Fossil wood samples dated by the CIRAM laboratory
The CIRAM has dated two fossil woods whose exceptional preservation is explained in particular by their burial in a humid, oxygen-poor environment.

Since 2005, CIRAM has been revolutionizing science for the benefit of art, industry, and archaeology, by offering high-precision analyses.
Contact our teamsCreated in 2005 by Richard Chéret and Olivier Bobin, CIRAM was founded with a strong ambition: to make analytical sciences accessible to players in the art market, archaeologists, and industrialists. At a time when few laboratories offered a multidisciplinary approach, CIRAM stood out for its ability to combine scientific expertise with a keen understanding of business challenges.
The company rapidly expanded internationally, with the creation of CIRAM Corp in New York in 2011, followed by a strategic partnership in Hong Kong in 2012.
In 2014, the construction of the headquarters in Martillac, in the Bordeaux region, marked a new stage, equipping the laboratory with cutting-edge technical resources to meet ever more ambitious projects.
As of 2017, CIRAM doubled the capacity of its materials analysis laboratory and inaugurated a state-of-the-art carbon-14 dating laboratory. To meet the constant increase in demand, we also doubled our radiocarbon production capacity in 2022, and then tripled it in 2024.
The year 2025 marks the launch of our laboratory's expansion with the creation of an additional 500 m². The work, as well as the complete renovation of our premises, will be completed in September 2026.
In 2026, CIRAM is also strengthening its technical platform with the integration of the AMS LEA from Ionplus (Zurich, Switzerland), an accelerator mass spectrometer entirely dedicated to radiocarbon analysis. The laboratory thus becomes the only private European player to have this technology.
