Mantellisaurus atherfieldensis

Navaornis hestiae was a Cretaceous bird from Spain, a small enantiornithine from the Late Cretaceous of Tremp Basin. This Spanish Cretaceous bird adds to the diverse enantiornithine fauna of the Ibero-Armorican archipelago during the Campanian-Maastrichtian.

Diet & Feeding

Herbivore

Mantellisaurus atherfieldensis 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

Mantellisaurus atherfieldensis 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.
