What is the animal Sauropodomorph known for?

Sauropodomorphs are a group of dinosaurs that are known for their long necks, small heads, and herbivorous diets.
They include the sauropods, which were the largest land animals ever, and their ancestors, which were smaller and sometimes bipedal.
Sauropodomorphs lived from the Late Triassic to the end of the Cretaceous, and were the dominant terrestrial herbivores for much of that time.

Some of the features that distinguish sauropodomorphs from other dinosaurs are:
  • A downward-bending tip of the lower jaw, which may have been used as a beak.
  • Lanceolate or spatulate teeth, which were adapted for slicing plant material.
  • A long neck with at least 10 cervical vertebrae, which allowed them to reach high foliage.
  • A large thumb claw, which may have been used for defense or digging.
  • A short blade-like extension of the ilium, the uppermost bone of the pelvis.
  • Specialized structures on the pelvis and hand, which helped them support their weight and balance.
Sauropodomorphs evolved from basal saurischians, such as Saturnalia, in the Late Triassic.
They diversified into many forms, such as Plateosaurus, Massospondylus, and Riojasaurus, which are sometimes called prosauropods.
These were mostly medium-sized, and could walk on two or four legs.
Some of them, such as Eoraptor and Buriolestes, may have been omnivorous or carnivorous.

The sauropods, which are the most derived sauropodomorphs, appeared in the Late Triassic or Early Jurassic.
They were fully quadrupedal, and grew to enormous sizes, reaching up to 40 meters in length and 80 tons in weight.
They had very long necks and tails, which were supported by strong ligaments and muscles.
They also had hollow bones, pneumatic cavities, and air sacs, which reduced their weight and improved their respiration.
Some of the best-known sauropods are Diplodocus, Brachiosaurus, Apatosaurus, and Argentinosaurus.

Where does the Sauropodomorph live?

Sauropodomorphs were a group of long-necked, herbivorous dinosaurs that lived from the Late Triassic to the Late Cretaceous, about 230 to 66 million years ago.
Sauropodomorphs inhabited a variety of environments, from deserts to forests to coastal plains.
They were the dominant terrestrial herbivores for much of the Mesozoic Era.
Their fossil remains have been found on every continent, including Antarctica, and have fascinated scientists and the public alike for their impressive size and diversity.
