Confocal and micro-CT data of Varcalium lawrencei, holotype, NIGP177336

This dataset contains the raw confocal laser scanning microscopy (CLSM) slices and X-ray microtomography (micro-CT) slices for the holotype of Varcalium lawrencei (NIGP177336) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "A new marsh beetle from mid-Cretaceous amber of northern Myanmar (Coleoptera: Scirtidae)" (DOI:10.1038/s41598-022-16822-y).

Confocal images were obtained with a Zeiss LSM710 confocal laser scanning microscope, using the 488 nm (Argon) laser excitation line. The original CZI files are provided, which could be opened by the ZEISS ZEN software.

Micro-CT data were obtained with a Zeiss Xradia 520 Versa 3D X-ray microscope. Scanning parameters were as follows: isotropic voxel size, 16.916 μm; power, 4 W; acceleration voltage, 50 kV; exposure time, 2 s; projections, 2001. The TIFF stack is provided.
