In 2021, paleontologists made headlines with the discovery of a never-before-seen species of mosasaur, a marine reptile that roamed the oceans during the Late Cretaceous period. Named Xenodens calminechari, this species was described as having unique, saw-like teeth, setting it apart from other mosasaurs.However, a new study published on December 16, 2024, in Anatomy Notes suggests that the fossil may be a fake, casting doubt on the original findings.
The fossil in question—a jawbone with four sharp teeth—was unearthed in a phosphate mine in Khouribga province, Morocco. Researchers initially hailed it as a groundbreaking discovery, citing its unusual dental structure as evidence of a new species. But discrepancies in the fossil’s composition have led scientists to question its authenticity.
“If this fossil is indeed fake, it should be confirmed in the published literature that it is indeed fake,” said Henry Sharpe, a University of Alberta researcher and lead author of the new study, in an interview with LiveScience.
To verify the fossil’s legitimacy, researchers have ordered a computed tomography (CT) scan of the remains. This advanced imaging technique will reveal whether the jawbone is genuine or a cleverly crafted forgery.
The Original Discovery and Its Implications
The original study, published in ScienceDirect, described Xenodens calminechari as a mosasaur with teeth resembling a saw blade. These teeth were unlike anything seen in other mosasaurs,which typically had conical or blade-like teeth adapted for different diets.Mosasaurs were apex predators during the Cretaceous period, dominating the oceans with lengths ranging from 10 to 50 feet (3 to 15 meters).Their diverse tooth shapes reflected their varied feeding habits, from crushing shells to slicing through flesh.
The discovery of Xenodens calminechari was especially exciting as it suggested a new niche in the mosasaur family tree. However, the new study highlights inconsistencies in the fossil’s structure, raising concerns about its authenticity.
why the Fossil Might Be Fake
The researchers identified several red flags in the fossil’s composition. As an example, the teeth appear to be unnaturally fused to the jawbone, a feature not commonly seen in genuine fossils. Additionally, the mineral composition of the fossil differs from other specimens found in the same region.
“The teeth led the team in 2021 to make claims about their uniqueness, and they were key to the questions asked in the new study,” the authors wrote in Anatomy Notes.
if the CT scan confirms that the fossil is fake,it would be a significant blow to the paleontological community. Fossil forgery is not uncommon, especially in regions like Morocco, where the lucrative fossil trade has led to the creation of composite or entirely fabricated specimens.
What This Means for Paleontology
The potential forgery of Xenodens calminechari underscores the importance of rigorous verification processes in paleontology. While the original discovery was celebrated as a breakthrough, the new findings highlight the need for caution when interpreting fossil evidence.
“It’s a reminder that not all fossils are what they seem,” said Sharpe.The study also raises questions about the broader implications of fossil forgery. Fake fossils can distort our understanding of prehistoric life, leading to incorrect conclusions about species diversity and evolution.

A fossil once celebrated as evidence of a unique mosasaur species, Xenodens calminechari, is now under scrutiny. Discovered in a Moroccan mine and described in 2021, this 72-million-year-old fossil may be a forgery, according to a recent study. The findings, published in The Anatomical Record, reveal anomalies that challenge its authenticity, sparking a heated debate in the paleontological community.
The fossil, initially hailed for its “small, short, blade-like teeth, grouped together to form a saw-like edge,” was considered a groundbreaking discovery. Researchers claimed this feature was “unique among squamata” (the mosasaur order) and even among tetrapods, or four-legged vertebrates. However, a closer examination has raised red flags.
One of the most glaring inconsistencies lies in the fossil’s dental structure. Unlike all other known mosasaur species, which have one tooth per socket, this specimen shows two adjacent teeth sharing a single dental cavity. “Each dental crown has its own home,” explained Michael Caldwell,a professor of biological sciences at the university of Alberta and co-author of the new study. “Rather of being made from jawbone, tooth sockets are made from bone that develops from the tooth itself.”
This biological contradiction has led researchers to question the fossil’s origins. The study suggests that the specimen may have been artificially altered or fabricated,casting doubt on its scientific value.
The implications of this discovery are significant.If proven to be a forgery, the fossil could undermine previous research and highlight the challenges of verifying ancient specimens, especially those sourced from commercial mines.

Controversy Surrounds Alleged Mosasaur fossil: Is It a Fake?
A recent study has cast doubt on the authenticity of a fossil believed to belong to a new species of mosasaur, sparking a heated debate in the paleontology community.the fossil,which was discovered in a phosphate mine known for producing fossils with altered characteristics,has raised concerns about possible fakery due to unusual dental features and the circumstances surrounding its excavation.
The Fossil in Question
The fossil, identified as the holotype—the official specimen representing a new species—was first described in a 2021 paper by Nick Longrich, a paleontologist at the University of Bath. Though,a new study led by Mark Powers,a PhD candidate at the University of Alberta,suggests that the fossil may not be genuine.According to powers, the fossil exhibits “medial overlap,” a feature where two teeth appear to have a small amount of material extending along one side. “The fact that there is medial overlap is a good indicator of possible fakery,” Powers told Live Science. This overlap is inconsistent with the normal development of mosasaur teeth, which continuously replace themselves throughout their lives.
Red Flags in the Research Process
The controversy deepened when Sharpe,a researcher involved in the new study,contacted Longrich to discuss the fossil. Longrich reportedly asked, “What is the article’s point of view?”—a question that Sharpe described as raising “red flags.”
“That’s the holotype,” Sharpe emphasized. “Scientists cannot hide data about a holotype or the holotype itself as other researchers do not support their hypothesis. It would be very unethical for him to ask for it.” Longrich has not responded to requests for comment regarding the new study’s claims.
Unusual Dentition and CT Scan Limitations
The fossil’s dentition has also drawn scrutiny. Paulina Jimenez Huidobro, a paleontologist at the University of Bonn who was not involved in either study, noted that “the dentition appears unusual in both morphology and implantation.” she explained that having multiple teeth in one socket indicates “the tooth doesn’t belong in that jaw.”
Unfortunately, the fossil cannot be scanned using CT technology, which would allow researchers to examine its internal structure and differentiate between materials based on density. “That’s very unfortunate,” Jimenez Huidobro added.
Table: Key Points of the Controversy
| Aspect | Details |
|————————–|—————————————————————————–|
| Fossil Discovery | Found in a phosphate mine known for fossils with altered characteristics. |
| Dental Anomalies | Medial overlap and multiple teeth in one socket suggest possible fakery.|
| Holotype Concerns | Questions raised about clarity and ethical handling of the specimen. |
| CT Scan Limitations | Fossil cannot be scanned, hindering further analysis.|
The Broader Implications
This controversy highlights the challenges paleontologists face when dealing with fossils from regions known for producing altered or forged specimens. It also underscores the importance of transparency and ethical practices in scientific research, particularly when dealing with holotypes that serve as the foundation for new species descriptions.
As the debate continues, researchers hope to uncover the truth behind this enigmatic fossil. For now, the scientific community remains divided, with some supporting the original findings and others calling for further inquiry.

Versity in Casablanca, has raised concerns about the exploitation and potential forgery of fossils from the region. Bel hauz emphasizes that Morocco’s phosphate mines, which are renowned for producing exceptional fossils, are also hotspots for unethical practices, including the alteration or fabrication of specimens to increase their market value.
“The absence of strict regulations and oversight has created an environment where fossils are often mishandled or misrepresented,” Bel hauz explained.“This not only jeopardizes scientific integrity but also undermines Morocco’s cultural and scientific heritage.”
The Role of Commercial Fossil Trade
The commercial fossil trade plays a significant role in this issue. Fossils from Morocco, including those of mosasaurs, plesiosaurs, and other marine reptiles, are highly sought after by collectors and museums worldwide. Though, the lucrative nature of this trade has led to instances of forgery and tampering.
“Fossils are often modified to make them more visually appealing or to fit a particular narrative,” said Dr. Nour-Eddine Jalil, a paleontologist at the Natural History Museum of Paris. “This can include adding teeth, altering bone structures, or even combining parts of different fossils to create a ‘new’ species.”
Call for Legislation and Collaboration
to address these challenges, Bel hauz and other researchers are advocating for the implementation of protective legislation in Morocco. Such laws would regulate the excavation, sale, and export of fossils, ensuring that they are preserved for scientific study rather than commercial gain.
“We need a legal framework that prioritizes scientific research and protects our fossil heritage,” Bel hauz said. “This includes establishing permits for excavation, creating a national fossil registry, and collaborating with international institutions to ensure transparency and accountability.”
International Collaboration and Ethical Practices
The controversy surrounding the alleged mosasaur fossil underscores the importance of international collaboration and ethical practices in paleontology. Researchers are calling for greater transparency in the handling of holotypes and other significant specimens, and also the use of advanced technologies like CT scanning to verify the authenticity of fossils.
“Paleontology is a global endeavor,” said Dr. Michael Caldwell, co-author of the recent study questioning the authenticity of the mosasaur fossil. “We must work together to ensure that our discoveries are based on rigorous science and that we uphold the highest ethical standards.”
Table: Proposed Measures to Protect Morocco’s Fossil Heritage
| Measure | Details |
|————————–|—————————————————————————–|
