It’s Shark Week, and what better time to showcase some of the incredible fossil shark teeth we have available here at Wyoming Fossils!

From the massive, iconic Megalodon, to sleek Mackerel sharks, the fearsome Squalicorax (Crow Shark) that swam alongside the dinosaurs, the striped predator Galeocerdo (Tiger Shark), the broad-toothed Planus, and the ever-popular Hastalis, our collection spans millions of years of shark evolution.

Each tooth is a genuine piece of prehistoric history, preserving a glimpse into ancient oceans that existed long before today’s sharks ruled the seas.

Which one is your favorite? Let us know in the comments! 🦈

If only it were that easy! One tap of the hammer and—boom—a perfectly prepared Green River Formation stingray appears. Unfortunately, fossil preparation is pretty much the exact opposite.

Real fossil prep takes hours (and sometimes days or even weeks) of carefully removing rock grain by grain with specialized tools, constantly stabilizing delicate fossils, and making sure millions of years of history aren’t damaged in the process. One wrong move can mean losing irreplaceable detail forever.

So while SpongeBob may make sculpting look effortless, we’ll stick to patience, precision, and a lot of dust. 😅

🦴 Fossil featured: Heliobatis, an extinct freshwater stingray from Wyoming’s famous 50-million-year-old Green River Formation.

“You’re gonna suffer… but you’re gonna be happy about it.” 😂

That pretty much sums up fossil hunting during the Wyoming summer. Long days under the blazing sun, dust everywhere, sore muscles, and plenty of sweat—but then you uncover an incredible fossil, and suddenly it all feels worth it.

The heat may be relentless, but the next T. rex tooth, Triceratops bone, or rare fossil could be just one shovel scoop away. That’s the addiction of fossil hunting! 🦖☀️

Who else has a hobby that makes them question their life choices… but they keep coming back for more? 😅

Watch as the broken tip and a small shard of an authentic Tyrannosaurus rex tooth are carefully prepared and repaired. Fossils rarely come out of the ground in perfect condition, and even small fragments can be incredibly important to preserve. Using professional fossil preparation techniques and conservation-grade adhesives, each piece is meticulously aligned and stabilized to restore the specimen while preserving its natural appearance.

Interestingly, complete T. rex teeth are much less common than isolated tips and shards. As T. rex fed, its teeth regularly struck bone, causing the ends to chip and break. Like other theropod dinosaurs, T. rex continually replaced its teeth throughout its life, so these broken fragments were left behind while new teeth grew in to take their place. Because of this, tooth tips and enamel shards are some of the most frequently discovered remains of these incredible predators.

Every repair is a careful process, ensuring these rare pieces of prehistoric history remain stable and preserved for future generations.

Join us as we repair and prepare a rooted Edmontosaurus tooth recovered from the famous Lance Creek Formation. This specimen required careful stabilization before preparation, using PaleoBond 750 to secure the two broken pieces together. An activator spray was then applied to rapidly cure the adhesive, allowing the tooth to be safely handled during the preparation process.

Once stabilized, the surrounding matrix was removed with an air abrasive unit. This precision tool uses a controlled stream of abrasive media propelled by compressed air to gently remove rock while minimizing damage to the fossil itself. The technique is especially useful for delicate specimens like dinosaur teeth, where preserving fine details of the root and enamel is critical.

Edmontosaurus was a large duck-billed dinosaur, or hadrosaur, that lived during the Late Cretaceous alongside animals such as Tyrannosaurus, Triceratops, and Ankylosaurus. It was one of the most common herbivores of its time and possessed massive dental batteries containing hundreds of teeth that were continuously replaced throughout its life. The rooted teeth occasionally found as fossils provide an incredible glimpse into that complex feeding system.

Watch as this ancient tooth is brought back from a fractured field find to a fully prepared display specimen, revealing details that have been hidden in the rock for over 66 million years.

In this video, we take a closer look at the preparation of a rare double-rooted Triceratops tooth from the Lance Creek Formation. Using an air abrasive unit, the surrounding rock matrix is carefully removed to reveal delicate details that would be difficult to expose with traditional hand tools alone.

An air abrasive unit works much like a miniature sandblaster, using compressed air to propel a fine abrasive powder at the fossil’s surface. This allows preparators to remove matrix with incredible precision while minimizing the risk of damaging fragile fossil material. It is an invaluable tool for revealing fine features, cleaning tight spaces, and bringing fossils to their full display potential.

What makes this specimen especially interesting is its double-rooted structure. Most isolated Triceratops teeth are found as single-rooted teeth, often because the roots break apart before or during fossilization. Finding a tooth with both roots intact is much less common and provides a more complete look at the anatomy of the animal’s dental battery. These well-preserved specimens help paleontologists and collectors better understand how Triceratops continually replaced and used its teeth to process tough vegetation.

Stay tuned as this remarkable tooth emerges from the rock and reveals details that have been hidden for over 66 million years beneath the ancient sediments of the Lance Creek Formation.

Watch as “The Master” Robert Bowen carefully prepares a rare rooted Pachycephalosaurus tooth recovered from Wyoming’s Lance Creek Formation. Using an air abrasive unit, Robert meticulously removes the surrounding rock matrix to reveal the fossil hidden beneath millions of years of sediment.

An air abrasive unit works much like a miniature sandblaster, using a controlled stream of fine abrasive powder and compressed air to remove rock grain by grain. This allows delicate fossils to be exposed with incredible precision while minimizing the risk of damage.

Pachycephalosaurus was a dome-headed herbivorous dinosaur that lived during the Late Cretaceous, around 66 million years ago. Best known for its thick skull roof, it roamed alongside animals such as Triceratops, Edmontosaurus, Tyrannosaurus rex, and numerous crocodilians in the ancient ecosystems preserved within the Lance Creek Formation.

It’s always exciting to see a rooted dinosaur tooth emerge from the matrix, and Robert’s steady hand makes the process look easy—though fossil preparation is anything but! Be sure to follow along for more fossil preparation and excavation videos from Wyoming’s prehistoric past.

One year ago today, I shared the preparation of this rare mammal jaw recovered from the Lance Creek Formation of Wyoming, and it’s still one of my favorite fossils to have worked on.

Mammal fossils from the Lance Creek Formation are incredibly uncommon compared to the dinosaur bones and teeth that are typically found. Their small, delicate bones require careful preparation under magnification to reveal the fine details while preserving the specimen.

In this video, you’ll see the preparation process as the surrounding rock matrix is slowly removed, exposing more of the jaw and its tiny teeth. Fossils like this provide a rare glimpse into the small mammals that lived alongside dinosaurs during the final days of the Cretaceous Period.

It’s hard to believe it’s already been a year since working on this specimen, so I thought it was worth sharing again for anyone who may have missed it the first time around.

Join me in the field as I carefully excavate a large Borealosuchus tooth from the Late Cretaceous-aged Lance Creek Formation of Wyoming! In this video, I use a pick to slowly remove the surrounding matrix while working around the fossil, followed by the application of PaleoBond to stabilize the specimen and help protect it during extraction.

Borealosuchus was a crocodilian that lived alongside some of the last dinosaurs, including Triceratops, Edmontosaurus, and Tyrannosaurus rex. As an ambush predator inhabiting rivers, lakes, and wetlands, it played an important role in the ecosystem and may have scavenged or preyed upon smaller animals that shared its environment.

Field excavation requires patience and precision. Fossils can be surprisingly fragile after spending millions of years buried underground. Even a seemingly solid tooth can contain hidden fractures, making stabilization and careful removal essential to preserving the specimen. One wrong move can mean the difference between recovering a beautiful fossil and losing important scientific information.

Watch as this incredible crocodilian tooth is uncovered step-by-step from the ancient sediments of the Lance Creek Formation!

Our recent trip to a Lance Creek Formation quarry turned into an incredible tooth-hunting adventure! In this video, we showcase some of the amazing teeth recovered from one of Wyoming’s most fossil-rich Late Cretaceous deposits.

Among the finds are teeth from iconic dinosaurs such as the horned giant Triceratops, the duck-billed Edmontosaurus, the apex predator Tyrannosaurus rex, and the ever-debated Nanotyrannus. We also recovered teeth from armored dinosaurs like Denversaurus, dome-headed pachycephalosaurs, swift dromaeosaur (“raptor”) predators, and several species of ancient crocodilians that inhabited the rivers and floodplains of the Lance Creek ecosystem.

Tooth fossils are often some of the most exciting discoveries from the Lance Creek Formation. Each tooth provides a glimpse into the incredible diversity of herbivores, predators, and scavengers that lived here roughly 66 million years ago.

And this is only the beginning! Several of the teeth featured in this video will be undergoing preparation, cleaning, and restoration in upcoming videos, so be sure to stay tuned to watch these fossils emerge from the surrounding rock and reveal even more detail.
