How Much Is A Dinosaur Tooth Worth? An In-Depth Look At Dinosaur Tooth Values

Dinosaur teeth have fascinated people for generations. Their rarity and prehistoric origins make them highly coveted by collectors and museums. But have you ever wondered, how much is a dinosaur tooth actually worth? The answer depends on several factors.

If you’re short on time, here’s a quick answer to your question: A small, common dinosaur tooth could be worth $20-$50. More unique or complete specimens could sell for hundreds, thousands, or even millions of dollars at auction.

What Makes Dinosaur Teeth Valuable

Dinosaur teeth are highly sought after by collectors, scientists, and enthusiasts alike. Their value is determined by several factors, including:


The rarity of a dinosaur tooth greatly influences its value. Some dinosaur species are more commonly found than others, making their teeth less valuable. However, teeth from rare or newly discovered species can fetch a high price in the market. For example, the teeth of the Tyrannosaurus Rex are highly valued due to their scarcity and the iconic status of the dinosaur itself.


The species of dinosaur to which a tooth belongs also plays a significant role in determining its value. Certain species, such as the T. Rex mentioned earlier, have a higher desirability among collectors. The size and shape of the tooth can also impact its value. For example, the serrated teeth of a Spinosaurus, known for its aquatic adaptations, may be more valuable due to their unique characteristics.

Completeness and Condition

The completeness and condition of a dinosaur tooth are crucial factors in determining its value. Teeth that are intact and well-preserved are generally more valuable than those that are damaged or fragmented. A tooth with complete root and enamel is considered more valuable, as it provides important information about the dinosaur’s diet, age, and overall health.


The provenance, or the documented history and origin, of a dinosaur tooth can significantly impact its value. Teeth that come with detailed information about their excavation site, the paleontologist who discovered them, and any scientific significance they hold are often more desirable. Provenance adds to the authenticity and credibility of the tooth, making it more valuable to collectors and researchers alike.

It is important to note that the value of dinosaur teeth can vary greatly depending on these factors, as well as market demand and other external factors. If you are considering purchasing or selling a dinosaur tooth, it is advisable to consult with experts or reputable dealers to get an accurate valuation.

Where to Buy or Sell Dinosaur Teeth

Interested in buying or selling a dinosaur tooth? There are several options available to you, ranging from auction houses to online marketplaces. Each option has its own advantages and considerations, so it’s important to explore your options before making a decision.

Auction Houses

Auction houses are a popular choice for those looking to buy or sell dinosaur teeth. These establishments often have a wide selection of fossils available for bidding, including unique and rare specimens. Auctions can be an exciting way to acquire a dinosaur tooth, as prices can vary depending on the demand and rarity of the specimen.

It’s important to do your research and understand the auction process before participating. Some well-known auction houses that frequently deal with dinosaur fossils include Sotheby’s and Christie’s. These reputable establishments have experts who can provide valuable insights and guide you through the buying or selling process.

Fossil Dealers

Fossil dealers are another option for those interested in buying or selling dinosaur teeth. These dealers specialize in the trade of fossils and often have a vast collection of specimens to choose from. They may have a physical store or operate online, making it convenient for buyers to browse and compare different offerings.

When choosing a fossil dealer, it’s important to ensure their credibility and expertise. Look for dealers who have a good reputation, positive customer reviews, and certifications, such as membership in professional fossil organizations. This will ensure that you are dealing with a reputable seller who can provide accurate information about the dinosaur tooth’s origin and authenticity.

Online Marketplaces

Online marketplaces have become increasingly popular for buying and selling dinosaur teeth. Platforms like eBay and specialized fossil websites offer a wide range of options, allowing buyers to browse through various listings and compare prices. Online marketplaces provide convenience and accessibility, as you can shop from the comfort of your own home.

It’s important to exercise caution when purchasing from online marketplaces. Ensure that the seller has a good reputation and positive feedback from previous buyers. Additionally, carefully read the item description and look for clear and detailed photographs of the dinosaur tooth. If possible, ask the seller for additional information or certifications regarding the authenticity of the specimen.

Factors That Affect Value


One of the key factors that determine the value of a dinosaur tooth is its size. Generally, larger dinosaur teeth tend to be more valuable than smaller ones. This is because larger teeth are rarer and more desirable to collectors and museums. A tooth from a large carnivorous dinosaur like Tyrannosaurus rex can fetch a higher price compared to a tooth from a smaller herbivorous dinosaur. However, it’s important to note that there are exceptions to this rule, as some smaller teeth from extremely rare species can still be quite valuable.


The condition of a dinosaur tooth plays a significant role in determining its value. Teeth that are in excellent condition, with minimal damage or wear, are generally more sought after. This is because well-preserved teeth provide scientists with valuable information about the dinosaur’s diet, behavior, and overall health. On the other hand, teeth with significant damage or restoration may still hold some value, but they are typically priced lower due to their compromised state.

Species Rarity

The rarity of the dinosaur species to which the tooth belongs is another crucial factor in determining its value. Teeth from rare or lesser-known dinosaur species are highly sought after by collectors and researchers. For example, a tooth from a well-known species like the T. rex may be valuable, but a tooth from a more obscure dinosaur species that is rarely found in the fossil record could be even more valuable. The scarcity and uniqueness of the species contribute to the tooth’s worth.

Tooth Type

The type of tooth also affects its value. Different dinosaur species had different types of teeth, each adapted for specific purposes like slicing, crushing, or tearing. Teeth from apex predators like the T. rex or Allosaurus, which have large, serrated, and formidable teeth, tend to be more valuable due to their iconic status. Conversely, teeth from herbivorous dinosaurs, like the Triceratops or Stegosaurus, although still valuable, may not command as high a price as those from their carnivorous counterparts.

Where It Was Found

The place where a dinosaur tooth was found can also impact its value. Teeth discovered in famous and scientifically significant locations, such as the Hell Creek Formation in Montana or the Morrison Formation in Colorado, may hold higher value due to their historical and geological importance. Additionally, teeth with well-documented provenance, meaning a detailed record of their excavation and discovery, can help establish their authenticity and increase their value.

Legalities and Ethics

When it comes to buying or selling dinosaur teeth, it is important to consider the legalities and ethics surrounding these transactions. The fossil trade is regulated to protect paleontological heritage and ensure that these valuable specimens are not lost or exploited. Here are some key factors to consider:

Provenance Documentation

Provenance documentation refers to the historical record of a fossil’s origin and ownership. It is essential to have proper documentation that proves the tooth was legally obtained and has not been stolen or illegally excavated. This documentation helps establish the authenticity and legal status of the tooth, ensuring that it can be bought and sold without any legal complications.

Provenance documentation typically includes information such as the location of the fossil’s discovery, the name of the excavator, date of excavation, and any relevant permits or licenses. It is advisable to request and review this documentation before making a purchase to ensure compliance with legal requirements.

Export Regulations

Export regulations vary from country to country and are designed to prevent the illegal trafficking of fossils. Some countries have strict laws prohibiting the export of dinosaur teeth or other paleontological specimens. It is crucial to research and understand the export regulations of both the country where the tooth was found and the country where you intend to sell or buy it.

For example, the United States has specific laws governing the import and export of fossils, including dinosaur teeth. The sale or purchase of fossils without proper documentation or in violation of export regulations can result in legal consequences, including fines and confiscation of the specimen. It is essential to consult with experts or legal professionals familiar with these regulations to ensure compliance.

Supporting Scientific Institutions

Supporting scientific institutions play a crucial role in the legal and ethical trade of dinosaur teeth. Many collectors and sellers choose to work with reputable institutions that are committed to preserving and studying paleontological specimens. These institutions often have strict acquisition policies that ensure the ethical sourcing and documentation of fossils.

By purchasing or selling dinosaur teeth through these institutions, collectors and sellers can contribute to ongoing scientific research and help fund future excavations. Supporting reputable institutions also helps maintain transparency in the fossil trade and ensures that valuable specimens are cared for and made accessible to researchers and the public.

It is important to note that some scientific institutions may require the donation or loan of the tooth in exchange for their assistance in verifying its authenticity and legality. This collaborative approach further strengthens the ethical practices associated with dinosaur tooth transactions.

For more information on the legalities and ethics surrounding the trade of dinosaur teeth, you can visit the website of the Society of Vertebrate Paleontology at They provide valuable resources and guidelines to help collectors and sellers navigate the legal landscape of fossil trading.


From small fossils worth less than $100, to remarkable specimens auctioning for millions, dinosaur teeth come in a wide range of values. Rarity, quality, species, and market demand all influence price for these coveted prehistoric artifacts. With the right combination of characteristics, select dinosaur teeth can be worth a small fortune.
