Marx Dinosaurs and Prehistoric
Marx produced series of dinosaurs and prehistoric creatures in soft plastic beginning in the 1950s.
The main series started with three molds in 1955, numbers PL-749, PL-750, and PL-755. There was a later revision of the primary group with mold PL-977, and new additions later with mold PL-1083. Earlier dinosaurs are in soft plastic most commonly grey and green, with some brown or tan. Later ones are in a more waxy feeling soft plastic in similar colors, and the last ones were in other colors with blue and yellow being the more commonly seen. Many of the dinos have been reissued by other manufacturers using the same molds, and copied by many more. The original series was produced in very limited quantities out of hard plastic and painted, to be used as a giveaway at the Nuremberg Toy Fair.
The first mold PL-749 contained three large animals
PL-750 had six medium sized animals
- Marx Allosaurus - right foot has a larger outside toe pointing more outwards
- Marx Ankylosaurus - has one large injection mold circle and a pebbly looking belly
- Marx Hadrosaurus
- Marx Pteranodon
- Marx Stegosaurus - has one large injection circle and 3 smaller ones
- Marx Trachodon - right arm points down
PL-755 made five small animals
- Marx Cynognathus
- Marx Dimetrodon - has mold injection circle on stomoach
- Marx Plateosaurus
- Marx Sphenacodon
- Marx Triceratops - has thicker horns
PL-760 and PL-761 are numbers for plants and their bases respectively.
- Marx Large Palm Tree
- Marx Large Double Palm Tree
- Marx Small Double Palm Tree
- Marx Fern with 3 Fronds
- Marx Fern with 4 Fronds
- Marx Dead Tree
In 1959 a revised mold PL-977 was made combining together and remaking many of the animals. Most look nearly identical, but the Tyrannosaurus Rex was completely new.
- Marx Allosaurus 2 - right foot has smaller outside toe and all point forwards
- Marx Ankylosaurus 2 - has no injection circle and lines on belly
- Marx Brontosaurus 2 - looks the same as the first but has smaller mold injection circles on the feet
- Marx Dimetrodon 2 - no mold injection circle
- Marx Stegosaurus 2 - has all small injection circles
- Marx Trachodon 2 - right arm points up
- Marx Triceratops 2 - has thinner horns
- Marx Tyrannosaurus Rex 2 - known as the skinny T Rex
In 1961 a new mold was made PL-1083 with eight new creatures.
- Marx Iguanodon
- Marx Mammoth
- Marx Megatherium
- Marx Moschops
- Marx Parasaurolophus
- Marx Smilodon
- Marx Struthiomimus
- Marx Styracosaurus
The Flintstones Playset included dinosaurs from the main line plus various character figures, only two of which were animals. These have both been reissued over the years.
There was also the Flintstones Hunting Party set. This also included dinos from the main line, plus three very large hollow ones made using two parts glued together. These are rare and tend to be pretty expensive, they have never been reissued.
As part of the Tinykins line there was also the two pets, in small hard plastic and factory painted
These were small versions of some of the main line dinos produced of hard plastic and sold in individual boxes. Made in Hong Kong and marked as ELM - Empire Louis Marx.
These are small metal dinos made as part of the Elegant Miniatures line produced in Japan
