Extinct Monsters! Part II

In my last post I introduced the Marx dinosaurs from the 1950s and 60s. The set I own is the earliest - Series 500 from 1957. It has the following Extinct Monsters: 

Allosaurus	dinosaur	gray - toe out
Ankylosaurus	dinosaur	gray - fat legs + circle
Brontosaurus	dinosaur	brown - large circle
Hadrosaurus	dinosaur	gray
Plateosaurus	dinosaur	green - description  closer
Stegosaurus	dinosaur	gray - large circle
T. Rex	dinosaur	brown - fat
Trachodon	dinosaur	gray - hand down
Triceratops	dinosaur	green - thick horns
Kronosaurus	reptile	silver gray
Pterandon	reptile	gray
Dimetrodon	synapsid	green - mold circle
Sphenacoden	synapsid	green
Cynognathus	therapsid	green

So nine dinosaurs, two reptiles, two synapsids and one therapsid for a total of fourteen. The descriptions identify these as from the earliest molds. Later molds have subtle differences.

Here are two more comparisons with the Papo versions.
