Alaskacephale gangloffi

†Alaskacephale gangloffi was a pachycephalosaurid dinosaur from the Late Cretaceous (~70 Ma) of Alaska, USA. Known only from a partial dome skull, this thick-skulled bipedal herbivore inhabited high-latitude Arctic environments. Named by Sullivan in 2006, its discovery demonstrates that pachycephalosaurs ranged far north, enduring polar conditions in Late Cretaceous Alaska.

Diet & Feeding

Herbivore

Alaskacephale gangloffi 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

Alaskacephale gangloffi 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.
