Hadrosaurine

The Hadrosaurine is a term that refers to a group of hadrosaurid dinosaurs that belong to the subfamily Saurolophinae.
Hadrosaurids, also known as duck-billed dinosaurs, are a family of herbivorous dinosaurs that lived during the Late Cretaceous period, about 86 to 66 million years ago.
They are characterized by their flat, broad snouts and complex teeth that allowed them to chew tough plant material.

The Hadrosaurine dinosaurs were widely distributed across the world, and their fossils have been found in Asia, North America, Europe, Africa, and South America.
Some of the most well-known genera of Hadrosaurine include Edmontosaurus, Saurolophus, Shantungosaurus, and Maiasaura.
They varied in size, shape, and ornamentation, but they all shared a common ancestor that lacked a crest on the head.
Some Hadrosaurine dinosaurs had solid bony bumps or spikes on their skulls, such as Gryposaurus and Brachylophosaurus.

Hadrosaurine dinosaurs were facultative bipeds, meaning that they could walk on either two or four legs depending on the situation.
They had long, muscular tails that helped them balance and steer when running.
They also had strong limbs and claws that could dig up roots and tubers.
Hadrosaurine dinosaurs were social animals that lived in large herds and migrated seasonally.
They also cared for their young and defended them from predators.
Hadrosaurine dinosaurs were among the most successful and diverse groups of dinosaurs, and they survived until the end of the Cretaceous period, when a mass extinction event wiped out most of the life on Earth.
