† Invictarx zephyri — a Late Cretaceous nodosaurid ankylosaur from the Menefee Formation, New Mexico. Medium herbivore (~4–5 m long); 'undefeated fortress of the west wind.' Heavily armored with osteoderms and small spines. Contributes to the understudied Late Cretaceous ankylosaur fauna of the Am.

Diet & Feeding

Herbivore

Invictarx zephyri 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

Cretaceous Late Mesozoic Era

Invictarx zephyri lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
