Fruitadens haagarorum

† Fruitadens haagarorum — a Late Jurassic heterodontosaurid from Colorado, United States. Tiny omnivore (~75 cm, ~200 g); one of the smallest adult dinosaurs known. Named for the Haagar family. Possessed fang-like teeth mixed with leaf-shaped grinding teeth, suggesting an omnivorous diet.

Diet & Feeding

Herbivore

Fruitadens haagarorum was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Late Mesozoic Era

Fruitadens haagarorum lived during the Jurassic Late period of the Mesozoic Era, approximately 161,5 to 145,0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
