What kind of herbivorous dinosaurs come to mind?

In this article, we will delve into the appeal of representative herbivorous dinosaurs, ranging from the super-gigantic species—the largest animals in Earth’s history—to those with uniquely shaped bodies.

The Largest Land Animals: Colossal Sauropodomorphs

The epitome of herbivorous dinosaurs is the quadrupedal Sauropodomorpha.

This group includes Seismosaurus (over 40m long) and Argentinosaurus, among others.

These dinosaurs are among the largest land animals in Earth’s history, and their colossal size is truly overwhelming.

Sauropodomorphs are also characterized by their long necks and long tails.
The length of their necks is evidence of the incredibly tall and large plants that grew in ancient times, telling the story of how much food they needed to sustain their gigantic bodies.

Appealing Diversity! Other Representative Herbivorous Dinosaurs

In addition to Sauropodomorphs, there were many diverse groups of herbivorous dinosaurs.

Horned and Dome-Headed Dinosaurs (Marginocephalians)

This group includes the bipedal Pachycephalosaurus and Triceratops, with its armor-like body and two large horns.
Triceratops is particularly popular, known for its distinctive head frill.

Furthermore, some herbivores had truly unusual appearances.

For example, Euoplocephalus had countless spikes growing on a back that resembled a rigid turtle shell.
