Enigmacursor mollyborthwickae

† Enigmacursor mollyborthwickae — a Late Jurassic ornithopod dinosaur from the Morrison Formation, United States. Small-bodied herbivorous biped. The name 'enigma runner' reflects uncertainty about its phylogenetic placement. Represents rare small ornithopods in the diverse Morrison fauna.

Diet & Feeding

Herbivore

Enigmacursor mollyborthwickae 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

Enigmacursor mollyborthwickae 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.
