Confocal and micro-CT data of Crassiungula lawrencei, holotype, NIGP206002

This dataset contains the raw confocal laser scanning microscopy (CLSM) slices and X-ray microtomography (micro-CT) slices for the holotype of Crassiungula lawrencei (NIGP206002) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "Crassiungula gen. nov., an enigmatic genus of scarabaeoids from mid-Cretaceous Kachin amber (Coleoptera: Scarabaeoidea)" (DOI:10.3161/00034541ANZ2025.75.1.004). 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, 4.8649 μm; power, 3 W; acceleration voltage, 40 kV; exposure time, 4 s; projections, 2501. The TIFF stack is provided.
