As any kid with a dinosaur book will tell you, Mamenchisaurus is best known for having an extraordinarily long neck, making up half of the animal’s overall length.

Review: Apatosaurus (Bullyland Micro Tiere)

By now most of you should know my preference for sometimes strange dinosaur models, alleged outsiders, often being sadly overlooked.
I would like to introduce to you the Bullyland “Micro Tiere” Apatosaurus. I don´t exactly know about the release date, even Randy Knoll´s site doesn´t give any information.

Review: Brontosaurus (Marolin / VEB Plaho)

A firm from the German Democratic Republic, VEB (Volkseigener Betrieb) Plaho, released a series of highly collectable dinosaur figures in 1967. They were sold in the Museum of Sena in Thuringia, Germany until the mid-1980s. The follower firm to Plaho, Marolin, re-released them in 1990.
Review: Agustinia (Deluxe Collection, CollectA)

CollectA/Procon is somewhat unique among dinosaur toy companies in that they have an extensive range of dinosaur toys which represent relatively obscure dinosaurs. While these toys seem to vary in quality (to say the least), they at least deserve points for trying.

Review and photos by Dr Andre Mursch (“Brontodocus”). Edited by Plesiosauria.
Get your fore feet back down to earth, Bronto, here comes 2010’s latest release of the Wild Safari Dinos series by Safari Ltd:

Review: Seismosaurus (Kabaya)
Review: Camarasaurus (Dinotales Series 7, by Kaiyodo)

Camarasaurus was the most common sauropod in the Morrison Formation, which is mainly distributed in present day Colorado, Wyoming, and Utah. Many different fossils have been found, including some complete and even fully articulated specimens, so it is surprising that this dinosaur isn’t made more often in toy form.

This Brontosaurus figure was made in Japan and belongs to the “SF movie selection” collection, which consists of little models based on the 1933 “King Kong” movie. It is produced by the company Konami and is licensed by RKO Pictures Inc.

Review: Brachiosaurus (Wild Safari By Safari Ltd) (2010 Version)

Safari Ltd. released their first Brachiosaurus figure in 1989, and it remained the largest prehistoric figure in their entire collection for two decades. Despite the changes in paint application, its mold has been unchanged to this very day.
