Floodwaters Uncover Texas Dinosaur Tracks: A Glimpse into a Lost World


 

Introduction

Recent flooding across central Texas has unearthed a remarkable marvel—ancient dinosaur footprints dating back over 110 million years. These fossilized traces offer us a real-world pathway into the Cretaceous era and stand as a testament to how nature can surprise us even amid devastation.

Discovery Amid Disaster

In the wake of the July 4 storms, volunteers clearing debris in the Big Sandy Creek area in Travis County stumbled upon fossilized tracks preserved in Glen Rose Limestone. The discovery was officially confirmed by UT Austin paleontologist Matthew Brown and supported by Travis County Judge Andy Brown.

What the Tracks Reveal

  • Age & Geology: The footprints are estimated at 110–115 million years old, tracing back to an ancient coastal mudflat—part of the Western Interior Seaway.

  • Track Makers: Some tracks appear to belong to large, bipedal carnivores like Acrocanthosaurus—a 30–35 ft predator—while others reflect massive herbivores resembling Paluxysaurus, Texas’s state dinosaur.

  • Location Sensitivity: Found on private land, the precise site remains undisclosed to protect it, but access is being coordinated with researchers and authorities.

The Science of Preservation

These prints are embedded in Glen Rose Limestone, a sediment layer that formed as fine-grained mud hardened into rock. Such conditions are ideal for preserving footprints in pristine detail—provided they escape erosion and frequent flooding.

Historic Echoes in Dinosaur Valley State Park

This new discovery echoes earlier finds at Dinosaur Valley State Park, near Glen Rose, where footprints from Acrocanthosaurus and the long-necked Sauroposeidon regularly reemerge in the Paluxy River during periods of drought. The area has held paleontological intrigue since the early 20th century, when tracks were excavated and even displayed at the American Museum of Natural History by Roland T. Bird.

Why It Matters for Americans

This discovery is more than a scientific footnote—it’s a cultural moment. It connects us to the deep-time legacy beneath our feet and serves as a powerful reminder of the Earth’s dynamic history. It also underscores the importance of preserving such sites, especially as extreme weather events become more frequent.

Looking Ahead: What’s Next

  • Documentation & Mapping: UT Austin paleontologists plan to return with advanced 3D imaging and GPS mapping to document these tracks in detail.

  • Conservation During Recovery: Officials are balancing flood cleanup with fossil preservation—guidance is ongoing to ensure equipment avoids sensitive areas.

  • Public Engagement: These finds reiterate the importance of public awareness—these prehistoric treasures may lie closer to home than many realize.

In Summary

Flooding in central Texas has unexpectedly unveiled fossilized dinosaur footprints—testaments to prehistoric predators and giants that once roamed what is now Travis County. Anchored in scientific context and mirrored by past discoveries, this event invites us all to step into the ancient world—and consider the stories written in stone.

How Unplugging Helped Me Build Deeper Relationships

In a world where most conversations happen through screens, I didn’t realize how shallow my connections had become. I was “talking” to 10 people at once — but never really talking to anyone. My days were filled with heart emojis, quick replies, and endless group chats, but my actual voice? Rarely used. Then, after a conscious decision to spend less time on my phone, something unexpected happened: My relationships got deeper. From Text Threads to Real Conversations When I stopped trying to keep up with every notification, I started making actual phone calls. The kind where you hear laughter, pauses, and the little sighs people make when they’re really thinking. My mom told me stories about her teenage years I’d never heard before. My best friend and I talked through a problem she’d been avoiding for weeks. These weren’t exchanges you could sum up in three emojis. Meeting the People Right Next to Me Without my face in a screen, I started noticing people around me. I met my neighbors ...
