Dinosaur Names Beginning with X

When we think of dinosaurs, the first few names that come to mind often start with T, such as the infamous Tyrannosaurus Rex or the Triceratops. But did you know there are also fascinating dinosaurs that start with X? In this article, we will delve into the world of X dinosaurs, exploring their unique characteristics and history.

Xenotarsosaurus: The Mysterious Giant

The Xenotarsosaurus is one of the most well-known dinosaurs starting with X. First discovered in Argentina, this dinosaur belongs to the Abelisauridae family, which thrived during the Late Cretaceous period. The name Xenotarsosaurus means “strange tarsus lizard,” referring to its unusual ankle structure.

Although much about the Xenotarsosaurus remains a mystery due to the scarcity of fossil evidence, it’s believed to have been a bipedal predator, with strong hind limbs for fast pursuits and short arms similar to its cousin, the T-Rex. Its distinctive features make it a standout among dinosaurs that start with X.

Xuanhanosaurus: The Chinese Wonder

Next on our list of dinosaurs beginning with X is the Xuanhanosaurus. This dinosaur was found in China and lived during the Middle Jurassic period. Its name translates to “Xuanhan Lizard,” named after the region where its fossils were discovered.

The Xuanhanosaurus was a theropod, a group of carnivorous dinosaurs characterized by their hollow bones and three-toed limbs. It was relatively small compared to other theropods, but its swift agility and sharp teeth made it a formidable predator of its time.

Xenoposeidon: The Enigmatic Titan

Another fascinating dinosaur that starts with X is the Xenoposeidon. Its name, meaning “strange Poseidon,” reflects its enigmatic nature. Discovered in England, the Xenoposeidon lived during the Early Cretaceous period and is known only from a single fossilized vertebra.

This lack of comprehensive evidence makes it one of the most mysterious dinosaurs by name and image. Despite this, based on the size and structure of the discovered vertebra, scientists speculate that the Xenoposeidon was a massive sauropod, possibly one of the largest creatures to have ever walked the earth.

Xingxiulong: The Ancient Herbivore

The Xingxiulong is another dinosaur whose name begins with X. This dinosaur roamed China during the Early Jurassic period. Unlike our previously mentioned dinosaurs, the Xingxiulong was a herbivore, belonging to the group of dinosaurs known as ornithischians.

The Xingxiulong had a robust body, long neck, and short, sturdy legs. Its name translates to “Xingxiu dragon,” named after the region where its fossils were found. Its unique skeletal structure adds diversity to our list of X dinosaurs.


From the Xenotarsosaurus to the Xingxiulong, these dinosaurs starting with X showcase the incredible diversity and complexity of prehistoric life. Each dinosaur brings a unique story and set of characteristics, reminding us of the vastness of our planet’s history.

So the next time someone asks you about dinosaurs that start with X, or if you’re ever in a trivia game where you need to name things beginning with X, remember this list. Not only will it make you a dinosaur expert among your peers, but it’ll also provide a fascinating glimpse into the ancient world of dinosaurs.
