A new study published in Radiocarbon reveals that micro-computerized tomography (micro-CT), a widely used technique believed to be non-destructive, may actually impact the preservation of fossils. While micro-CT allows detailed, high-resolution 3D imaging of fossils without physical cutting, researchers warn that the X-ray exposure could potentially alter fossil material and erase critical internal information. This finding raises concerns about balancing fossil examination with preservation for future study.
