Dinosaur Names Beginning with ‘Y’

Delving into the world of dinosaurs is like embarking on a thrilling journey through time. Today, we’re exploring a special category: dinosaurs that start with ‘Y’. You might be surprised to know how many fascinating creatures have names beginning with ‘Y’. From Yinlong to Yandusaurus, Yimenosaurus, and more, let’s dive into this captivating prehistoric universe.

Understanding Dinosaurs

Before we delve into our list, it’s essential to understand what makes a dinosaur unique. Dinosaurs are a group of reptiles that appeared during the Mesozoic Era, between 230 and 65 million years ago. They include some of the largest animals to have ever lived on Earth. But not all dinosaurs were gigantic; some were as small as modern birds!

Now, without further ado, let’s explore the dinosaurs whose names start with ‘Y’.

Yinlong – The Hidden Dragon

The first dinosaur on our list is the Yinlong. Its name means “hidden dragon” in Chinese. The Yinlong dinosaur was a small herbivorous creature from the Late Jurassic period. It was one of the earliest ceratopsians, a group that later included the famous Triceratops. Despite its small size, the Yinlong was an important part of the dinosaur evolutionary tree.

Yandusaurus – The River Lizard

Next up is the Yandusaurus, a dinosaur named after the Yandu district in China where its fossils were found. This dinosaur lived in the Middle Jurassic period. It was a bipedal herbivore known for its long neck and small head, traits common among ornithischian dinosaurs. The Yandusaurus is a fascinating example of how diverse dinosaur life was millions of years ago.

Yimenosaurus – The Yimen Lizard

The Yimenosaurus, named after Yimen County in China, is another intriguing dinosaur that starts with ‘Y’. This dinosaur lived during the Early Jurassic period. It was a large, quadrupedal herbivore belonging to the family of “prosauropods”. With its long neck and tail, the Yimenosaurus is believed to have been an ancestor of the giant sauropods like Brachiosaurus and Apatosaurus.

Dangerous Dinosaurs Beginning with ‘Y’

While many dinosaurs beginning with ‘Y’ were herbivores, there were some carnivorous species too. One such dinosaur is the Yangchuanosaurus, a large theropod from the Late Jurassic period. This predator was similar in size and appearance to Allosaurus and was undoubtedly one of the most dangerous dinosaurs of its time.

Why Names Beginning with ‘Y’?

You might be wondering why so many dinosaur names start with ‘Y’. The answer lies in the place of their discovery. Many dinosaur fossils have been found in China, and it’s customary to name these prehistoric creatures after the locations where they’re discovered or the people who found them. Hence, many dinosaur names starting with ‘Y’ are derived from Chinese words or places.


Exploring the world of dinosaurs that start with ‘Y’ offers a fascinating glimpse into Earth’s prehistoric past. From the ‘hidden dragon’ Yinlong to the ‘river lizard’ Yandusaurus, and the ‘Yimen lizard’ Yimenosaurus, each of these creatures adds a unique piece to the puzzle of dinosaur evolution. They remind us of the rich biodiversity that once roamed our planet and continue to captivate the imagination of dinosaur enthusiasts around the world.
