Description

Eocursor is a small dinosaur that lived in South Africa during the Late Triassic period, approximately 210 million years ago.

This bipedal dinosaur is known as an important figure, considered either an early primitive ornithopod or a close relative to the ancestor of all ornithopods.

True to the Name “Dawn Runner”! Speedy Feet Specialized for Escape

Origin and Meaning of the Name

The scientific name “Eocursor” carries the meaning “Dawn Runner.”
True to its name, they possessed high physical abilities specialized for running.

Long Shin Bones = Proof of High-Speed Running

A characteristic of the discovered fossils is that the shin bones are longer than the femurs (thigh bones).
Biologically speaking, this leg structure indicates suitability for high-speed running.

At that time, the best defense for Eocursor against predators like carnivores was not to fight.
It is believed that their survival strategy was to use their long legs to run away at high speeds.

Iguana-like Teeth and Herbivorous Ecology

Leaf-shaped Teeth

Its mouth was lined with “leaf-shaped” teeth.
These teeth closely resemble those of the modern green iguana, telling us that they were adapted to eat plants efficiently.

A small herbivorous dinosaur with iguana-like teeth, dashing like the wind across the land over 200 million years ago.
That is the true image of Eocursor.

The Roots of Ornithopods? An Important Taxonomic Position

Regarding classification, there is a theory that it is not a true ornithopod, but as an early dinosaur, it is certainly positioned close to the evolutionary roots of ornithopods.
Eocursor is positioned as a crucial entity for understanding the origins of the ornithopods that flourished in later eras (such as Iguanodon and Hadrosaurus).
