What is the State Dinosaur of Texas?

The Lone Star State, known for its rich history, diverse culture, and unique natural beauty, has a lesser-known but equally fascinating claim to fame: the Texas state dinosaur. But what exactly is this prehistoric creature that holds such a distinguished title? Allow us to introduce you to the Paluxysaurus jonesi, an extraordinary dinosaur species that once roamed the land we now know as Texas.

A Glimpse into the Past: Dinosaurs of Texas

Before we delve into the specifics of the Paluxysaurus jonesi, let’s take a quick look at the variety of dinosaurs that lived in Texas. The state’s geological history provides a fertile ground for numerous dinosaur species. From the carnivorous Acrocanthosaurus to the herbivorous Tenontosaurus, the diversity of dinosaur fossils found in Texas paints a vivid picture of a bygone era teeming with life.

One such dinosaur fossil, which stands out amongst all others, is that of the Texas state dinosaur – the Paluxysaurus jonesi. This majestic beast was a type of sauropod, a group of long-necked, four-legged, plant-eating dinosaurs known for their colossal size.

Introducing the Paluxysaurus Jonesi

The Paluxysaurus jonesi, named after the Paluxy River in Hood County where its fossils were first discovered, is the official state dinosaur of Texas. It was designated as such in 2009, replacing the previous state dinosaur, Pleurocoelus, which had held the title since 1997.

The change in the state dinosaur was brought about by new paleontological findings. Initially, the fossils found in Texas were believed to belong to Pleurocoelus, but further research suggested that they represented a distinct species – thus, Paluxysaurus jonesi was born.

The Majestic Sauropods

Paluxysaurus jonesi belonged to the group of dinosaurs known as sauropods. These creatures were renowned for their immense size and long necks. One of the most famous sauropods is the Sauroposeidon, which stood taller than any other dinosaur known to science. If you’re wondering how to pronounce Sauroposeidon, it’s “saw-ro-po-SIE-don”.

While the exact height of the Paluxysaurus jonesi is unknown, it’s estimated to have been similar in size to its relative, the Sauroposeidon. This would make it one of the tallest dinosaurs ever discovered, with an estimated height comparable to a six-story building!

Finding Dinosaur Fossils in Texas

But where exactly are these dinosaur fossils found in Texas? The state is rich in geological sites that have yielded significant dinosaur discoveries. Places like the Dallas-Fort Worth area, the Texas Hill Country, and the Big Bend National Park have all produced valuable dinosaur fossils over the years.

Many of these dinosaur fossils, including those of the Paluxysaurus jonesi, can be seen at various museums across the state. The Fort Worth Museum of Science and History, for instance, houses a life-sized model of the Paluxysaurus jonesi, giving visitors a glimpse into the state’s prehistoric past.

Beyond the State Dinosaur: The State Fossil and State Stone of Texas

While the Paluxysaurus jonesi holds the title of the state dinosaur, it’s not the only symbol of Texas’ rich geological history. The state fossil of Texas is the petrified palmwood, a type of fossilized wood that showcases the intricate patterns of ancient palm trees. This unique fossil serves as a testament to the lush tropical forests that once covered the region.

The state stone of Texas, meanwhile, is the blue topaz. This beautiful gemstone is found in abundance in the state, particularly in Mason County, and is prized for its stunning blue color.


From the towering Paluxysaurus jonesi to the delicate blue topaz, the natural symbols of Texas offer a fascinating glimpse into the state’s diverse geological and paleontological history. So, the next time you’re asked, “What is the Texas state dinosaur?” you’ll know the answer – and so much more!
