Kaiyodo's DINOLAND series is an outstanding collection of scale model dinosaurs. Dating from the mid-1990's, it included a number of full skeleton reconstructions. The skeletons were superbly detailed and, especially for the time, extremely accurate. Even complex elements such as the gastralia (belly ribs) were modeled. As a series they have never been equaled.

Despite the importance and technical merit of the skeleton models, researching them has been a challenge. One of the important questions for me was the identity of the artist or artists involved.

Interestingly, all the Kaiyodo osteological models were the work of one man; Shigeru Yamazaki. He's credited on the Futabasaurus and Velociraptor skull documentation but not on other kits I have. I find no mention of him searching the web, which is surprising since other Kaiyodo artists are easy to find.


Kaiyodo is a Japanese company many dino fans will know of, especially after the success of the Dinomania line of miniature dinosaur and prehistoric creatures. But Kaiyodo can be frustrating for anyone outside Japan; their web site is entirely in Japanese and impenetrable to a non-Japanese reader like myself. Even their most successful dinosaur product, the Dinomania series, is not sold through regular channels, so don't look for them in your local store! That said, they have produced a huge range of outstanding models over the years as any web search will quickly discover. Kaiyodo built their reputation with high-quality garage kit models and early kits, such as those described here, were all hand cast from silicon molds. This "garage" production technique is labor intensive and few were made. They were also expensive.


This page summarizes what I know about Kaiyodo's DINOLAND skeleton model kits. Much information is still missing. If you can help me update this resource with further material I am very keen to hear from you. Please contact me.

Possibly Shigeru's first skeleton model,
it was likley a commissioned work. The
