Polacanthidae

† Polacanthidae was an extinct vertebrate (Aves or Reptilia) from United States. A herbivore of the Early Cretaceous, it inhabited the ecosystems of this region. Fossils contribute to understanding the paleontological diversity of this area and time period.

Diet & Feeding

Herbivore

Polacanthidae 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 Early Mesozoic Era

Polacanthidae lived during the Cretaceous Early period of the Mesozoic Era, approximately 145,0 to 100,5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
