Scientific Correction: Oldest Known Lepidosaur Discovery Updated with Complete Data

In a recent development in paleontological research, Nature has published an author correction for a significant study on the oldest known lepidosaur and the origins of lepidosaur feeding adaptations. This correction, published on November 10, 2025, addresses important data accessibility issues from the original September 2025 publication, ensuring that the scientific community has complete access to all supporting materials for this groundbreaking research.

Understanding the Correction

The author correction specifically addresses an incomplete Data Availability section in the original publication. According to the Nature correction notice, the initial version failed to include comprehensive information about additional data resources available to researchers. The updated publication now properly references the complete phylogenetic data sets, detailed analyses, and 3D segmented models derived from CT scans, all available through the Dryad digital repository at https://doi.org/10.5061/dryad.cvdncjth4.

Research Significance

This study represents a major advancement in our understanding of early reptile evolution. Lepidosaurs include modern lizards, snakes, and tuataras, and understanding their earliest representatives provides crucial insights into the evolutionary pathways that shaped modern reptile diversity. The research focuses particularly on feeding adaptations, offering new perspectives on how these creatures developed specialized mechanisms for capturing and processing prey.

International Collaboration

The research represents a collaborative effort across multiple prestigious institutions. Led by Daniel Marke and Michael J. Benton from the University of Bristol's School of Earth Sciences, the team includes researchers from the University of Edinburgh, University College London, The Natural History Museum in London, the European Synchrotron Radiation Facility in Grenoble, Diamond Light Source in Didcot, and Queen Mary University of London. This international collaboration highlights the global nature of cutting-edge paleontological research and the importance of data sharing across institutions.

Data Accessibility in Modern Science

The correction underscores the critical importance of complete data transparency in contemporary scientific publishing. By ensuring that all supplementary materials—including complex phylogenetic data and detailed 3D models—are properly documented and accessible, the research team reinforces the principles of reproducible science. This approach allows other researchers to verify findings, build upon the work, and conduct their own analyses using the same foundational data.

Implications for Future Research

The availability of comprehensive data sets, particularly the 3D segmented models from CT scans, opens new possibilities for digital paleontology. Researchers worldwide can now access detailed virtual representations of these ancient specimens, enabling studies that might not be possible through physical examination alone. This digital accessibility represents a significant step forward in how paleontological research is conducted and shared within the global scientific community.

The correction process itself demonstrates the robustness of modern scientific publishing, where errors or omissions can be promptly addressed to maintain the integrity of the scientific record. This ensures that valuable research contributions remain reliable resources for future investigations into reptile evolution and paleobiology.
