Amargatitanis macni

†Amargatitanis macni was a titanosauriform sauropod from the Early Cretaceous (~130 Ma) of Neuquén, Argentina. A large quadrupedal herbivore from the La Amarga Formation, it was named by Apesteguía in 2007. Known from fragmentary axial skeleton material, it helps document the diversity of Early Cretaceous sauropods in South America before the major titanosaur radiation later in the period.

Diet & Feeding

Herbivore

Amargatitanis macni 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

Amargatitanis macni 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.
