Animantarx ramaljonesi

†Animantarx ramaljonesi was a nodosaurid ankylosaur herbivore of the Early Cretaceous, discovered in Utah, United States. Measuring approximately 3m in length, it was a low-browsing quadruped armoured with bony osteoderms along its back and flanks but lacking the tail club of true ankylosaurids. Its fossils were found in the Cedar Mountain Formation.

Diet & Feeding

Herbivore

Animantarx ramaljonesi 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

Animantarx ramaljonesi 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.
