What makes something scary, creepy, terrifying, or just so strange that it haunts our dreams? For some, all it takes is a spider or a snake; for others it needs to be an eldritch horror straight from H.P Lovecraft’s world. Many of the more famous prehistoric beasts gained notoriety because there’s something about them, be it the size of their teeth, that they’re covered in spikes, or their sheer size, that elicits a primeval sense of dread in our mammalian brains. Hopefully somewhere in this article is a creature that sends a bone chilling tingle up your spine; one that you’re glad went extinct. Now it can only haunt you in your dreams.
This 33 foot long armored fish from the Devonian era lacked teeth, but its jaw contained razor sharp protrusions of bone that it could use to pierce and cut through its prey. These bones grew continuously and as they did, the edges rubbed together with those of the opposing jaw, acting like self sharpening shears. This would ensure the “fangs” were always ready to chomp into armored prey like arthropods, ammonites and other fish. This four ton monster fish patrolled inshore waters and could snatch prey up by opening and closing its jaws within 50-60 milliseconds.
We just received a number of fossil Tyrannosaur (T-Rex & Nanotyrannus) teeth from the Hell Creek Formation of South Dakota. Tyrannosaurid teeth are typically are one of the fastest selling fossils we have and because of their collectability are hard for us to acquire.
These teeth come from a private quarry in Butte County, South Dakota operated by PaleoAdventures known as the “Tooth Draw Quarry” This quarry is known as the “Tooth Draw Quarry” and is renowned for having produced many high quality dinosaur teeth over the past several decades. In the Late Cretaceous some 65 million years ago, this quarry was located in a sub-tropical floodplain that would have been similar to modern day coastal Louisiana. It consists of 2 meters of alternating sandstone and gravel, representing a river channel lag deposit. This means that it doesn’t produce articulated dinosaur remains but is a good location to find teeth.
It's always interesting to be able to show the work that goes into a well prepared fossil specimen. Actually collecting the fossils is often the easier and less time consuming part than the preparation. This is a beautiful preparation sequence of a Metacanthina issoumourensis trilobite quarried near Lghaft, Morocco. Preparation and photos by Alex Žagar.
The trilobites are found within a hard limestone by breaking the rock into progressively smaller pieces and looking for thin cross-sections. This is backbreaking work, but once the trilobite back in the preparation lab the detailed work begins. The rock must be meticulously removed from around the trilobites under magnification using airscribes and air abrasives. It takes many hours to prepare even some of the less ornate trilobites.
Trilobites are an extinct marine animal that dominated Earth's oceans for 270 million years long before the first dinosaurs. There were over 25k known types some of them with very ornate shells covered in spines. This huge variety and their alien looking appearance makes them very appealing to collectors. We have a huge variety of trilobite fossils for sale ranging from inexpensive, common species to amazing museum quality specimens and everything in between. Buy fossils from us knowing you are getting authentic specimens, at the best value.
The Megalodon was a massive prehistoric shark that grew to lengths of up to 60 feet and went extinct 1.5 million years ago. It had giant teeth that could reach 7 inches in length (though only a handful have ever been found that large). For comparison the largest great white shark teeth did not reach 3 inches in length. Fossils of it's teeth can be found worldwide and are both impressive and terrifying. We have a wide selection of authentic Megalodon fossils for sale, starting around $10 which make great gifts, to collector quality teeth priced at $1,000+.
We have a wide selection of authentic dinosaur teeth for sale. Dinosaurs shed their teeth rapidly as they grew or they became worn and they were composed of a more solid material than bone so they tend to be much more common than complete bones. We have both affordable and premium examples of teeth from several different dinosaurs including Spinosaurus, Triceratops, T-Rex, Edmontosaurus, as well as large prehistoric reptiles like Mosasaurus.
Fish have been around in the fossil record for over 500 million years and are one of the most diverse animals on our planet. Fossil fish are some of the most aesthetic and collectable fossils out there. FossilEra has a selection of beautiful fish fossils for sale from the Green River Formation of Wyoming as well as several other locations around the world. Not only do these fish make for beautiful displays but they are tremendously interesting from a scientific and historical perspective.
