A cretaceous fly trap? Remarkable abdominal modification in a fossil wasp

The dataset contains all original .TIF format photos of the CT scanning data about Cretaceous Sirenobethylid wasp, No. CNU-HYM-MA2015119. Number of the TIFF images is 1718. Volume rendering and 3D reconstruction were performed using the open-source software Drishti 2.4 [1], made by the Australian National University. The specimen was collected from Noije Bum hill, about 18 km southwest of Tanai Village in the Hukawng Valley, northern Myanmar (26° 21' 33.41" N, 96° 43' 11.88" E) [2, 3]. All amber specimens are stored in the Key Lab of Insect Evolution and Environmental Changes, College of Life Sciences, Capital Normal University (CNUB; Dong Ren, Curator), Beijing, China [4, 5].

Methods
The amber No. CNU-HYM-MA2015119 was scanned at the micro-CT laboratory of YKLP (Yunnan Key Laboratory for Paleobiology) with an X-ray microscope (3D-XRM), Zeiss Xradia 520 versa. Scanning parameters are as follows: beam strength: 60 kV/5w, filter: no, resolution: 1.94 μm, exposure time: 5 s, number of TIFF images: 1718.
