titanosaurian
Noun: 1. A type of sauropod dinosaur: A titanosaurian is a member of the diverse group Titanosauria, characterized as large, quadrupedal, herbivorous dinosaurs. They typically had long necks, long tails, and small heads. 2. Specific anatomical features: This group is often noted for its distinctive vertebrae and body armor, which could include bony plates (osteoderms) embedded in the skin.
- Noun:
- The paleontologists discovered the fossilized remains of a titanosaurian in Patagonia.
- Argentinosaurus is one of the largest known titanosaurian genera.
- The exhibit features a skeleton of a titanosaurian, illustrating its immense size.
- Scientific classification: The term is used precisely in paleontology to refer to any dinosaur within the clade Titanosauria.
- The new findings suggest this species was a basal titanosaurian.
- Titanosaur (n): A common synonym for titanosaurian, often used interchangeably.
- Titanosauria (n): The scientific name for the broader clade or group that includes all titanosaurians.
- Sauropod (n): The larger infraorder that includes titanosaurians along with other families like diplodocids and brachiosaurids.
- Titanosaur
- Sauropod (in a broader, less specific sense)
The reference context describes a titanosaurian as "amphibious." This is an outdated characterization in modern paleontology. While some early sauropod theories suggested semi-aquatic lifestyles, current consensus is that titanosaurians, like most sauropods, were fully terrestrial animals. The primary defining features are their quadrupedal herbivory, long necks, and membership in the Titanosauria clade.
- amphibious quadrupedal herbivorous dinosaur with a long thin neck and whiplike tail; of the Cretaceous mostly in the southern hemisphere
