CollectA Iguanodon Dinosaur - Iguana Tooth Thumb Spike Herbivore Brown #88145

The Iguana Tooth with Defensive Thumb Spikes!

The CollectA Iguanodon #88145 brings one of the most historically important dinosaurs to life with exceptional detail. This bulky herbivore featured one of the most unusual hand structures ever discovered—large defensive thumb spikes combined with long, prehensile fifth fingers perfect for grasping vegetation. As one of the first dinosaurs ever scientifically described, Iguanodon holds a special place in paleontology history.

The Iguana Tooth Dinosaur

Iguanodon bernissartensis, meaning "iguana tooth," lived approximately 126-125 million years ago during the Early Cretaceous Period across Europe. Growing up to 33 feet long and weighing around 3 tons, Iguanodon was a successful herbivore that could shift between walking on two legs (bipedal) and four legs (quadrupedal) depending on whether it was moving or feeding. The name comes from its teeth, which resembled those of modern iguanas.

The Remarkable Thumb Spike

Iguanodon's most distinctive feature was the large, conical spike on each thumb. For years, paleontologists mistakenly thought this spike belonged on the nose (like a rhinoceros horn), but later discoveries revealed its true position. These thumb spikes, which could reach several inches in length, were likely used for defense against predators, combat with rivals, or breaking into seeds and fruits. The sharp, bony spikes made Iguanodon a formidable opponent despite being a peaceful herbivore.

One of the First Dinosaurs Ever Discovered

Iguanodon holds a special place in paleontology history as one of the first dinosaurs ever scientifically described. Discovered in England in 1822 by Mary Ann Mantell (though credit was given to her husband Gideon), Iguanodon was only the second dinosaur to be formally named. The famous discovery of dozens of complete Iguanodon skeletons in a Belgian coal mine in 1878 revolutionized our understanding of dinosaur anatomy and posture.

Versatile Hands for Feeding

Beyond the defensive thumb spikes, Iguanodon had remarkably versatile hands. The middle three fingers were hoof-like for walking, while the fifth finger was long and flexible—almost like a human thumb—allowing Iguanodon to grasp branches and pull vegetation to its mouth. This combination of defensive weapons and grasping ability made Iguanodon's hands some of the most specialized in the dinosaur world.

Bipedal or Quadrupedal?

Iguanodon was one of the first dinosaurs discovered to be capable of both bipedal and quadrupedal locomotion. When moving quickly or reaching for high vegetation, it could rear up on its powerful hind legs. When feeding on low plants or moving slowly, it could drop to all fours, using its hoof-like middle fingers for support. This versatility gave Iguanodon advantages in both feeding and escaping predators.
