Confocal and micro-CT data of Yassibum yoshitomii, holotype, NIGP200730

This dataset contains the raw confocal laser scanning microscopy (CLSM) slices and X-ray microtomography (micro-CT) slices for the holotype of Yassibum yoshitomii (NIGP200730) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "An unusual Cretaceous beetle with affinity to Anamorphidae (Coleoptera: Coccinelloidea)" (DOI: 10.7717/peerj.18008).

Confocal images were obtained with a Zeiss LSM710 confocal laser scanning microscope, using the 561 nm (DPSS 561-10) 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, 1.6339 μm; power, 3 W; acceleration voltage, 40 kV; exposure time, 4 s; projections, 3001. The TIFF stack is provided.
