Concerns Over Fossil Forgery
A groundbreaking discovery in the world of paleontology has sparked concerns over the authenticity of an ancient sea monster unearthed in a Moroccan mine. Xenodens calminechari, a newly described mosasaur species, may be based on forged fossils, according to a new study published on Dec. 16, 2024.
Lead author Henry Sharpe and his team from the University of Alberta are calling for computed tomography (CT) scans of the remains to verify the legitimacy of the 72.1 to 66 million-year-old jaw. The doubts arose after researchers found discrepancies in the fossil that indicate it could be a fake. If proven to be a forgery, it is crucial to establish this fact in the scientific literature.
Discovery of Xenodens calminechari
The original study describing Xenodens calminechari was based on a partial jaw bone and four sharp teeth discovered in a phosphate mine in Morocco’s Khouribga province. The unique characteristics of the teeth led to claims about the species’ distinctiveness within the order of mosasaurs and among tetrapods.
Contradictions in Mosasaur Biology
Further analysis by Sharpe and his colleagues revealed troubling contradictions in mosasaur biology, raising concerns about the fossil’s authenticity. The abnormal arrangement of teeth, with two of them sharing a single socket, conflicts with the known dental patterns of mosasaurs. Additionally, the presence of medial overlap on two teeth indicates a potential forgery.
Challenges in Verification
Despite efforts to CT scan the fossil for confirmation, difficulties arose in communication with the original study’s lead author, Nick Longrich. Sharpe and his team faced obstacles in obtaining access to the specimen for further examination, highlighting the importance of transparency and collaboration in scientific research.
In conclusion, the discovery of Xenodens calminechari serves as a cautionary tale in the field of paleontology, emphasizing the need for rigorous verification and ethical practices to preserve the integrity of scientific findings. As the debate continues, researchers and experts are urged to prioritize the authenticity of fossils to advance our understanding of prehistoric creatures.
