Washington: Researchers used a computed tomography (CT)scans and 3-
A printer that makes accurate copies of bone fossils.
Fossils are usually stored in plaster models or jackets to protect them from damage.
Obtaining information about fossils often requires the removal of gypsum and all deposits around it, which may result in loss of material and even destruction of the fossil itself.
German researchers studied the use of CT and 3-
The D printer undamaged the fossil bone from its surrounding sediment matrix and produced 3-
The seal of the fossil bone itself.
\"The most important benefit of this method is that it is not
The risk of damage to fossils is small, \"said study author Berlin Sema Issever, who is from the radiology department at Mitte, Charite Campus, Berlin.
\"And it\'s not time --
Prepare for consumption as a tradition, \"said Issever.
Issever and his colleagues applied this method to an unidentified fossil at the fur Naturkunde Museum, the main natural history museum in Berlin.
Fossils and other similar fossils were buried under the rubble in the basement of the museum after World War II bombing.
Since then, it has been difficult for museum staff to classify and identify some plaster jackets.
Study of CT examination on unknown fossil zone 320slice multi-Detector system
Compared with the surrounding matrix, through the different attenuation or absorption of radiation of the bone, the rigid spine can be clearly described.
After studying the CT scan and comparing it with the old excavation drawings, the researchers were able to trace the origin of the fossil back to the excavation of Halberstadt, from 1910 to 1927, a major excavation was carried out in a clay pit in southern Halberstadt, Germany.
In addition, CT studies provide valuable information on fossil status and integrity, showing multiple fractures and destruction of the anterior edge of the spine.
In addition, the CT data set helps researchers to establish accurate reconstruction of fossils through selective laser sintering, which is a use of high
Combine the materials together to make 3-D object.
Issever points out that these findings are 3-in technological advances and cheaper-
D printers are becoming more and more common as a research tool.

\"Printing can be easily shared, so valuable information on rare fossils can be obtained by other research facilities, otherwise these fossils will be restricted,\" Issever said . \".
The study was published in the journal Radiology.
