part of their Revised Mold Group.
Brand: Marx
Ankylosaurus (Marx)

No collection of toy dinosaurs would be complete without the “great fused lizard”, Ankylosaurus magniventris, and it has been that way since 1955 with the release of the first dinosaur toys ever mass produced, by Marx. The Marx Ankylosaurus was included in Marx’s second wave of dinosaur toys, known as Medium Mold Group, PL-750.
Brontosaurus (Marx)

Before we begin the review, I would like to take a brief aside and recollect for a moment, as the date of this posting has some significance to me personally. Today, July 16th, 2021, is my 10-year anniversary writing for the Dinosaur Toy Blog. It was on this day in 2011 that my first review was posted here, the AAA woolly rhinoceros.
Dimetrodon (Marx)

This review marks a somewhat significant milestone on the blog with regards to Marx reviews. This is the last review for the toys released under the small mold group, PL-755; they’ve now all been covered here. There are still plenty of Marx toys left to write about but for this group in particular, we’re done!
Hadrosaurus (Marx)

Although we are all familiar with the dinosaur family hadrosauridae it seems that the dinosaur that gave the family its name has been largely forgotten, despite being a historically important dinosaur. Hadrosaurus foulkii was first described by Joseph Leidy in 1858, from remains found in New Jersey’s Woodbury Formation.
Iguanodon (Marx)
Megatherium (Marx)

Before we begin with the review, I want to ruminate on some things, because this review is significant in a couple of ways. For one, it’s my 200th review for the Dinosaur Toy Blog. I’ve known it was coming for some time now and over the course of several months deliberated over which figure should be selected for the occasion.
Moschops, Sphenacodon, Cynognathus (Marx)

Given that I counted correctly, this here will be my 50th review for the DTB. On the search for a worthy entry for that occasion, I deceided to add some figures to my collection that will provide the chance to combine the jubilee with a premiere cause to my big surprise I found that the American company Marx, despite its significance for our hobby, has not a single entry on the blog as of yet….
Parasaurolophus (Marx)

Carrying on with our series of Marx reviews next up is that most popular of ornithopods, Parasaurolophus. Like the previously reviewed Styracosaurus this figure is part of the Second Series Mold Group, PL-1083. This mold group was the most recent and last from Marx, produced in 1961. I’m hard pressed to think of a Parasaurolophus toy that’s older than this, which makes it the first ever, and I find that significant.
Plateosaurus (Marx)

When I originally started reviewing Marx toys I only had four lined up for review but between then and now I’ve collected a few more which will extend my Marx series for the next few reviews. Up until now all of the toys I reviewed were from Marx’s 1961 second series mold group, PL-1083.
Pteranodon (Marx)
Smilodon (Marx)

In addition to a diverse assortment of dinosaurs Marx also produced quite a few other prehistoric animals. Some, like the Dimetrodon and Pteranodon were obvious additions to the line; others like the Cynognathus are more surprising additions. Marx also produced three Pleistocene mammals (not counting the cave men) and you could probably guess what at least two of them were.
Stegosaurus (Marx)

The Marx Stegosaurus was first released in 1955 as part of Marx’s second wave of dinosaur toys, known as the Medium Mold Group, PL-750. The Marx Stegosaurus is based on the Stegosaurus painted by Rudolph Zallinger in his Age of Reptiles mural at the Yale Peabody Museum. So similar are they that the Marx toy even has an oddly placed forelimb just like on the painting.
Styracosaurus (Marx)

It’s no secret, finding subjects to review for the DTB has become somewhat of a challenge over the last several years. Nearly every figure by all the major players has been reviewed or has a review in the works; Safari Ltd., Carnegie, Papo, CollectA, PNSO, Battat, Invicta, Tyco, and the list goes on.
Trachodon (Edmontosaurus) (Marx)

Trachodon is, or was, a genus of hadrosaurid described by Leidy in 1856 for which the only material known was a mix of teeth from both hadrosaurids and ceratopsians. That’s not much to go by and Trachodon is now considered nomen dubium. During its day however, Trachodon was a household name and the classic “duck-billed” dinosaur of pop culture.
