What did Amargasaurus live with?
Since Amargasaurus is a sauropod it was most likely an herbivore. It probably lived off of a diet of seed ferns, gingkos, club mosses and cycads.
When did the Amargasaurus live?
129.4 million years ago – 122.46 million years ago (Barremian – Aptian)
Amargasaurus/Lived
How tall is an Amargasaurus?
Amargasaurus probably fed at mid-height, as shown by the orientation of its inner ear and the articulation of its neck vertebrae, which suggest a habitual position of the snout 80 centimeters (31 inches) above the ground and a maximum height of 2.7 meters (8.9 feet).
Who discovered Amargasaurus?
Jose F. Bonaparte
Unfortunately, our knowledge of Amargasaurus is limited by the fact that only one fossil specimen of this dinosaur is known, discovered in Argentina in 1984 but only described in 1991 by the prominent South American paleontologist Jose F. Bonaparte.
Who discovered the Amargasaurus?
When did the Amargasaurus go extinct?
The Amargasaurus, a sauropod dinosaur, became extinct around 129.4-122.46 million years ago, by the end of the Barremian and Late Aptian stages of the Early Cretaceous period.
What did Amargasaurus eat?
Amargasaurus was an herbivore (it ate only plants). It must have eaten a large amount of plant material each day to sustain itself. It swallowed leaves whole, without chewing them, and may have had gastroliths (stomach stones) in its stomach to help digest this tough plant material.
What kind of environment did Amargasaurus live in?
Amargasaurus was discovered in sedimentary rocks of the La Amarga Formation, which dates back to the Barremian and late Aptian stages of the Early Cretaceous. A herbivore, it shared its environment with at least three other sauropod genera, which might have exploited different food sources in order to reduce competition.
How big was the Amargasaurus sauropod in feet?
This relatively slim plant-eater (“only” about 30 feet long from head to tail and two to three tons) had a row of sharp spines lining its neck and back, the only sauropod known to have possessed such an imposing feature.
What kind of spikes did an Amargasaurus have?
Two rows of bony spikes ran down its neck like a pointed mane, and its nostrils were located at the top of its head. With its large size and spikes, this creature could fight off some of the fiercest predators of the Cretaceous Period Toe Tool: Each of amargasaurus’ feet had one or two elongated claws on the inside edge.
What was the purpose of the Amargasaurus scaffold?
An alternate hypothesis, now less favored, postulates that they could have formed a scaffold supporting a skin sail. They might have been used for display, combat, or defense. Amargasaurus was discovered in sedimentary rocks of the La Amarga Formation, which dates back to the Barremian and late Aptian stages of the Early Cretaceous.
